Question 169: "Twin man, My name is Chris, I am from Louisville K. Y. I am finishing up a Joltin Josie, I am using the RCV 91 CD engines running 12*6 three blades. Installing a intelligent glow driver from Nelson Hobby.On the radio gear I am using Hitec HS-475 on all surfaces except the elevator a mighty mini 225MG 6V battery.sing an electrodynamics EDR 111 optic isolator and a 4.8V for the receiver.My question after that long intro: should I install a rudder Gyro?I have some twin time. I built and fly a great planes P-38. I really respect your experience and writings.I see that you have one of the earlier KMP P-38's.How does it fly? What kind of flap settings do you use? I am using a Eclipse 7 radio. If you have video of your plane I would love to see it if possible. Thanks for any help.The closer I get to the maiden the tighter my rear seems to get.Ha HA Christopher "

Twinman: "Hi Chris, No, I do not own the KMP. The KMP used in the comparison was a friends. I own the VQ version, which is more scale like...in my opinion. As for the rudder gyro. YES, YOU BET...Absolutely...get the idea? The P-38 from KMP or VQ IS NOT like the profile. It WILL not fly well on an engine out. Wing loading is much higher, as is the speed. The engine spacing on the KMP is much wider than scale and do reduces the ability to fly on a single engine due to differential thrust. No, I am not complaining about KMP, but this is true on any P-38. The rudder gyro is good insurance, but....you knew there would be a BUT....the rudders on the P-38 are too small for effective control. Personally I use one gyro on the rudder and another on the ailerons. This dampens the yaw and subsequent spin,of engine out, to a rate that you can react. Be sure you can ALWAYS fly coordinated aileron and rudder control to again prepare for the worst..that I pray never happens to you! As for the flap setting, the VQ uses a sophisticated fowler system, verses a fold down flap on the KMP. Follow the recommendations of the manufacturer..but personally go to the high side, as landing a P-38 by any manufacturer is faster than you may be used to and the flaps do help. One more recommendation.. Set the rudder throws as high as you can to aid their effectiveness.
Good luck and send pictures.

Question 170: "Twinman, I enjoy reading your advice and thought you might enjoy hearing about my Twinstar. The Twinstar is my first flying twin. I'm building a VQ A-26 buy wanted to get twin experience with the Twinstar. I live and fly at 5000 feet so two Saito .56s power my Twinstar. I doubled and split the strip ailerons, to have flaps. I also doubled the elevator and tripled the rudder. Also I built retracts with trailing link suspension. One and one quarter inches were added to the center of the wing so I can use 11 inch propellers. I also installed two 4 ounce feeder tanks in the fuselage to have 8 ounces per engine. At 8 pounds it has a heavy wing loading but flies very well. It likes to fly fast and I use crow to slow it down and land. During the early flights it was disappointing how ineffective the rudder was; all it would do is make the plane crab. I removed all the out and down thrust from both engines and mixed throttle to rudder. It now flies like a real airplane. I'm trying to learn to use rudder but not so good yet. So far I have not lost an engine. Ray "

Twinman: "Hi Ray, Sounds like you are really having fun and I like the modifications. Two Saito 56's on a twinstar? Wow. Save those for the VQ A-26..Shh...they just got in the K model with wing tanks on the newer model of the A-26. Have not seen complete, but should be good. Always do the vertical test and I hope and pray you do not need to experience single engine flight. Keep working on the rudder control as automatic..you REALLY do not want to learn with one engine very quiet. Send pic's of the A-26.
Good Luck, Twinman"

Question 171: " I have just purchased a VQ P 38 and would like to use the same retract and brake set up you have described in your review. I was wondering what were the specific retracts you used from thethe company you mentioned. Thank, Jason"

Twinman: "Hi Jason, The retracts are Spring Air and are available at some discount from VQ and in stock as well as the oleo struts. The brakes also came from Spring Air via an outside source, but I would suggest you contact them directly for the source.
Good Luck,
Twinman

Question 172: " Hi Paul, hi George, I am planning to build a Henschel 129 as a second twin, after a small electric Blenheim (see pictures).
This german aircraft should make a perfect model, with its large straight wing and box-like fuselage. Another nice feature of the Hs129 is that the engines rotate in opposite directions, which should take care of torque problems. However, on this aircraft the props seem to turn in the wrong direction. Seen from the front, the port Gnome & Rhône engine turns clockwise. Historical texts say the germans choose this solution to ease recovery when flying on one engine. I would think this makes the yaw even worse, adding adverse torque effects to offset pull?
I don't expect problems with the model as I will be using electric motors and my Blenheim flies straight with both props turning in the same direction. So I intend to make the Hs129 just like the real aircraft. However I find this confusing; maybe there is another benefit in having the engines turn this way?
thanks in advance,"

Twinman: "Hi Laurent, For the models the counter-rotating props are really not necessary in my opinion and I have flown both versions on the P-38 which is probably the most famous to have counter-rotating propellers.
To quote the various articles about the P-38.

"The XP-38 had been powered by two liquid cooled, Allison V-1710 engines turning 11 1/2 foot Curtis Electric, inward turning, counter-rotating propellers. With the YP-38s and all subsequent Lightings, the propellers rotated outward negating torque when both engines were operating (A batch ordered by Britain did not have counter-rotating propellers.) "

The idea was on such a small and high powered and high wing loaded plane, the counter-rotation would cancel the torque of the engines, making for a more stable flier and less problems when rapidly going to full power at low airspeed........WHICH YOU COULD NOT DO on conventional single engine fighters.
Sounds like a neat project. Please keep us posted.

Question 173: " George, I know Mookie1 tickled your interest when he converted the VQ P38 to electric. Well I'm going to give the NitroModels 90" version a whirl. And yes I've flown twins, have a 52" and smaller version P38. Some of us just don't learn. Anyhow, being that the electrics seem to be less prone to the "engine out, death spiral" would you still recommend going with gyros on this one? And if so, which ones would you look at using.
Thanks, Brad aka "Glacier Girl""

Twinman: "Hi Brad, No, I would not see the need..( Famous last words) for a gyro in an electric. They are great for a tail dragger or something like a P-38 that could go out of control on loss of an engine. In your case, that is VERY remote. Please consider to do a build story here in Rcwarbirds.com as more and more of us are taking a hard look at electrics. The Mookie! conversion shocked me, as it took off and flew like mine with two ST 90's.......Uh...can you put cards in the props for that propeller to engine sound? Tee Hee.

Question 174: "George, I was wondering if you have any experience or info with Hal Osborne's P82 Twin Mustang planset offered by Ken Kehlet? The accompanying build article that came with the plans (mine is the 101" enlarged copy) shows the model flying on a single engine thus suggest it is a docile flier. This is good since I thought it might make a good first twin to build and fly. Can you comment on its attention to scale line? From the plans it seems more standoff scale to me although photos of previous builds looks pretty convincing. Thanks in advance, Dave, Fresno, CA"

Twinman: "Hi Dave, I personally have not flown or seen that model, but I have done NUMEROUS similar conversions of standard planes into twin fuse twins. They are very stable with very good engine out characteristics. I usually do not recommend warbirds for first twins, and really still do not due to total investment, but IF you are headed that way..the twin fuse planes are very forgiving. DO learn to fly coordinated for the possible engine out. Good Luck and send pictures. Twinman.

Question 175: "Hello George, I one of those not following your optimum advice about "...not flying twins..." but we are air model enthusiastic and therefore.... I would like to buy the ARF C160 Transall (wing span 1800 mm) as my second twin model (first was...and still Is) the Hobbico Twinstar as you suggest. Do you have any experience with such model? Thank you for any suggestion or reccomendation. Stelvio"

Twinman: "Hi Stelvio, I personally have not flown or seen this model up close beyond the advertisements, but go to http://www.rcuniverse.com/forum/m_3949558/tm.htm at the associated site to Rcwarbirds and you will see a good set of posts on this model.

Question 176: "Twinman, Years ago I saw an article in Radio Control Modeler re: the Pica Duellist 2/40. I wanted to buy it but didn't. I now would like to find a kit and build it. Any ideas as to where I might find one? JoeJ"

Twinman: "Hi Joe, Unfortunatly the Pica dualist has been out of production for some time. Northeast aero has purchased the rights to that plane and is in the process of bringing it back out as an ARF. You can also look at the Pheonix from Cedar Hobbies, which is also similar.
You get brownie points for starting out with such planes, for experience, and not jumping into multi-engine Warbirds.
Good Luck, Twinman"

Question 177: "Twinman, I am planning to fly a VQ (89") P-61. I would like to run 2 1.20s, 4 cycles. Do you have:

1. recommendations for 1.20s, 4 cycles
2. I want to put on Pitts style mufflers, do you know which ones (vendors) will fit which 1.20s.?
3. Do you have a recommendation/know of the 'offset' for attaching 1.20s on this P-61.
4. I would like to run 4 bladed props...do you have a recommended vendor/distributor(where to contact/size/pitch to run.?
5. Advice or what to buy to run independent controls for the 2 throttle servos. As of now, I'm running a JR 631(6ch.) transmitter. How do I set-up independent throttle controls on the transmitter, i.e., using a 7 or 8 channel with 2 independent controls for the throttle..? Which set-ups do you know of that offer this feature....? Thank you,"

Twinman: "Hi Andre, The 120's would be a great power plant for this plane. As for mufflers, I would check with slim line, or Jtec
No offset is needed. Set straight on the firewall. The engine out is really good if need be. Learn to fly with the rudder just in case.
I would worry that you cannot get enough power with four blade props at anything approaching realistic sizes and still clear the nacelles with enough thrust. I know APC to name one does make such props, but I still would rather see you fly with a large diameter two blade..at least in the beginning. Always if possible run independent servos and IF possible on mixed together channels with individual control. Makes setting up MUCH easier, but is not absolutely necessary. If not mixed, then additional care for mechanical synchronizing must be done.
Good Luck,
Twinman"

Question 178: "TwinnMann, I need some advice on the VQ P-61, I am considering using 2 strokes, you mention in your review the proto used 90 Super Tigers, but had issues with inverted mounting, ( they would quit) Can the Super tigers be Mounted at a 90 (sideways) will they run better that way? Will the head stick out of the cowl? Or should I use OS Max 91’s, Will they run inverted?. Thankyou Jeff "

Twinman: "Hi Jeff, I tend to err on the safe side with advice. No, four to two stroke runs as reliabily inverted as sideways or up right due to fuel puddle at the glow plug. I have since flown this model numerous times with no problems. Advise would be to consider on board glow drivers for the plugs, just for that warm fuzzy feeling. Do I have glow drivers on mine, no, but I do have more single engine or engine out experience than I would care to comment on. Besides, the on board glow makes starting the engines safer and easier.
If you use two blade props, the 60 size engines will also work, but at the same size, why not go larger. It will fit basically inside the cowls.
Go for it and send pictures. Twinman"

Question 179: "George: I have just purchase this lovely bird……a real beauty with twin Satio 100’s with two three bladed props. One of the engines is modified by Satio to counter rotate. Also the exhaust systems have been modified, again by Satio, to exit out the back of the cowls, not the bottom or side. Very slick. My question is what scale is this? 1/5 or 1/6th? I can’t seem to find this information anywhere. This is my first twin and frankly I am quite sobered by the thought of flying her. Perhaps I should get a twin star or something cheap to fly first. Certainly I will practice on the simulator for some time prior to the first flight. I have also printed out your excellent flight report on the VQ P-38. I will study it carefully. Any other thoughts? Richard"

Twinman: "Hi Richard. Scale...well the original had a wingspan of 624 inches verses 84 on the Vq, so I would put this at just over 1/8 scale.
As to flying a P-38 as a first twin...PLEASE DO NOT DO THIS!!!, Lose an engine and YOU WILL CRASH!!
The P-38, to me is the coolest plane in the air, but has everything against it as a first twin. Have two now and owned five more. Very wide engine spacing, VERY heavy wing loading, and VERY SMALL rudders. All of which work very well.....as long as both engines are running. Lose an engine and you have an INSTANT snap roll.
Do you fly with coordinated rudder and aileron ALWAYS now?...No,,LEARN NOW!! Yes, proceed to next point....Consider Strongly to fly a cheap twin and LEARN single engine flight.
Consider Cedar Hobbies twinstick or their Phoenix as larger similar size planes. Reinforce the landing gear and learn engine out flying..then INCREASE the weight of the plane slowly to get used to landing and flying with heavy wing loading.
This is my two cents from having made almost all the mistakes you can make with twins,,,so I will now get off my soapbox.
Please send pictures of this engine installation, as it really sound good and GOOD Luck,
Twinman"

Question 180: "hi there i know this is nothing to do with warbirds but i have got a dual ace twin with twin la engines. I have seen many twins crash because i have seen a twin loose an engine is there any sugestions on flying or what to do in the event of an engine faliure steve"

Twinman: "Hi Steve,While I have not flown the Dual Ace, it is close enough to the Cedar Hobbies Pheonix that I think I can comment, not only on it, but ALL twins. Yes, they WILL fly on one engine, but to varying degrees. DO NOT TRY SINGLE ENGINE WITH A P-38!!
The biggest things are 1. Always use a helper with multi engines and hold the plane vertical before EVERY flight at full power. If an engine sags..even a little bit. DO NOT fly. Lose and engine on take off and it is VERY difficult to control and save. 2. Learn to fly with the rudder at ALL TIMES. You must use a lot of rudder control to handle an engine out and the amount changes as the air speed changes. If air speed it up, perhaps 25% rudder, depending upon wing loading, rudder size, and engine spacing will hold the plane in stable flight. Can you hold a plane in the air with one engine? Absolutely! But you cannot learn rudder control instantly and that is what it takes. I am not sure which LA engines you have, so further comments on aerobatics with one engine will go unanswered, and yes, you can roll and loop a plane with enough power on a single engine as well as take off, but rudder control is the key. The big thing is dependability so you do not have to practice this, but if you always fly with the rudder, there is a MUCH less chance of a Crash.
Good Luck,,,,,I will get off my soap box now. Ha Ha

Question 181: "Hello Twinmann, I am building a VQ P-61 , I am using O.S. Max 91FX two strokes, Is it possible to use the four bladed props on these?, (APC) I heard they were more efficient, Will they generate enough thrust? or do I need to stick with the 3 bladed, Also the kit I purchased has the SpringAir retract in it, I notice VQ is offering a different set of retracts from Shindau or something, were there problems with the Spring Air? Why the new retracts? Thanks Jeff"

Twinman: "Hi Jeff. I have tried the four blade props from APC on a ST 90. Was not happy with performance and load is VERY high. You cannot get scale look or diameter unless you go to a LOW pitch component system and the speed and cost would not be good. I am using the Master 13” three blades with ST 90’s and am happy. I know that VQ had a deal with Spring Air, but delivery is not good, so I can only guess they found another supplier. Good luck, Twinman"

Twinman: "Hi George Advice...Is this your first twin? ARG..Ok Do you ALWAYS fly coordinated with aileron and rudder for ALL turns? No, LEARN NOW!! Lose and engine and you are in real trouble. Yes, I know gas engines are more reliable than glow, ,True, but also Murphy's law follows us around. Us a helper and do the vertical full power test for around 10 seconds. If one engine changes, DO NOT FLY until they are reliable. They DO Quit and on take off, you are in real trouble. I personally have not flown this plane, but have seen it and looks like fun.

Question 185: "I'm building a KMP P38J...I saw on your web set that a lot of fliers have gyros in their lightning’s...This is the first WWII aircraft I've built...I am a WWI airplane builder and pilot...Any advice I could get would be appreciated...Thanks Tim"

Twinman: "Hi Tim, The gyros are to control or reduce to a manageable level,  what amounts to an almost instant snap roll of death on a P-38 in the event of an engine out. It is the most beautiful plane in the air, but VERY difficult to handle engine out. It DEFINATLY IS NOT A TRAINER!!  In general the P-38 is difficult due to wide engine spacing, VERY heavy wing loading, and VERY small rudders. The KMP is actually a little worse in that the engines are much wider than scale and the VQ.

Let me ask this question, have you flown twins before? If not, can I STRONGLY suggest that you find some easy to fly twin like the Cedar Hobbies Twin Stick and learn the characteristics of twins and SINGLE engine flight? Please believe me, I am not talking down to you or anyone else, but I have made most of the mistakes you can make on twins and I do not want others to make that many mistakes. Do you fly coordinated aileron and rudder control AT ALL TIMES!!?? If not, learn NOW and not with the P-38.

Today there is another product that will help control of engine out, that was not available with my first planes. It is called the Twinsync from Rcshowcase.com. Basically if you lose one engine, it reduces the remaining engine to idle automatically and then allows you to power back up. If you plane were mine, I would still do the gyros in either case. Good Luck, Twinman"

Question 186: "I am balancing a VQ P61, which I understand you have flown.  Gear up requires 3.5 oz more nose weight then gear down. Do you see any problem with this?  Tanks are empty.   Thanks for your time and advice.   Henry "

Twinman: "Hi Henry, Any plane must be balanced with the landing gear UP for stable flight. The nose gear and mains of the P-61, rotates back, and so the CQ moves back. You do not want a tail heavy warbird. The flaps will cause the nose to rise on landing and help support the extra weight. You will like the flaps, as it really slows down the plane. Now, MAKE SURE that all the flaps come down together and hold together. I have one that for some reason one of the flap sections was “Loose” in the down position. It looked OK, but under aero forces it would rise slightly. This causes the plane to turn with flaps..Not good. If you have a computer radio, you can program in 1/8”, NO MORE, down elevator, when the flaps come down. Good luck, and send pictures. Twinman"

Question 187: "Well I finally broke down and bought the Lightning from Tomas at VQ. Just like my 90" and smaller versions it will be electric. Just wanted to know if there were any bugaboos or tips to be aware of.  I did see your tool for popping the nasty bell crank connector on VQ's site, ingenious I must say….Brad

Twinman: "Hi Brad, I will be very interested to watch this come together. If you go to RCU
http://www.rcuniverse.com/forum/m_2120421/anchors_2165426/mpage_1/key_p%252D38/anchor/tm.htm#2165426
you will find an actual step by step build of the electric conversion. I saw the video that Mookie did and it took off from grass like mine does from Concrete. Real problems,,,you might check the adjustment of the fowler flaps. I have never had trouble with mine in dozens of flights, but I understand that some guys have. I have a Suburban and do not take the wings off.  It builds and with electric can be much more scale in appearance than the competitive ARF’s.  Send pictures!!! Good Luck,  Twinman"

Question 189: "I Planned to start to build some twins. I wanted to start with a ZP-38, but it apear to be the worst twin to start with... I could buy a 1/6 B-25 kit. Would it be better as a first twin ? What do you think of the twinsink system ?Best regards Gilles

Twinman:Hello Gilles. DO NOT do a P-38 for a first twin NEVER!! Even if the engines stay running, it MUST turn with coordinated aileron and rudder control at all times. It lands fast due to high wing loading. Consider some of the new arf's that are twins and have some fun..but..develop coordinated turns and LEARN TO FLY SINGLE ENGINE. Now, that sounds like a disaster in the making, but something like the Twin Stick or similar are fun to fly and give good CHEAP experience. It will take you MONTHS to build the Zeroli P-38. Use that time to gain experience and practice on twins. What do I think of the twin sync??? NEVER fly a P-38 without it!!! PERIOD!! Now, I still use two gyros on my P-38's to help control them...JUST in case. I feel that the P-38 is the greatest plane in the air, but it will bite you. Good Luck, Send Pictures. Twinman"

Question 190: "I’m about to order the new KMP Tiger Cat as my first twin. I read some forum about it and I’d like to use two Zenoah ZG20 in this bird. It must fit completely in the cowl and should be perfect. I must be at least number 1000 to ask you this, but I ‘m going to do so anyway: is the KMP Tiger Cat a good choice? I am an experienced pilot, but not with twins. Do you know the flight characteristics of the Tiger Cat (especially on one engine)? Fact is: it has a very large rudder, so I think it should be flyable on one engine, or am I mistaken?

Twinman: "Hi Marko, FYI, there is now another “ Cat” on the scene at Ceder Hobbies.
 http://www.cedarhobbies.net/index.php?id=product_desc&product=24

I will be doing a build on this model as we speak. Is around, with landing gear..around $300 USD less than the KMP, but have not actually compared the two side by side.Ok,,as to your question. Let me ask you this as I do all people who ask about a first twin. Do you ALWAYS use rudder and aileron coordinated in ALL TURNS AND AT ALL TIMES? If not, learn NOW!! My two cents is DO NOT fly twins if you do not feel comfortable to handle the rudder control automatically. Yes, you are going to use gas engines and they “Should be” more reliable, but they do fail and at that point is NOT a good time to learn to use the rudder. The only thing I usually suggest is to get a smaller less expensive model. Cedar twin stick for example and learn twin flight and engine out, without breaking the bank. No, I am not talking down to your skills, but do not want you to think twins and engine out are similar to single engines and make an expensive mistake. I have not flown this version of the tigre cat, but KMP or Cedar, should be the same for single engine. Just looking at it, yes, I would agree that the rudder is very large and a good distance from the engines, and so SHOULD help. The wings are very wide to lower the wing loading..good. Fuse is fairly tall to aid stability…good. The engines are widely spaced..not good, but the other three should help.The forums that you are looking at are at RCU in the twins forum. Keep looking for a separate build on the Cedar Version. Good Luck whatever you decide and send pictures to RCWARBIRDS Twinman"

Question 191: "I would like ask you about C-130 plane with four engines. How I must control these engines in my radio, all in one stick, by pairs; how?. A friend have one and we have that dude.Thank you for your time. Alejandro"

Twinman: "Ola Alejandro, Use four separate fuel tanks and four separate servos. Y harness all the servos together to one channel..Simple, but must make engine throttle response mechanically adjustable. Better radio- separate channels on the inner and outer engines-easier to tune and balance. BIG radio..separate channel for each engine and mix together. Very easy to balance and adjust..but NOT necessary. Consider the new Twin Sync Unit from Rc Showcase that can control all the engines and not only balance them at all times, but protect the plane in the event of one engine failure. Example..lose number 4 engine, number one will go to idle until you bring the stick to idle and come back up, same for inner engines. Good Luck..Remember..with helper (s). go to full power and hold the plane straight up..If one engine sags..fix it or do not fly. Send pictures. Twinman"

Question 192: "I am thinking of getting a he111 kit as a first twin its from Vanguard Vancouver its got an 89" wingspan. I was wondering if you had any experiance with this plane either the same company or other, any info on it will be usefull. Also will it be a good plane to start with?"

Twinman: "Hi Devin, No, I do not personally have experience with this plane, but looks neat. I DO NOT recommend any scale warbird NONE as a first twin. No, I honestly am NOT talking down to you or your skill level, but warbirds have heavy wing loading, small rudders, and wide engines. Not to mention expensive in time and money. Learn on a cheap twin..Cedar Hobbies Twin Stick for one to fly on a single engine well..and they are fun too. Fly that while you build your dream bird. Good Luck,,,and send pictures when you get through. Twinman"
