Question 145: "Hello, I am considering Hanger 9's 1.50
size p51. Does this plane because of its larger size have the same retract
problems as the 60 size? Or are the retracts beefier because the plane
is bigger? Also would a zdz 40 engine work on this plane? I know its
alot of power. (in my opinion you can't have to much!!) You can always
back off the throttle. But its nice to have it in a pinch. Would the
airframe survive with the extra hp. Thanks in advance, Zaim"
Joe: "hello Ziam as far as the retracts I wouldn't know as I don't use
them (robarts) I would check with Darrell at sierra precision for his
retracts. He has a set that fits the top flight giant P-51 and I would
assume they would fit the hangar 9 but I am not sure. They are better
retracts in my opinion and would hold up a lot more abuse. I use nothing
but darrells gear as I would rather pay a little more than have the
headaches I have had with robarts. (Remember this is only my opinion
and not that of rc warbirds) as for the ZDZ 40 all I can say is if it
will fit go for it. I like to put the biggest engine I can afford in
as you said can always keep off the throttle but have the extra power
if you need it to get out of trouble. Joe"

Question 146: "Hey Joe, I am going to be starting on my
Ziroli Stuka soon and I was wanting to go with the Zenoah G-62 for power.
I was however concerned with concealing the exhaust under that narrow
cowling. I have seen many pictures of Stukas with a gaudy muffler hanging
out the side and I would like to make mine as clean as possible. Any
suggestions? "
Joe: "Ian, I don't think you should have a problem with it, however
I would suggest a pitts style muffler for it over a big canister one.
You might also check with century Jet as they make scale working exhaust
or custom exhaust reasonably maybe they can help you out by making you
an end that can bolt onto your 62 with a pipe running to the back of
your motor where you could mount a pitts style muffler. There are probably
stock fittings you can by that divert your exhaust around to the rear
where you can mount your
muffler. I would tell you to go with a ZDZ engine because they have
rear OR side exhaust but I just found out they aren't available any
more. Joe"

Question 147: "Hi Joe! After reading your article on your
website about glassing with Polyurethane I would like to have your opinion
about using 0.2 oz/sq.yd fiberglass tissue that I saw on the web at
www.cstsales.com/Fiberglass/fiberglass-tissue.htm instead of 0.5 oz/sq.yd.
Can I expect the same finishing results at a lighter final weight for
my TopFlite Cessna 182 Skylane. Many Thanks
Jean-Pierre "
Joe: "Hi
Jean-Pierre yes you should expect the same finish with it. The glass
cloth you use isn't the concern for the weight but the material you
use to glass with thus you would be using the same material i.e. the
poly U so it will have the same finish weight as if you used the .5.
While it wont weigh the same exactly I think you get my point. You will
be using a lighter glass and since it is a tissue wont need as much
to fill the weave so will give you a lot lighter finish. Joe"

Joe: "Chris What I would do is use balsa blocks or something like pine
and carve your canopy shapes. After you get it the way you like it use
something like clear polyurethane and give them several coats. Next
wetsand them smooth and take some kind of rubbing or buffing compound
and buff them up really good to get rid of any scratches. I would use
these to Pull your own canopys from clear styrene. Joe"

Question 150: "Hi Joe. I have a question about my TF P-39.

sides in one piece. Are you supposed to cut it in half and then attach
it? Basically saying, the slot where the middle of the joiner wire is
is inaccessible to me (the fin is glued on). Im sorry for the
vague and broad question; Im having trouble wording this. Any
suggestions will be greatly appreciated. --Aaron "
Joe: "Aaron the problem is your fin being glued on. you were supposed
to have it pinned in place or something just to check it and then remove
the fin to place your wire in the slot (see step 8 on page 17) I think
that might be where you are coming into problems. you may have to remove
the fin in order to get it to go together correctly Joe"

Question 154: "Joe, I agree with your recommendation for
the Elmers Polyurethane glue. It takes about 20 minutes till it hardens,
and about 4 hours till it fully cures. The one question I have is, can
the poly glue be used instead of the CA glues on the aircraft. Since
I do not have a time constraint, I can wait 2 hours between completing
the next steps in some cases, and in others, Ca offers a more viable
alternative. "
Joe: "Lewis
Poly Urethane glues are nice for planking. when I plank I run a bead
along the edge and then CA it to the formers to hold it in place and
so I can run several planks that way. CA I just use to tack things in
place. The glue I would recommend using for Building is Elmers Titebond
II. It is made for the furnature makers etc and is very strong. I add
food coloring to mine so that when it is cured I can easily see it.
The problem with Poly glues are that if you dont put them on propperly
they are weak. Also if theres too much it foams everywhere making a
big mess. My feelings are that Poly glues are great for laminating stuff,
sheeting foam cores, and planking but after that they arent very good
for building. Gorilla glue is good it is basically the same thing as
probond but with a different name. Joe"

Question 155: "I hear that .50 oz cloth is what i should
use on a TF .60 size P-47. I can't seem to find it any where. Also what
would you use on the Giant TF P-47? Thanks Chris"
Joe: "Hi Chris .5 oz is all I ever use. Normally you can get it through
your LHS without a problem. A lot of times I will goto walmart and go
through their fabric department and get me some really light weight
cotton fabric to glass with. Matter of fact I will probably use it with
my 1/4 scale spit project. At $1.00 to $1.50 a yard in the sale section
(yard of fabric is actually 36 x 60) it makes for a lot cheaper than
glass cloth and works the exact same. Usually it is only like 30% cotton
but is is also just about the same as using .5 oz glass. If ya really
want to use glass Contact Mike Chilson at http://www.rcscaleproducts.com/ he doesnt have it up on his site yet but they have some big rolls of
the stuff they can cut to order. if you really have to you can goto
.75 oz cloth. As for the 47 I use nothing but .5 oz cloth on all of
my planes for Normal glassing of wings and fuse unless I use the cotton
fabric. If I am making a cowl or something I will use larger sizes.

Question 156: "Joe, My first visit to the site. Like finding

Contact Century Jets they are doing custom exhausts and i have seen
some of their work and looks nice. Heres a tip I have used once before
to get the scale USED looking exhaust. Goto your local gunstore and
get some BROWNING not Blueing stuff. they use browning for the muzzleloader
guys. I wont tell the authentic way to brown hehehe. then ask the guy
what he would recommend to thin it down or just look at the label. if
you thin it way down you can do increasing levels of browning from very
faint to darker. to give it the brown streaks some exhausts have just
dry brush with a paint brush. Some Brownings require the metal to be
heated first so be sure which you are using before you start so you
know how to apply it properly. Joe"

Question 157: "Really enjoy the site. My question, what

a link to a web site the explanes in detail how to accomplish all the

I am embarking on my first foam core wing. Thanks, Ron Berg"
Joe: "Ron
its gonna be really hard to explain the foam core stuff as i dont work
with it as i had too many bad experiences foam hates me :0) I would
suggest asking Jack Devine abt that as he is very good with foam planes.
As for the sheeting I can help you there. what you need to do is to
apply the poly glue to the wood itself or the core itself. I think it
is easier to do the core. then use a credit card type squeegee and spread
it out but you need to spread it out paper thin. then ya put the sheeting
on top flip the core repeat and then set the core in the core saddles
the core comes in and weight it down and leave it there overnight then
ya come back the next day and trim it up. its basically pretty easy
and thats the one thing I can do with cores heheehe. But Jack Devine
would be a good source and you can check his website out for more tips http://www.jackdevinemodels.com/ Joe"

brother in law and I are putting our first big scale war bird. We was

Joe: "Hi
Eric. well the thing I usually do is to set the spinner on top of the
prop and draw a rough outline of where I am going to cut and the shape.
I always make it smaller than it needs to be. Then I start cutting.
If it is a plastic spinner an xacto works good if it is Aluminim a set
of good sharp tin snips will work. After it is precut I then set it
on again and mark a little more. at this pint with a aluminum spinner
I will usually slow way down and file it the rest of the way to get
a nice smooth edge and so it wont start denting the sopinner. if it
is plastic I slice still with an exacto. I repeat this process until
I am done. Joe"

Question 162: "Hey Joe, just a quick question. Do many
modelers take on multiple building projects at the same time? Im
thinking of tackling a single engine Ziroli plane and multi-engine bomber
at the same time. Is this common or is it wise to stick with one at
a time? Thanks, Patrick"
Joe: "Hi Pat the basic answer is yes there are a lot of modellers with
multiple projects. I myself currently have 4 on the table I have had
as many as 7 when I was building for people. If you have the room to
separate the two projects so the kits dont get mixed up go for it. I
think for most modellers 2 projects at once would be easy to do. Remember
there are a lot of times where your project may be stopped. In my case
I have a couple on the side waiting on retracts and other things. Thus
you will always have to stop building for a week or so while waiting
on parts or have to stop while waiting on glue to dry when sheeting
or stop while waiting for glass to dry lots of things cause you to stop.
Whit I like to do is work 1 week on one project and the next on the
second. By the end of the week I am usually at a point where I need
to wait on something to dry or to make a run to the hobby store etc.
It also breaks up the monotony of working on the same plane day after
day.
Now there are those people that aren't into building and for them they
need to see the light at the end of the tunnel so if they get started
on 2 projects at once chances are neither will get finished as they
will get tired of building. You need to find out what kind of a builder
you are. A hurry up and get this silly thing built or someone who has
a lot of patience and when its done its done. Joe"

Question 164: "Joe, I didn't notice anywhere in the FAQ's
about building from plans. I want to build my first plane from plans,
and what is the best way to cut and make templates? What material should
I used for the templates? When cutting templates, do you cut outside
or inside the black line? Should I cut 2 kits at one time? Any information
would be greatly appreciated! Thank you, Richard"
Joe: "Hi Richard thats a good question I dont think I have touched on
before. first the best way to make and cut templates. there are 3 ways
of doing this the first being is to chop up your plans. this is fine
but what happens if you ever need to repair or want to build another
plane at a later date. I do not reccommend this way. the second would
be to goto a print shop and have a copy of your plans or partsheet made.
This is the best idea especially of the entire plans. depending where
you live most of the time you can get your entire plans copied for 15
to 20 bucks. some people on the east or west coast it seems though cost
them 75 cents a sq ft so its just as cheap to buy a new set of plans
later. Me its usually around 28 cents a square ft . You can also find
places that have wide format scanners and can scan your plans in for
you and burn to cd for between 5 and 12 dollars a sheet. this is the
best method as over time your plans wil shrink and contract with weather
so if say a year from now you want to build another plane you can print
from your scans and they will not be skewed due to tiff files dont expand
and contract.
first use either a sharp pair of scisors or an xacto and cut out your
part leaving the the touside lines showing. If you want to cut several
kits out you can get some think sheetmetal or aluminum and use that
for cutting out templates on and after you are all done with one plane
store them for later use. the most common method is to take some 3M
spray glue and spray the back of the paper that the part is drawn on
and then stick it to your wood. always spray the paper not the wood
as the glue will stay on the paper. if you spray7 the wood it wont hurt
then lay down all your templates onto it but when you are done your
wood will be a little tacky for a day or so.
when i used to cut out my own kits til i found out laser cutting is
just a little more expensive and a lot more accurate I would spray 3
m glue on the back of my wood and stack several layers enough to cut
2 or 3 planes at once. the advantage is if you ever need repairs you
have the pieces already cut. also it will take you the same time to
build 2 planes at once as it does 1 and you can then sell the second
plane to get back the money you spent on wood etc and help buy the expensive
stuff like servos or engine.
as for the lines it really doesnt matter which you do. most people cut
way outside the lines and sand to the lines and others cut on the lines
and sand til the lines are gone. either way the key is to be consistant.
if you sand to the lines on 1 sand to the lines on all you parts same
with sanding the line off. Joe"

question, since lacquer based Poly U melts the last coat a little to
chemically bond to itself, could i apply one layer of the .7 cloth,
then when it has dried apply a second layer of glass in the same fashion
for additional strength. Then finish with the aditional coats of Poly
U as you have specified? Thanks for your help. Ron"
Joe: "Hi Ron yes that will work it is basically the same as you do when
you overlap the glass say on the tailfeathers on the plane. you should
have no problem doing that. Just remember if you have foam cores make
sure they are sheeted well as the laquer based will attack the foam
directly. i havent heard of any problems with foam cores as most people
use the sanding sealer first. If you are concerned the water base will
work too just takes forever to cure. Joe"

best way too do (I mean what is the best plane too fly and best scale)
building is not the problem. The wood from the Smit plans can I use
for the Ziroli I think, I don't have any hardware yet. In Holland is
an seeing "It is better too turn half way than lost totally".
Thanks a lot. Dick"
Joe: "Hi Dick I am not a P-51 nut so I cant really tell you much on
the scale outlines of the two designers. I will tell you thiws and that
are both designers do their research for their designs and either can
be a contest winner. The Ziroli is 1/5th scale and the Smith is 1/4
scale, if you go by the old rule of thumb bigger is better. It really
depends on you and what you can haul and store. the ziroli plane is
smaller and easier to transport and store and the smith is a lot bigger
making storage and transport something to consider. My final verdict
is you cant go wrong with either oif them for scaleness and flyability
just have to pic which size you want. Joe "
