Question 73: "Hey Joe, All of the warbirds I have were all ARF's(2). What do you
think would be the best warbird kit for me to try. I don't think I will
have a problem with it as I am a full size aircraft mech. but all of that
shaping of wood has got me a little spooked.
Thanks, Joe"
Joe: "Hi
Joe Depends on what type of warbirds you want to do. There are several
types of warbirds as well as several designers making various sets of
plans. Most you don't have to shape any wood more than a wingtip or fin
tip and those are pretty easy to do. For a first bird I would suggest
a Nick Ziroli Design http://www.ziroliplans.com/welcome.html or a Roy Vaillencourt Design http://vaillyaviation.com/ they both are very scale and loaded with instructions. There are others
like Brian Taylor who is very scale outlines but I personally don't care
for his box construction methods and there is a lot of carving on some
plans like his 109 which the fin is carved and complicated to carve I
know I tried and gave up frustrated as I can carve but not that good.
So stick with Nick or Roy for your first bird to get used to it and because
they are so easy to build and there are so many construction sites out
there like mine where you can just follow along. Joe "

Question 74: "Hey Joe, keep up the good work; I am following your Hurri with great
interest! I too would like to build something a little bit bigger for
once, I only did sports scale up to now. But I have one problem; I sit
in a wheelchair. That makes it a little bit more difficult to move big
parts around, especially in the workshop. If I build from a plan, can
I divide the fuselage in two parts, without putting in too much weight,
and having the risque that my plane falls out of the air? I would put
rudder and fin servo's in the back. Thank you very much, Hans"
Joe: "Hi Hans Yes I have seen fuses that break in the middle for easy
transport. I have never done it but it shouldn't be too hard it would
be more like a wing. What I would do is figure out where you want it to
break and make sure your fuse formers aren't full of too much lightening
like most are. I would then get 2 sets of wingtubes from somewhere like
Gator RC http://www.gatorrc.com and mount one on each side of the fuse either on the sides or one on top
and one on bottom (my choice). That wont add too much weight and then
just figure out a way to fasten it all together it shouldn't add more
than a half lb of added weight maybe a lb so it shouldn't affect flying
characteristics and shouldn't cause you to add a ton of weight to balance
since most of the joint would probably be close to the CG. Joe"

Question 75: "Hi. I am building a Top Flite P47 Thunderbolt .60 size. The kit
recommends using monocoat but I would like to try something else. I was
thinking of glassing it but am very concerned about it's weight. Is it
at all common to simply use epoxy resin to "glass" the plane
without using any fiberglass? Basically just brushing the epoxy on, then
sanding and recoating several times. To me, it seems that the epoxy coating
would be fine for this aircraft since it only requires monocoat. Any advice
here would be great. Thanks.
Steve St.Clair "
Joe: "Hi Steve I cover Glassing on my Help Page at http://home.mchsi.com/~jahuntley/help.html. I use polyurethane rather
than epoxy resin as it is lighter. as for the monocoat weight difference
you will find if you use the technique I show with the poly U and .5 oz
glass you wont even see more than a couple Oz's difference in weight and
give you a much better finish. You can use the Poly U without the glass
but you lose strength. Ever crash a plane with monocoat? the monocoat
helps to lessen the damage by providing a tough skin to your balsa also
keeps you from accidentally punching a hole in the sheeting. Thus if you
glass you want to create that same protection thus it is not good to leave
the glass out of the process. I would suggest reading my article on how
to glass with poly U in there I cover all the different types of resins
used for model glassing and the pro's and cons on each. Joe "

Question 78: "Hi Joe I am finishing up my zirolli corsair and have been looking
at color schemes and I kind of like some of the early f4u-1 birdcage canopy
corsairs . Is this canopy available or is there a way to convert the zirolli
canopy to the birdcage type? I will probably run a inquiry on RC UNIVERSE
TOO but I thought you might have some info on it . Thanks Tom "
Joe: "Sorry Tom I don't know of any but here's an easy way to make your
own. Use the inside of your current canopy as a mold. Use some plaster
of paris and pour into the inside of the canopy and let harden. When it
is cured pop it out and let it dry for a day or so. Then put a few coats
of poly urethane, varnish, shellac anything like that onto the plaster
and when dry wetsand smooth then using some rubbing compound buff it up.
Put several coats of Mold release on and then glass over it with 2 or
3 layers of glass. When its all cured draw on the glass the frame structure
you want, trim it up and you have your frame. You can then use the old
canopy for the glass for your frame. Joe"

Question 79: "Dear
Joe: How many fiberglass components are allowed

fiberglass was or is used? I am very new to this hobby and need all of
the help I can get. Where can I get a sliding canopy for the Ziroli Corsair
93" wingspan? Thanks Lou"
Joe: "Hi
Lou there are no points deducted for glass parts. The only problem you
would get into that with is if you were in designer class and did not
make your own molds. In designer class the contestant must design from
scratch, create his own molds and parts if glass is used, and fly the
plane. Expert or sportsman class you have to build it and fly it but can
use either a kit or scratch build it the thing is if I remember correctly
you must disclose any parts you did not make where they are from but I'm
sketchy on that. Go to http://modelaircraft.org/templates/ama/PDF-files/Rulebook/scale.pdf it will open up a pdf file of the current scale rules. Save that file
and print it out it will have all the current info in it. As for a sliding
canopy you will have to make your own I don't know of any kits but it
isn't hard to do goto http://www.rcuniverse.com/showthread.php?s=&threadid=107994&forumid=34&highlight=sliding+canopy rcuniverse thread there Branded did a nice article on doing a sliding

Question 81: "Hi Joe, As you already know I am doing a Don Smith B-17. I was wondering
just to attach all the glass parts to the airframe on such a plane so
they look scale. I really don't want to put a bunch of off scale size
screws in it and ruin an otherwise good looking plane. It looks like the
side windows would be easy enough, but what gets me is the nose glass
and turrets. Thanks, Hans"
Joe: "Hi
Hans, well by glass I am assuming you are talking about all the canopy
stuff so here's how I did it on the one I built and do it on all my others.
Just get some 200 mile an hour tape and tape it to the plane then ya don't
get those ugly screws :0) Seriously, what I do for all canopies and bubbles
is to take the acetate parts and hold them in place and trace around them.
On the nose and tail you wont be able to but you already know where the
outline is. I then take my xacto and cut a groove on the bubbles and make
a recess for the nose and tail. I can then recess the bubbles into this
slot which I put some canopy glue in and then fare around the outside
of it this gives me a nice flush fit bubble/turret that is solidly glued
in place. I should point out that if the part allows I cut it long so
I can do this. For the nose pieces I recess the wood slightly glue the
piece in place and fare over it. Now when I am worried about it coming
loose before I fare the outside in I cut the tips off some pins and put
them in through the plastic and into the balsa inside. I use small headed
sewing pins so the head holds them in place and can be fared over. If
worse comes to worse I get those micro screws like use for eyeglasses
but with long shanks so they bite into the wood and screw the glass pieces
like the nose and tail to the fuse (after gluing it in place) I then fill
the screw driver slots in them and convert them to rivets. If you look
at most aircraft you will see that the canopy/greenhouse frames have rivets
along them thus the screws hold the glass and turn into scale rivets.
This works the same for fiberglass parts as it does for acetate parts.
If I have you confused by now then I did my job so just email me with
any other questions you need explained better. Joe"

suggest finding a good set of 3 views and then goto the top flight page
and download their construction manual if you don't already have the kit
and compare the differences. The manual has small versions of the plans
in them and you can use them to check your outlines. Everything else is
cosmetic the only thing a person needs to look for when wanting to do
a scale model is the outline as cowl, scoops, all that other is cosmetic
and can always be custom made the way you want. Joe "

Question 88: "Hi Joe, I am a 14 year old and I have been flying for a little over

I can fly solo on my Hobbico Superstar Select 40 now am looking into purchasing
another plane. Since I am planning to eventually get into warbirds, I
was wondering what I should get for a second plane. I only have so much
money that I can spend due to my age, but I hope on getting a summer job
at a local airport which will help with my money problems. What do you
think would be an ideal plane for my second one? Should I get a warbird
right away, or get something else? Also, what type should it be (a kit,
an ARF, etc)? And lastly where would you recommend that I purchase this
second plane? Thanks,"
Joe: "Hi
Aaron welcome to the hobby. There are so many planes out there it is mind
boggling. I wouldn't suggest an ARF because you will end up disappointed.
Not that some ARF's aren't nice but some aren't built the greatest and
limited offerings for warbirds and the warbirds just don't look good covered
in monicoat and decals. They are ok for someone like you just getting
going but they don't teach you anything. I suggest you get a kit and build
your own. You will learn more about the building process which you will
ant to know later as I am sure you will sooner or later want to do a really
nice scale plane. Also you get the feeling of accomplishment when you
are all done of having built it yourself. I would suggest for a first
timer go with a Top Flight Kit http://www.bestrc.com/topflite/ as for the plane Might I suggest the P-39 Airacobra. The reason I suggest
this plane is that it will get you the best of both worlds. First it has
a tricycle landing gear which will make ground handling and take off's
a lot easier, and second it is a gentle flying plane which would make
a good second step from high wing trainer to a low wing trainer type plane.
You can also download the instruction manual in PDF format from their
site at http://www.bestrc.com/topflite/manuals/index.html then print it out
and read it over to see if you can understand it to be able to build it.
I have built one and they aren't too hard to build. This is nice because
you can study the instructions until you are comfortable that you or you
and your dad or a friend can build it. Then when you can afford to get
the kit it will be no problem for you. That's my suggestion for a next
step. Joe "

Question 89: "Joe, I am curious how you deal with seams with fiberglass? How wide

us in relation to working with seams in fiberglass. Thanks,"
Joe: "Hi
Jon I don't worry about them too much. I overlap maybe 1/4" to 1/2"
depending on my mood. Once you fill in the weave and give it a wetsand
any seam line will disappear. I use .5 oz glass and poly urethane and
you can almost not see a seamline. Remember most glass is very thin so
wont leave a noticeable line and once you are done glassing and wetsand
it in prep for painting all seams will disappear. I try to put all my
seams on leading edges if on the wing and on the underneath on the fuse
just in case but usually you never have to worry about them. Joe"

Question 90: "Mr. Joe, I wanting to tackle a "Ziroli" Hellcat as my
first build, I'll be getting the wood kit for it from Precision cut kits,
how hard are the Ziroli kits to assemble? I'll need alot of help....is
this a good idea? Tired of paying so called professional builders alot
of money and would like to build my "own" plane to fly.....but
have never done it....what do you think, thanks Donnie in Texas"
Joe: "Hi Donnie you couldn't have picked a better designer as he is very
easy to build. Now not to get you too relaxed, but there will be a couple
areas you will have to learn patience with. The first will be the sheeting/planking
of the fuse. Since the hellcat fuse shape is what I basically call a 55
gallon drum with wings it will be challenging for you. You might be able
to use sheets to sheet it as it looks to be a nice fat round shape so
that balsa will bend around it easily. But since I haven't built one I
cannot say that for sure and you may have to plank it. Either way it isn't
hard just time consuming and tedious so when you get to that stage TAKE
YOUR TIME. One suggestion I will give you that works very well for me
and is a lot cheaper than redoing a section of the plane due to a screwup
is to buy yourself several sheets of posterboard and use that to make
sheeting templates. I will be illustrating this shortly on my 3 FW 190
projects I am working on.. Basically you just tape it over the fuse and
with a good sharp xacto cut it to the shapes you need for your balsa sheets
leaving a little extra so you can place it easier. The other place you
need patience is when setting your tailfeathers and wing. You need a good
incidence meter to make sure you have the incidences correct and also
get a second set of hands with you i.e. wife, one of your kids, next door
neighbor, parents, whoever you have available to help you at that stage.
You will need to measure from a center point on the fuse to each tip of
the wing and same with the stab to make sure it is straight. It is hard
to do alone at your stage in the game later when you get a few planes
under your belt you will come up with inventive ways to get around this.
Now that I got you quivering and saying what the heck did you get into
now the good things. With Nicks plans the fuse is simple can be built
even by a newbie in 4 or 5 hrs. He has a top view on his fuse plans there
will be thick dark lines you build a crutch over top the plans on top
of them dark lines it is 1/4 x 1/2 in balsa for the mains and crossmembers
and 1/8 x 1/2 for the diagonals/ every where a crossmember is is where
your fuse formers go. After you build the crutch and glue the wing saddles
in place you just flip the crutch over and jack it up about 6 inches See: http://home.mchsi.com/~jahuntley/hurricane/hur4.html my hurricane
fuse page. Remember my hurri fuse was built upside down as it is 1/3.5
scale and the bottom too tall. But you will follow the pics and his plans
you will have no trouble. The wing and tail is very basic lay down bottom
spars add ribs add glue and they done. If you need any help feel free
to email me or catch me on Yahoo Messenger under the nick ProfLooney.
