WOW, Your planes are looking great and guess what, you are
inspiring me to get some foam and build the "Old Fogey" from the
flite test website with the separate motor pod.
My problem here is that it is very hard to get that foam board +
eBay will only post A3 size which is not large enough. :'(

cant you use the paper covered foam board they use for signs and
display boards and just peel off the paper?

I have never seen that board. The sign boards they use here is
thin CORREX FLUTED PLASTIC similar to your blade material.

Most art supplies will carry 3/16" foam board. It is about $1-4
a sheet 20" x 30" Each of these planes takes 1 sheet and you
will have some leftover. Wing spans are 30-32" Overall length
is 20"
It isn't the most ideal material because it isn't the lightest
material for building. But it is cheap, strong and easy to work
with. It also takes a finish better than foam. EPP foam takes
paint well but is a pain to cut, sand and shape. EPS foam is
easy to work with but dents and cracks and is a pain to paint.
So, for the sacrifice in weight foam board is great. To deal
with the weight issue, the designs I have drawn have a lot of
wing area, and some tricks for keeping the tails light. All the
RC, motor, battery gear are up front to the balance point
correct.
Each of the Old Guy planes are about 8 oz all up with RC gear.
The high wing Yellow Plane is 8 oz and has 1 sqft of wing. The
WWI biplanes are about 9 oz but have more wing area. 1.3 sqft
for the Neiuport 17, and 1.6 sqft for the SE5A and Fokker DV11.
The Yellow plane tracks well and is faster. The Biplanes float
like kites.
Its been too windy to fly except for glide testing, but the
planes are ready for Maidens
With slow flyers it is critical to get the wing incidence
correct at 8 degrees, horiz stab 0 degrees, rudder square and
straight to centerline, motor 2 degrees downthrust and 2 degrees
right thrust to counter the torque.
The goal is to build a freeflight model that only takes a bit of
control to keep in an area. More throttle - more altitude, less
throttle - glide in for landing. The only way to crash is to
hold rudder hard over and spin in. If you let go, the plane
will fly itself. I use quick and light blips of rudder, and
generally keep my hands off the controls.

If you build me one that will be radio controlled and drop water
balloons--> I'll buy the beer.

I am working on the "Old Guy RC" website. A lot more to fill
in. Waiting for RC equipment in the mail, more photos, videos.
Test flights have been hindered by weather. A few takeoffs,
touch and goes, glide testing. So far so good. These planes
have a lot of torque on takeoff and need right rudder, just like
the real planes.
Check out the website and comment if you like. The plans are
free for download.

are those electric planes?
Where's my water balloons ?

Yes they are electric with Lipo battery. Run time is 10-20
minutes on a charge. Water balloons not included.

Well I finally got a few gifts in the post today:-
2 Lipo 900mah battery's, 2s.
1 Imax b6 charger.
Well I cannot believe how far these lipo`s have come in terms of
the power they can supply. I was still working in the Nimh age
!!!.
All I need to do is track down the foam board now and start
building.
I already have the brushless motor + esc + Dx4 Spektrum tx.
@lynx,
Have you fitted snow ski`s to those planes and flown them yet ?.
Happy flying with no balloons. ;D

Actually today I was able to fly the Tomboy.
The snow has melted enough to make the parking lot at our
warehouse dry. First I just let the tail lift off and take a
quick hop up and then down, taxied back and gave her a bit more
power. A little pull to the left from torque, some right rudder
and up. I chickened out and pulled back on the throttle and
landed in the snow because the wind was a bit much to be flying
near buildings and trees.
I walked to the car and thought, just some more hops. The
buildings sheltered the wind on the other side where I was
parked. Throttle up, a little right rudder and up she went
about 60 feet doing a nice right turn. I made a wrong turn,
corrected and brought her around into the wind, cut throttle and
landed.
The Tomboy is a sweet plane. Flies itself with trouble from me.
I hope you can find some foam board. Art supplies should have
it.
When the weather dries out a bit more I will take some video.
You may have noticed I have been refining the plans daily as I
test these models. Little adjustments to the downthrust and
right thrust built into the plans, adjustment of the CG. The
Tomboy needed a penny glued to the tail for balance it was that
close to being balanced off the board. It flies very nice with
the balance right at the bend in the airfoil.
