Further Description/Back Story

Hi, I’m Bill Yoder. The Cap 232 has always been one of my favorites, ever since I built a Great Planes .40 kit when I was 15, and totally destroyed it on the maiden, it was way out of my flying capabilities back then. So I have a couple Extreme Flight planes, and I absolutely love them, from assembly, to setup and power systems, those guys have got it figured out!

Recently I came across a halfway finished Cap 232 kit at my local hobby shop, exactly like the one I had at 15. I couldn’t resist it, I bought it and made it my winter project. So I understand completely why these planes aren’t popular anymore, with the tip stalling tendencies and whatnot. But I decided I’m going to do what I can to take that out. After some research, and some ideas from Extreme Flight, here is what I did:

-Lightened the wood skeleton
-Reinforced the control surfaces, wing, and various points with carbon fiber
-Made a removeable canopy hatch, very similar to Extreme’s design, since this was a nitro to electric conversion
-Made a battery tray
-Cowl from fiberglass specialties
-Switched from standard servos to high voltage minis
-Went from single aileron servo to duals, in the wing
-Moved elevator servo to tail
-Enlarged wing chord by 2 inches
-Enlarged ailerons
-Incorporated SFGs, stripped and recovered some from my 60 EF Laser
-Extreme Flight carbon fiber landing gear, wheels, pants, tail wheel, spinner, Blazing Star standoffs

Setup:

Xpwr 22cc
Airboss 80 ESC
4000mah 6s
2600mah 2s RX pack
Xoar 17×6 prop
Flex DS34HV servos

After all that, it balanced perfectly, I was amazed and super impressed! I have about 10 flights on it now, and I’m happy to say it flies awesome! BALLISTIC power! It does anything from KE spins, rifles, rolling harriers, both inverted and upright harriers are solid, crankshafts, blenders, parachutes, waterfalls and the whole nine yards. My plan was if it flies like crap, even if I don’t like gyros, to put an Aura in it, that way I can still putt it around and have it look it look nice. It does have still have the typical Cap tip stall going around turns at lower speeds, if I would do it over again, I would work on lengthening the tail moment. But the weird thing, in stalled out 3d flight, it never drops a wing! A modernized, 3D blast from the past!
