RE: Heavy AT-6: Will it Fly?
Thanks for the input, guys.
After careful consideration, I've ordered a Brison 2.4 (39 cc) to replace the RCS 140. I think the
RCS 140 would provide marginal power and the Brison doesn't weigh much more and I can trade
power for lead. I almost used a Brison 2.4 from the start but figured the RCS 140 would fit into
the cowl better - and this it did.
Jai, I had to add 1.65 lbs of lead to the nose for balance. The split flaps turned out well but they
were a lot of work. I actually made new ribs for the sections containing the flaps. If I had it to
do over again, I think I would have made simple flaps that you would find on a P-51 or P-47.
These would be easier to construct. I used 1 servo on each flap and made the flaps from
1/16 ply with a hard balsa leading edge structure to hold the hinge points
