RE: YIKES!!! Crashed by DPS today
All I have ever used are standard ball bearing servos. Futaba 3004's and Hitec HS425's.
I have built seven DPS's, three 40 sized, two 60 sized, one with a Roybi 31 gasser and a 40 size twin.
I learned about tapering the ailerons on the SPAD site and have never had a problem with flutter.
