I too found my setup perfect.....until I switched to digital servos. JR811s These things are sick! Centering is like 1%. I did like it just as much with the Hitechs 405s which I think are now discontinued. I still have the Hitech 645 on rudder in a pull/pull configuration and as soon as my hobbyfund recooperates I will switch that out to digital as well. Can't see the difference untll they are side by side. They are much quicker and crisp!!!!!! Saito 100 is the way to go. Lighter than the OS 91 with a lot more bang. 15/6 prop, CG at 5 5/8" You will love this plane. It lands like a Senior Kadet, which should be illegal.
BigNed, check this out, slooooow pass, high rate ailerons and bang em in the middle of the pass. Even at slow speeds this will out roll anything out there. Joe
