I'm using 3003's on everthing on mine. I think I should upgrade the rudder servo but the rest are fine. Im runnin a saito 91with a 14/6 and the only time I run over 1/2 throttle is when I want to go straight up fast. You will will love this plane. I set mine up max throws and dialed in -50% expo. I Just leave it on high rates , no need to use low rates with the expo . I also set mine for 40% spoilers not flaps.
I can get her down in a hurry if I want ....kinda fun.
