servo advice raptor 30

[heliwilly]

just built raptor 30 kit, my question is; are the servo's that came with dx7, ds821, ok to use on everything except tail (probably use futaba 9254 or align 620 for this) also i have os37, but the throttle arm is not long enough, can i get an extension for this?
thanks for any advice. mike.

I'm not sure that many people consider the DS821 as suitable for any nitro heli, but I dare say there are some out there flying OK.

The critical servos on the Raptor are the tail (as you know) and the pitch, the rest are less critical.

Personally I'd prefer to use something like a Futaba S3152 for aileron, elevator and throttle, with a S9254 or the 620 for the tail and a 610 for the pitch.
