Harry,
hmmm! You've got me reconsidering now. Then again I have a friend who flies jets for Wren Turbines and he uses Hitec digitals all of the time. I just put a pair in an electric glider (nearly as expensive as a jet) and they are doing ok.
As you know normally I stick with Mpx for the whole system as this has never let me down in, now ,18 years. However, if the figures quoted for torque requirements are be believed, (a big if IMO) then I need some standard size servos with about 8-9kgs pull. Mpx currently don't have such a thing in their range, but the new Titan servos are Hitec built for Mpx rather than just badge engineered examples.
I guess I could put a pair of Profi V2's on the canard and fine tune program them, but the rudder is the issue. The recommendation is for JR 8411's. good servos but they won't live with 6volts which is what I use. What does that leave? Futaba; heaven forbid!
Or Volz perhaps, but I have heard some bad reports of these too.
What is a boy to do?
regards,

John.
