I read SOME of the comments on the thread that Gordon pointed out in the above link.

I think the stiffness of flying wing/aileron, the quality of the hinges and push rod and the HOLDING torque of the servo all are to be considered. Having said that, I never could understand how come the IMAC guys use FOUR 8411 on their rudders and their planes are not going more than a 100mph? I know the rudder is huge, but the speeds at full deflection are modest.

Are we OVER buying torque in our jets? IS there a false mind set that we need 8411 on EACH flying surface for the Bandits out there?

Then again, the "reliability" of a more expensive high end servo is PRECIEVED to be better, but is it really better?

May be the Hitec 5645 digi is a great buy for around $56 to be used anywhere in our jets.....Just wondering!!
