I have yet to loose a servo on the throttle on any of my gas or glow planes due to vibration, unless the engine was mounted on rubber or comes loose the servo is going to move just as much as the engine will and if the end points are adjusted correctly theres no pressure at either end point there shouldn't be any issues. I keep my throttle servo as close as possible to the carb. I do agree that a digital MG servo would be a good investment for obvious reasons. But 333 oz of torque is not only overkill it also adds more weight to the plane. Whats next a sailwench servo ?????
The Hitec 7955tg list its stall torque or holding torque, the true torque as tested by TBM is only 248oz/in. Thats why I would just go with the HD-9150's they list 220oz/in, and put out 224oz/in More bang for your buck![8D]
I would think it would be hard to strip a servo from vibrations... when I first started with gassers I ran regular Futaba 3004 servos on my throttles and they did the job.
I think that depends on what voltage you are useing dont you?
I have used more standard servos for the throttle than I care to remember and never once had one fail, like you said it all depends on how well you set your planes up.
Hey Joe here ya go, its a little slow but it has plenty of power
