Servo torque
 

What is the min.torque needed for the throttle. I have a super tiger .51 that will be used and I was wondering if a micro servo could be used for the throttle.A few servos that I looked at had 16 -18oz.torque, mostly what I liked was the weight of the servo, I will be using a flex cable on the throttle. pub

I switched to a micro servo on the throttle recently for the same reason and it works out great. Instead of a 2-56 rod with or without a nyrod, I use about a .03 dia rod with a Z-bend on both ends and a V-bend in the middle for adjustment. With End Point Adjustment on the new radios this has worked out perfect for me. My engine is an OS 46 AX.

While the torque is adequate, the resistance to the vibration incurred with the larger glow engines may be marginal. There is a lot of vibration feedback on the throttle pushrod in some installations and I would worry about the gear trains in the mini servos.
