I have a Super Stinker with a ST3250 in it. I was going to use JR 821 all around then came this thought. Are they strong enough? or the 3250 will vibrate them apart?
Should i go to a metal gear servos? Any thoughts would be appreciated.
Thanks, Phil

Rabbid fly,

What is the torque spec of a JR 821?

The 821 are about 75oz torque. Phil

Phil,
According to the construction manual, you may want to consider 100oz for the rudder. All others should be fine.
