THROTTLE SERVO

[Bob Pastorello]

The servo is moving, yes, but it is moving WITH the motor, so there is 
little to no difference;  same with the pushrod.  You'll find the low 
throttle trim setting is a lot more constant, and doesn't 
drift....OBVIOUSLY - if there are ANY bad components in the servo, you will 
know VERY quickly.... but then just replace it and go on.  I've run 4 
different versions of this setup...it works, is reliable, repeatable, 
consistent.
