So many choices for servos. How do you know whats best for your plane>?
Most planes have their recommendations for servos, but sometimes these
recommendations may be over kill and not clear on the torque and speed.

Is there a formula>? Some chart that explains which servo to use where>??

I have many planes , from hi wing trainers to large warbirds.
As you know. outfitting these planes with servos can get very expensive.
And I would like to minimize that expense.
So I only want to use the servo that is necessary and not overkill it with $$$.

Thanks for your input.
