Default ZIROLI CORSAIR ADVICE



I'm presently about a third way through a Ziroli Corsair build using a fiberglass fuselage with built up wings, stabs, and fin/rudder. My question is: If I use separate servos for each elevator, what would be the recommended average torque specs for the servos? I would like to put the servos in the horizontal stab, if possible but that limits me a bit due to servo size. I'll decide that later when I can do a better balance estimate. Engine will be a GT80. Thanks for the help!</p>

I've used this calculator and it seems to give useful results.

We flew planes that big back in the 80s with two standard servos on the tail, it was never a problem.  Or one giant scale servo with 100 ounces of thrust.  Now I use JR digital servos with five times the power, I think people worry too much about not having enough power on the servos but I think they really have mnore power than they really need by far.
