Hi, im a new builder and have started work on a sig 1/6 scale clipped wing cub. Wingspan is 56" and im not sure which servos to use. The plan suggests installing a single servo in the fuselage to drive the ailerons via push rods and bellcranks however i'm reluctant to go down this route. I plan to embed one hitec hs-55 servo in each wing to eliminate control
slop but im unsure if the hs-55 has the muscle to do the job. In short, is there a method to calculate how much torque a servo should provide for a particular application? I picked the
hs-55 for the following reasons:

1. feather light
2. Wont put too much strain on the wing
3. Fits inside the wing with the control horn sticking out
4. No control slop

Any help welcome
