Servos?

Hi
I need some help. I dont know how big of servos I need to build this B 29. It has a 169 inch wingspan.
The flaps are about 28 inch`s long, I have four on the wing, two on each side. the plan calls for one servo each, the elevator is 51 inch`s and it calls for one servo. the rudder is 20 inch`s, one servo. I sure could use some help Rick

If you want you can use these and all you will need is one on each surface..
Or you can go the digital route and over spend. Bigger servos + bigger gears = more strength. For that size plane I would go with the large servos.

Yes they do. But don`t worry you may get a flood of replies telling you to use digital servos at 2x and 3x the cost. I`m surprise they are not posting yet...
