My servos are JR 8411s, and they have 155oz of torque. I am running only one servo per aileron, but on the Edge that I am going to get, I will put 4 servos. The servos that I will use will probably be JR 9411s which are minis, but have 80 oz of troque a peice. Mine hovers very well at sea level. I think that as long as you keep the weight down, around 13 pounds since you say that you have seen a cap pull good at that weight, then you wil be fine. It should not be hard to keep it light. You can use a nylon motor mount, and maybe even Powerflites for batteries. Also since the new kits are lighter than the old ones, you shouldnt have a problem.
