I used hitec 85 mg in the wings. I would use no less for a 40 size plane on two ailerons. PDJ1...was you aileron servo stripped? Maybe that was the cause or part of it.
Would a regular servo fit there though ? seems like a dumb Q why would anyone fit another servo if it did ... but hey if you gotta ask ...ask

Thanks
