Well I finally just ordered a set of S9202 coreless BB servos. Not digital, but after considering everything brought up here, I feel digitals would be overkill for this plane. They seem to be better suited for 3D and helicopters. Plus the issue of power draw was unnerving. I still torn between a 6v Nicad, or a LiPo pack with regulator from Fromoco or Duralite.
