Welsh3D,

DP recommends a minimum of 100oz for each aileron on my early version (one aileron servo per wing). However, the new version has two bays on each wing for ailerons, so he may have changed the minimum. Personnally, I would go with the strongest fastest servos i could afford. The airplane deserves these servos and will be capable of using every bit of the speed and torque. JMO.
