I use Hitec 5475's in a few of my planes but I did not opt to go with them on this plane. If you're going with only 2 servos for the ailerons I would chose a servo with higher torque. Yes they ailerons are small but there are 4 of them and the plane will come in at around 12lbs, thats quite a bit of mass. I'm going with 4 Futaba 9003 coreless sevos on mine.
