I have had my Vortex for about 3 years so it has been that long since I have look at the regs. I will check and verify that and let you know. As far as servos I am using Hitec HS255MG on ailerons,HS82MG's on elevators and Tower pro MG90S's on rudder. I was not too concerned about rudder because there are 2 of them and that make them redundant also I don't need them to fly the plane. I have also had very good luck with small Tower Pro and Turnigy MG servos, As far as electric brakes I have never used them, but that will change because I am building a FBjet's Viper jet and I think I will go with the pro link electric retract and brake set from Dream works. Do you know anything about that set. Places to find small brakes that I know are Tam jet, Hobby King, Robart, Dream works, I know there are others but this is what came to mind.
