I am using one of the new Hobby people Areosport 5's. It's a great radio but like i said the issue i'm having is due to no speed control of the servo at the moment until i get a new camera positioner. the one i have is an ealy version. the new ones are capable of handling more input voltage which i beleive was the problem. The first gen ones would just cook off from the higher voltage needed to run the High torque servos.
