As I seen that these are with linear BEC so I am interested in one thing,can I connect 2 of them in the same receiver without eliminating a BEC of one of them?To clear things up*I have a foam jet that needs 7 servos and 6 are HXT 900 and 1 is Corona 929 mg for nose wheel steering so I want to be in a safe Amps by connecting both BEC's giving me a total of 6Amps.

It would be fantastic but sorry, it most probably will not work. What I do is use some y-lead powered not from the receiver but from the BEC that is NOT connected to the receiver.

The programming instructions are terrible almost impossible to understand. I want to setup for heli with 5 second delay and also soft start. Also what are the default settings from the factory?
