Your ECU needs to be hooked up to a receiver. (and transmitter)...that is where your throttle control comes into the picture. The safety switch is an emergency cutoff, also controlled from the transmitter. (most ECU's will not function if they cannot detect an active RC signal ...this is a safety feature)

I won't even ask what you are planning on doing with the turbines...BUT if they are not going in an airplane, you need to have a radio with a ground-use (ie non-aircraft) frequency..
