Hi all. I am looking at re-building a remote control boat I broke a while ago. I've never tried building remote control vehicle circuits so I need some advice. I was designing a simple transistor h-bridge to control the propellor motor/rudder servo but was not sure wether it would work or not. It will not need to last a long time because knowing me I will be re-building it again soon. Below is the circuit I have got so far but would it affectively control the motor/servo assuming the forward and backward control were from the same power supply? I can see no reason why it would not work however when I built it and tested it nothing happened.
