Does the throttle work using the controller, if not then it could be that your reciever has broken or a connection has come loose. Speed_ace76, yea I was once new to RC but its a switch geeze, nothing special. Any switch will work, there are no special properties for different switches just get one from school (if you go to school) or a local electical shop, there like 50p each ($1 if your american)
