Hi, We're new to the RC World (my son and I). He has purchased his first RC plane, assembled it and now when he connects the battery he only gets beeping from the plane. I've spent a couple of hours looking for a solution on line without any luck. Best suggestion appeared to be setting the throttle limits but can't work out how to do this on our controller (Turnigy 9X - does allow setting limits on the flaps). Can anyone help us please? Mr Bill
