No power
Hi NickW
What Tx/Rx have you bought? What is the ESC?
Are you sure the original motors and ESC were working?
As this is a new Tx/Rx are you sure they are working? Are you sure they are actually bound?
If the lights were on the Rx and ESC the battery should have worked the rudder. NiCads are not good for holding their charge and are best charged just before using. NiMh batteries are much better in this respect.
