It may sound stupid(and I know you aren't a rookie), but make sure the rx lead is properly oriented in the receiver(though with Futaba style plugs you really can't screw it up, the warrior has a generic style "fit anywhere" plug). You may have to try the reversing of the throttle channel as well.
on the receiver plug for the controller, which color is positive, which is negative and which is signal? i just want to check as my friend is bringing over his m8 and jr radios to test.
thank you for all the help
