Our first 2.4 6ex appeared at the club site last week was range checked set up on a jupiter and flew a very impressive test flight.However....subsequent attempts to link the set to a 6exap via futaba buddy lead have proved completely fruitless the 6ex is the master, 6exap the slave. The slave fires up but command cannot be transferred via the trainer switch.Trainer funtion on the 6ex is enabled. Additionaly,the 6ex has managed to completely clear its memory of the model on the four occasions we have tried to set up the buddy box! Your views would be welcome before I speak to Ripmax on Monday.
