I am having problems using the trainer feature on my hitec eclipse 7. When i plug the trainer cord into the eclipse and a laser 4 the servos go crazy so here is what i tried:
-Can plug trainer cord into eclipse but when i plug it into the laser servos go crazy
-with cord plugged as stated above once i pull the trainer toggle and send control to the laser 4 I can control the plane like normal
-with the laser 4 the master and eclipse the slave the plane works fine until i pull the trainer switch and than the servos go crazy
-have tried cord on two laser 4's and worked fine

this leads me to believe there is something wrong with the trainer circuit in the eclipse.
I know the eclipse trainer system worked before i reversed the battery accidentally. I sent it in and had it repiared. Could that be causing my problem. Is it posible the hitec techs missed it?
