hv is cutting out

first of all apparently my biggest problem with the HV is that i own two of these turds! I called the tech line today and as usual they were polite and realy tried to be helpfull but didnt realy have any cures for my ills.they suggested undoing the red signal wire and see if that helped, it didnt initialize,then i left the red wire off and rigged the rx pack turned on the tx,plugged in the rx pack and flipped the switch and it fired right up and ran for about 3min.its a shame cause ive had such great luck with my GT7, four plus years and then on too brushless for over two year with a GTB and never had any probs with them.Im done and thanks again for the ideas
