trex 600 nitro crash

something gave way on the cyclic and it came on down. update the crapy step down unit that had only 2 flights had broke when u touched it the electrics would cut out then go back on . the next flight didnt fair much better i used a 6 v batt direct into receiver and it went flat after a min of use and crashed, i am back on the original align unit now with the switch repaired so 3rd time lucky eh!
