I've had my Summit since mid February. The original transmission servo didn't last through one battery. I picked up a second and it lasted about 6 trips out bashing...I recently converted my Summit to Brushless with the Castle MMM system and I reset ALL the endpoints on all the servos when I installed a Futaba 4PK radio system. The tranny servo again failed before the LVC kicked in on the first run. I put another one in and It died during its first run too. So, I lost the stock and two that I paid for. I finally called Traxxas and they suggested it was feedback from out of sync steering servos. I do have the Steering servos on a Y connector but centering and end-pointing them seemed to be breeze...I can't seem to figure this out. I have been doing RC for 15 years and I believe I know how to set endpoints. Anyone have any suggestions?
