Yes that was me. I'm guessing it motor since that was the only variable I changed after the first run of the day. I just moved the timing from low hole to middle hole on a Duo 17.5. 2 bad speedo's later...I gave the motor to another guy at the to test and see what's wrong. Plan on getting a another one at a LHS so I have one to race with until the other 2 can be repaired. It's weird, both speedos can power the reciever and the servo but nothing lights up and both are not recognized by Hotwire.
