On full run up test, motors shut off and throttle display goes blank. Release the throttle, display returns and motors power up. Any idea abut how to resolve. I found no similar condition in the forum.
That is very odd. I almost wonder if there is a short somewhere. Are you able to turn your motors at all with any throttle level?
Open the throttle casing, mine had a similar prob. I had to re sotter the power cable it was off and problem solved.
