Throttle cuts out

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.
