My 8ua from time to time loses model memory. I would suspect the built in li-ion batt. to be going bad, accept that it doesn't loose all the memories. just 1 here, 1 there. not using it now becouse I'm afraid it will reverse something in flight or worse. :stupid:

Hi flytlust,

The 8U transmitter does not use a lithium battery pack for memory. It sounds like something's wrong in the memory circuits. The transmitter should be sent to us for inspection/repair.

For information on sending this back, please see our site at:
