Flew my Goldberg Cub a few weeks ago and took her out this morning. When I hooked everything up and turned on the radio, the ailerons immediately went full 'left'. All other surfaces were o.k. Trim checked 'center'-no apparent trim dialed in. Fiddled with it a bit and wound up taking the servo arm off and moved it to center, and readjusted the rods. Is this enough info to give me an idea if I've suddenly developed a radio, or receiver problem? I did try turning the radio/Rx on and off a couple of times. It flew o.k. for awhile, but I'm leary. Haven't checked my other planes. I have a Pac, and about 8 or 9 planes dialed into the radio(some of which are U/C and don't have all servos hooked up) and have never had a problem, though my battery is only charging to 10.8V. Any thoughts? Bill S.

If something spontaneously changed, we'd not know why unless we can see the transmitter. Even so, it may operate normally. It is possible that there's a bad memory chip inside the unit, but is acting intermittently. It's also possible that the programming was accidentally disturbed, and nothing's wrong.

A 10.8V reading is normal. The transmitter would be considered nearly discharged when it gets down to about 9.4V or lower.
