Hi again

Are your using a y harness, If so you might want to change over to plugging them in to different channels. For example: mine are plugges in to channel 4 and 6. This depends on your radio. Anyway, this should allow you to have control of one aleron assuming if something happens to the other. This sometimes works and sometimes doesn't when you have a glitch

BTW, you need a computer radio for this

The other day you might of had control of one aleron and at least leveled the wing. Although your control would not be very good, you might have been able to safely land the plane.

Now, glitches are always anoying. I have had some pretty hefty ones with my electric heli. It is very common in electic planes an helis because of the motor and esc. I first try to isolate the glitch on the ground. Then i will eliminat things by unplugging each servo individually. Then if it is still doing it remove all servos and reoraganize them. You might narrow it down to a bad channel on your reciever, the whole reciever itself, bad servo/servos, bad batery, ect.
