In my local club we fly mainly F3A pattern ship (a 2x2 meters, 5kg, 10cell),
Until recently I was the only one that use the open-tx (Taranis) on such big planes (Futaba & JR is mostly used)
But now another guy jump on the opex-tx wagon and fly his expensive plane with Taranis X9E
He use it with success for 3 month, but last week he had a very strange (and dangerous) problem.
He took off, and found out that he have limited control on ailerons, he succeeded to land (causing some damage to his plane)
When he checked the controls, he found out that both of the ailerons are moving slow & with delay!!
All the other control are working fine.
After turning the transmitter off & on, the problem disappeared, and did not reproduced again.
My question is:
* Did someone had this issue or something similar?
* Can someone have a theory to what is the problem be?
Configuration:
Plane: Tornado
Transmitter: Taranis X9E
Receiver: X8R
Telemetry: Two FLVSS LiPo Voltage Sensor (for the 10 cells)
Version: OpenTx version 2.1.8
Separate battery for receiver
Each servo (including the ailerons), has its own channel (no y cables)
His planes look like this one:
