This would hold the servo in that position until failsafe kicks in, which may not have occurred. If you are moving in and out of valid signals the elevator may stay there until you release it and you might not have released it until the up-line.
Moving the RFU's antennas to be a bit more separated would be helpful, especially since you can create a scenario where the battery (any possibly motor) do fully block the signal.
When you landed, was the RFU or the X10+'s LED flashing? That would indicate a loss of power.
Jim,
Regrettably I did not look at the LED on the RFU or X10 after landing. Everything was working normally (of course). It would be nice to have black box logs on both the transmitter and the receiver to determine what my control inputs were and what controls were seen by the receiver and or output by the X10 during the perceived event.
I reckon that when the X10 loses a valid signal from the RFU, the two-second failsafe countdown begins. I also reckon that any new received good signal aborts the 2-second countdown. So you could have brief periods of controls getting blocked with some getting through.
I agree with your assessment that the signal was blocked and the system momentarily locked out while I was giving an up elevator command - that's an explanation that makes sense for what I experienced. I should be glad that it did not go into failsafe - if it did, and gave my incorrectly configured down elevator command, the airplane surely would have crashed.
I just factory reset the RFU and X10, and re-programmed them. I found that the RFU's default telemetry type is 1 = on, and not 3 = off as indicated in the documentation. It comes up as 1 after a factory reset (firmware v1.4). I do not want the telemetry signal on. Can you please verify that 3 is the correct setting if I do not want to use telemetry?
If 1 = on, then that means I had the telemetry signal on during my mysterious event - could that have made any difference?
Thanks,
Paul
