I just got my APM2 soldered and installed on my delta. My only problem is that the Elevon #1 servo doesn't response my controls. In any mode. It does move correctly in 'stabilize' when it is controlled by APM. But when I move my stick, only Elevon #2 moves. Any idea why this is happening?
Also, I would like to know what are all those jumpers for? JP1-JP4.
Nope. No continuity between ch1in and ch2in. :(
I guess I'll desolder the douther board and look where the ch 1 signal wire runs.
I just checked my own deltawing with APM 2 and everything works right. (I have elevon mode and CH1 elevon reverse checked). I suspect you've skipped some step in the setup, but can't think of which.
BTW, I'm not sure what CH 1 and CH 2 is reflecting in that status display. On mine, they're decoupled, even though my transmitter is in elevon mode (which should be coupling them at the RC side). It's a bit confusing...
It is confusing.
I followed these for setting things up. APM2RCSetup
Did you follow the elevon setup instructions?
What about those jumpers? I know JP1 needs to be ON to power the servos.
I presume the PPM Encoder is handling the inputs? Is there way to reset/reflash it?
You don't need to touch the solder/micro jumpers. They're just for advanced use such as bypassing the PPM encoder and using the serial port for something else.
I reflashed the PPM Encoder with Flip. No luck. Problem stays.
I did follow those Elevon setup instructions.
When you're doing the RC setup, do both the CH 1 and CH 2 bars move when you move either the elevator or aileron stick? If your RC TX is set up for elevon mode, they should move together.
The bars move together when the 'Elevons' option is ticked. Only ch2 when not ticked. So... was I fooled by that to think ch1 and ch2 were connected somehow. Maybe ch1 is not connected at all...
The input pin #1 (ch1) is not shorted and is connected to 220 ohm resistor. Also the 220 ohm resistor is soldered properly. What happens after that I don't know. It is too tight to fit my probes. :) Oh dear, do I really have to desolder the douther board(?)
Chris has located your problem , I had the same issue with my flying wing. You must enable the elevon mixing on the RC controller as if you were flying without an APM2 . Then you must re-do the RC calibration as the instructions and tick the elevon box as well. Note than when you do the calibration dont just move the elevator and aileron sticks to the normal up down, left right positions. you must move the stick to the CORNERS or the calibration will be wrong and the servos will try to move too far. this is because the elevator and airelon inputs are added when the stick is in the corner (full left and full up as an example)
Set the reversing switches so that the wing appears to auto level in FBW A mode and then reverse the Tx switches until the manual controls work the right way.... it took 3 trys before I got mine right!!!
Good point on the modified RC calibration process. I've added that to the wiki.
