Apparently I am not successful at sending the download as an attachment, is there a trick, I have the files, but they don’t show up.
Radio: Spectrum DX18, rx AR7010
Battery Turnigy 2200 3s
APM is 3DR
GPS and Mag is RCTimer
Machine is DJI F450
16V, 3300uf cap in system.
China man power module which works on others just fine.
APM, GPS, and Mag were used in rover previously without issue
MP 1.3.5, build 1.1.5260.33055
Being Spectrum, Channel ‘throttle’ goes to ch 3 input, signal only
Channel ‘aileron’ goes to ch 1 input on the APM, signal only
channel ‘elevator’ goes to ch 2 input on APM, signal only
channel ‘rudder’ goes to ch 4 input on APM signal only
Channel ‘aux1’ goes to ch 5 input on APM, signal only
spare channel on RX uses power and ground from APM input channel 8, no signal wire.
Voltage at RX is 5.22.
Have gone through setup 3 times reloading firmware each time. It does not always rewrite all the parameters from looking at the hdop parameters as I changed it in one try to 300 to get past a poor signal and it was still there on the next reload.
Regardless the problem has been during the wizard setup (and after if I skip the step) the machine will not arm even though all the above parameters are green and checked. The only times I have had success was when I went to the MP and armed the system by clicking on the tab for ‘actions’ and then ‘arm/disarm’.
One time by some strange thing, the machine was arming with the aileron/elevator stick in bottom right for 5 sec. I checked all the wires and they are as above, and that was the last time I got it to arm from the radio. It will not even do that since the last firmware upload.
At one point I was able to use the CLI and do a motor test, and all was correct.
I have another APM that is in a functional airplane. Going to take that out and try it as I see no reason for this not to work properly. I used the channel input data to verify I am getting signal into the APM BTW.
I hope this is enough info, and that the .log files uploaded.
