APM "2.8" fw 3.2.1 first flight issues

Quick Data Dump:

apm 2.8 with fw 3.2.1
ublox gps with mag
power from power module
900mhz telemetry radio
spektrum dx6 g2 radio

S500 frame ( dji flamewheel )

3s 3000 mah lipo battery
2212 920kv motors
30A esc with simonk firmware

here is my problem:

after assembling the quad it try’s to stabilize at a 20 Degree Bank angle ( flying to the right quite quickly.)
i could hold it in a hover but it took most of the roll input i could give it from the radio.

i have read the guides and searched the fourms and have not found any thing helpfull.

i was able to get a log file from my last flight
2017-06-05 12-38-16.bin (306.8 KB)

things i have done:

ESC Cal and spin up test. ( i have recalibrated all esc’s manually and using the auto method, i did not change the bank angle.)

full recal of accel and level. ( did not change anything, the IMU is aware that it is not level…)

full recal of RC system. ( did not change anything.)

checked for vibration. ( did not fine any large issues.)

Did the " hand hold" Test. ( found that the gyros are responding properly but it is actively trying to hold a 20 degree bank .)

Link to my build details.

Could you do another flight with increased logging levels?
RCout, mag, or just the lot.
Not a lot to go in that log file.

A screen shot of the HUD in Mission Planner?
From what your saying, the HUD should show a 20deg lean to the left.
Is that correct?
Doing an Accel calibration should fix that, multi axis or even just the single level calibration should fix it.
Unless something is wrong with your controller.

Where did the APM2.8 come from?
IS it an APM clone or a Pixhawk clone?

Mike,

i just got a chance to step out and try another flight with all the logging data enabled…

i also got a screen cap from mission planner

i purchased this APM 2.8 from amazon as part of a package.

i never thought it was a genuine APM, i just hoped that it would work correctly.

Your Aileron (roll) trim if it’s on chan 1 (RC1_TRIM) is suspect. Did you perform a radio calibration?

These APM 2.8 clones all seem to work well in my experience. I have used and retired (move to Pixhawk) several of them from different sources and they all worked fine.

i did not mention… i have remaped the rc channels.

i have a spectrum ar610 rx and it has the throttle as channel 1.

i feel stupid now…

after some more googling and tinkering i found that the rc input map and the output map are linked and if you remap one it messes with the other.

i have made a custom harness for my AR610 Rx to move the throttle to the correct location ( Default pins )

it has passed the hand test, now i just need the rain to stop to test fly it…

Let us know how you go.
Glad you found the problem.
