I have unmounted the board to calibrate it (accel) with high accuracy and replace previous tape by vibration damping tape
Could you re-watch my video in a previous post ? I really think that the noise at motor stop is strange (like when a hair dryer is stopping)
Hi, my friend, I am building a Tarot hexacopter 680mm with littlebee 30a (complete setup: motor rc timer 360kv; pixhawk 2.1; dragonlink v2; rfd 900; littlebee 30a; turnigy 9x radio; propellers 1355; lipo 6s 5.5a 60c gens ace).
I updated the esc (one by one) using an arduino nano, for now I only changed the parameter “Low RPM Power Protect” (the warning of danger is scary …). I’ll change the direction of the engine and fly.
I did not have this strange noise in the engine. I will post my feedback here as soon as I start the test flights.
test flights done… ?
When I test motors with mission planner (click on Motor A,B,… buttons)
The wrong motors are run :
1 --> 5
2 --> 1
3 --> 4
4 --> 6
5 --> 2
6 --> 3
Wiring is OK, SERVO function are OK (33 - 38)
Frame Type (Hexa,X) is selected (S550 frame=
Frame Type and class are correct in parameters tree :
Could you help me please ?
That’s correct. As it states on the MP Motor Test page “motors are tested in CW rotation starting with front right”. Front right on a Hex X is motor 5, then 1 and so on.
Test without propellers all is OK, I put propellers and go out, some motors (not all) start when I press safety switch (pixhawk disarmed).
Could you help me ?
Your throttle channel low end point is too high. You need to lower the end point, re-calibrate the radio in Mission Planner and then re-calibrate the ESCs.
I have change throttle channel min, recalibrate esc with mission planner and radio.
Motors seems to work fine, but I can see differences in throttlle range between escs
Its a problem… ?
Reading thru this entire thread the problem seems to be this craft hasn’t left the ground yet. Why don’t you try that and if there is a problem post a flight log.
First flight done, seems to fly good, but vibrations problems in log (wind day)

Do you think that vibrations are due to the wind ?
New flight, new log, same problem

In flight, I think that throttle is too smooth, should I increase climb sensivity or its baro alt or compass problem ?
Compass problem can cause vibrations problem ?

What problem? The vibration levels are not excessive. What I see is very poor tuning. Try an Auto Tune.
Ok thanks I will try, climb sensitivity problem in the image of my previous post… ?
Nothing to see there. Graph Dalt vs Alt. If they track it’s doing as commanded.
I remove the gimbal before doing autotune ?
Either remove it or lock it in place so it can’t move.
Yes, test flights done. All right, the Littlebee ESCs settings worked very well.
damped light on or off ?
