New to the sport, and recently had a crash for unknown reason(s). I downloaded the logs from Mission Planner and tried to make out the logs, but having a hard time trying to understand the large amount of data.
Would anyone here be so kindly to help me understand what might have contributed to my crash. I can post the logs when requested.
Not sure what you are doing with the 2 notch filters, they are not configured correctly. Disable the 2nd one and set the 1st one with a Freg of 60Hz, BW at 30Hz and read up on the filter to set the throttle reference.
Thanks for reviewing the logs! After the crash, I assessed the the craft and it didn’t sustain any real damage. The battery tray did get yanked out and after reattaching, I plugged it back in and was able to arm it.
What would be the best way to test the motor and ECS? The prop on motor 2 is good shape as well.
MissionPlanner motor test.
Turn the prop over so it’s pushing down, set the percentage and time.
Only test that motor (or one at a time).
If you get this wrong the MP motor test can be very dangerous - best to take all other props off.
It’s unusual for a BLHELI ESC to lose sync, so there might be a overheating or connection problem.
Check that you have these settings in the ESCs using the BLHELI32 Suite, particularly
Low RPM Power Protect = OFF
Motor Timing = Auto
You might need to use another flight controller or Arduino to set them since you dont have DSHOT set up on this Cube.
With the Cube Orange it is relatively easy to set up DSHOT using the Aux connectors and get the BLEHLI data via a serial port. This would give RPM, temperature and voltage data for each ESC.
Or use the bi-directional DSHOT firmware and just get the RPM data without sacrificing a serial port.
Let us know if you want some help.
Definitely set this
You have 2 notch filters set up too, but not configured correctly.
INS_HNTCH_HMNCS,7 (EDIT, Dave said some this already)
There’s probably more we can help with, so start a new thread for your tuning and further discussions in that regard.
Getting back to the motor issue, the motor # 2 is bad after testing and comparing with the others.
I found some Tmotors as a possible replacement and would like your expertise please. Do you think I can use TMotor Antigravity MN4004 KV300 and a replacement? Thinking of doing all four. I hear great things, but not sure if they will work for the size of my drone.
Going from a 480kV motor to a 300kV motor with the same prop may not work. Plug everything into eCalc and see. It’s the best Insurance against “shit, I bought the wrong motors” And like everything T-Motor they are expensive.
