Whats up yall. So there will be profanity in this post. If you have small children have them look away now.
I am on my last wit here. If this cannot get fixed, I will post a video of me blowing up this f*****g quad in some shape or form. All work Flawlessly and the issue came out of absolute nowhere.
So............. New Motors, New ESC's, ALL new wiring. Only the bare essentials connected. Reinstalled Pixhawk firmware. Re-Flashed pixhawk. Re-Flashed Devo Transmitter. Tested quad with pre-arm off. Re calibration of pixhawk. Tried again. Removed power module. Powering pixhawk with 5v leads from ESC's.
The quad cannot leave the ground......It seems as if the quad is EXTREMELY under powered. When at full throttle, the thing runs for a few more seconds, then a full blackout. I mean FULL blackout. ESC's, Flight Controller. even with the battery connected. To power back on, The battery needs to be unplugged and plugged back in again.
PLEASE PLEASE PLEASE PLEASE PLEASE help.....................................for god's f*****g sake.
P.S. I intended on using more profanity.....
Check your THR Max parameter, I have had an issue when i had just flashed new software and it was set to 100 (which means 10%) and fixed it by changing it to 1000 (100%). Doesn't help with the brownout though, assuming you are using only one and not all of the esc's to power it because that can cause issues depending on the type of bec in the esc.
1- Try a firmware rollback. Helped me once, and that is an easy way to verify that your mechanicals are working.
2- Try re-calibrating your radio. EzUHF gave me fits for a while.
3- As listed elsewhere: check Throttle MIN, MAX, and MID.
4- Tell us what worked.
Can we get ANY data of your quad??picture?video?Anythng...
Sorry yall. I'm still having the issue, just been troubleshooting this thing left and right. It's looking like something is actually wrong with the Pixhawk....
@Checkers, I haven't tried that fix yet and will when i get home and let you know how it goes.
Here is a video of the issue at hand.
My guess is a power issue / ground loop somewhere.
Somehow you're trying to pull power through the pixhawk or BEC and it's tripping (there is a resettable fuse in the Pixhawk).
How have you wired the ESCs and BEC in? (If any bec).
Do you have Signal + ground going down to ESCs from Pixhawk.
The BEC signal and ground are connected to the pixhawk, I clipped the 5v leads so they are no longer connected to the pixhawk, The pixhawk is being powered from the power module. Where is this reset-able fuse you speak of?
So try the ESC signal wire without the grounds? And what do you mean by shunt?
@Crispin, "I suspect he's realised that he's a fool and won't be back."
Your comment is harsh, please consider removing it.
I have to keep the props on. This only happens when props are attached. If i disconnect one motor (Any), the issue doesn't happen. Already sliced my hand open xD
