After rereading your original post I'd also be suspect of just that esc or that part of the 4 in 1 ESC had some MOSFETs or capacitors burn out or get knocked loose and so in high throttle situations when pulling a lot of amps to the motor it could be pooping out. To check if it's a given esc or...

Good way to get more info is activate and download the blackbox logs and use betaflight blackbox viewer app on your computer to see the input vs gyro info etc when it bails out. I've also heard of motor desync which this sounds like it could be but I'm not really sure what params to tweak in...

Yah that should be fine the only other thing I can think of is the esc doesn't expect the low to high range that the FC is sending it, are you using d-shot or pwm for the signal from the FC to the ESCs? In any case can try doing esc calibration also bench test with props off and using motors...

When you changes direction using bl heli suite which option did you pick? You don't want bidirectional in there that is for 3D flight, you want just regular normal or reverse options. Also alternative to switching settings in bl heli can just swap any two of the three phase wires (between esc...

Sounds like something is shorting out you can try to continuity check between GND and vcc when no power is applied but my guess is difficult or not worth repairing most likely. Hard to guess without hands on debugging and even then toss up on if I'd be able to find and/or fix the short. I've...

Are you able to connect in betaflight? What's it show the cpu utilization at in there?

Very likely this is normal. The battery is "7.4V" which means really it is two "3.7V nominal/average voltage" in series. A balance wire for a 2S battery only has 3 wires one on GND side one in between the cells and one after the second cell so it can measure and control current in or out of...

Note this did require me to replace the battery input with a male xt-30 to match up with the battery female xt-30

Can't really say the ones I got as extras are any better but they are about on par with the emax ones so far at least. I picked up some 2S tattu ones. Actually just searched and they have some HV ones (could be charged up to 4.35V per cell if your charger supports doing that)...

Honestly this is in the right ballpark, I'll get anywhere from 3-5 min depending on the particular battery and flight. Really they are best in light to no wind situations otherwise burning a lot of power just fighting the wind. Personally picked up like 4 extra 2S lipos and use a parallel...

There are cheapo ESCs that can kinda do the job but aren't nearly as configurable for various power input or controlling speed ramping or reading temp sensors and using HFI or other means of rotation sensing to avoid motor cogging at low speeds and other issues.

Yup I built an electric skateboard but ended up being like $700 or so even going "cheap" so not sure what to tell ya on the pricing there. Problem is the best esc for this kind of higher voltage stuff is arguably either the VESC or the o-drive, both are pretty pricey because the MOSFETs used...

:eek:o_O

@WaltDiesel hey ran out of room in the private messages length so pasting a response here also can get some other folks two cents if anyone has tried this. For context Walt is planning to make a 5 motor copter and my feedback below on why this might be problematic. If anyone has tried this or...

Hmm gotcha yah if changed the connector would maybe double check the solder on that make sure it is a good connection (not a possible cold solder get the whole bullet and wire going into it molten) maybe even over do it, as is you might have a high resistance connection that is bleeding off...

Another tip if not flying for a while discharge batteries to about 50%. If stored at 100% they lose life (imagine it is a balloon under pressure or a spring under load).

Maybe silly question but you make sure the new batteries were fully charged and are they the same exact ones that it came with in the first place? Also I don't have a bugs quad but does yours have brushed or brushless motors? If brushless the rotor (rotating can part on outside) will have air...

Thanks Eric!

Amazing views and nice edit per usual great work!

FAT32 is pretty typical since it is implemented/compatible with most systems but I believe has a 4GB limit on file sizes (this should be fine unless doing very long HD recordings). ExFAT is same as FAT32 but I believe increases the max file size but is supported by a lot of thing as well. NTFS...
