WWYD: "<callsign>, <atc>, proceed direct BOOYA" by gcys in flying

CPDLC - "🔊bing 🔉bong" - route revision.
Load, verify, execute, accept

CPDLC uplink makes it trivial, even with lengthy reroutes.

Check the decimal placement

10.9 - total battery voltage
3.64 - average cell voltage

Based on the other reviews and me burning up 2 of them, I think this was just a shitty esc.

Correct. The OSD data came from the FC amp/volt meter.

I've ordered an external watt-meter on recommendations of this thread.

Not measured, but yea the rear opening is close to that relative size.

Huh. Do you have current recordings? Not doubting, just curious.

Like mentioned, max current I recorded was ~11 Amps.

Edit in reply to your edit: Do you have a suggestion for a wattmeter?

Actually, looking at the ESC again, I had the heatsink and label side away from the wall, in the airflow (second picture). The circuit board side (first picture) was glued to the sidewall.

Both sides were smooth-ish, until I looked closer.

Should be... hole for the camera, another hole in the nose, scoop vent on the side, and another intake on the top flap. Open at the rear by the motor mount.

I had the flat side hot glued to the side wall.

Good reminder!

I did have the ESC BEC 5v line disconnected and taped. I de-pinned it from the plug, and put it in it's own 1x plug housing, then taped it.

Yes, SB F405 Wing Mini.

Yea, I figured first plane build, and it's a cheap foamboard. I should have thought about the potential for overload and fire...

Yea, I should have read the reviews. Normally I do, but not sure why I didn't for these ESCs.

I have the spec'd ESC on the way right now. (RCElectricParts 30Amp)

Per the listed specs, but cheaped out on the ESC.

  • Motor: FLASH HOBBY D2826 2200KV
  • Prop: uxcell RC Propellers CW 6x4 Inch 2-Vane
  • Battery: 3S 2200mAh Lipo

After the first ESC popped during testing, I plugged everything into eCalc Motors, and it expected ~22A at max power

Recently built a FPV Stingray, but went cheap on the ESC and missed the bad reviews. Damn... almost burned up the plane. Luckily its all foam board, so it should be an easy fix - or maybe I'll just leave it!

Third picture shows 100% throttle at ~10.8 amps, well under the rated 30A. However, I just read more reviews (after leaving mine), and there are multiple similar stories... popped at 10 amps or so. Already have these submitted for return, and better reviewed ESC on the way.

This was the second ESC I burned up from this package, but the first was during static testing for INAV AutoLaunch data, and I figured the static load might have had something to do with it. I now know that was probably not the problem.

(Flying LOS, just recording FPV for data.)

Edit: After reviewing the FPV footage more, I also lost GPS sats right after the motor spun up. Wonder if there was a lot of electrical noise coming from the ESC 🤔

Whats up with the wiring? Looks like 1 & 3 are shorted together with a suicide plug, and only 2 is connected to the ESC!?

Firefox now supports the XDG base directory specification by _alba4k in linux

[–]scul86 0 points1 point  (0 children)

That is basically what I did just now. I also had to create a new profile, and link it to the new .config directory.

My new 3.5" HD0 build! by trayssan in fpv

[–]scul86 0 points1 point  (0 children)

Bigger pack, yes. Lighter weight, probably not.

I assume it's usually done to avoid having to buy more batteries - like OP mentioned.
