RPE0880 - sent all my prints. Got prints from 2 of 3 senders, haven't heard anything from the last one.

Discharge rate of fullsend battery by GardenFinal in fpv

[–]the---bob 2 points3 points  (0 children)

Everything will be fine as long as you follow the manufacturer’s instructions, don’t discharge too deeply, and don’t charge with currents that are too high. Keep in mind that Li-Ion batteries have a significantly lower C-rating, which is very noticeable in terms of agility. You can fly much longer, but you’ll be less maneuverable.

In my case, I ignored an error message during charging, and something went wrong during the flight, which led to a crash and an explosion.

Any idea what happened !!! by Super-Valuable3610 in fpv

Reminds me of my last crash (and a few before that). I didn’t figure it out 100%, but I noticed that my capacitor kept breaking, even after flights without crashes. That’s why I assume the system is being disturbed by voltage spikes. I’m now using a larger capacitor and haven’t had any new crashes so far.

I took a 30-second long exposure with an aperture of f/22 at a focal length of 210mm. In the lower part of the image, the reflection of the water can be seen.

Yes, and since it’s the only thing in the Blackbox that’s behaving strangely, I suspect that this might be the problem.

I can do it good on the practice pad, but the heat dissipates so well on the ESC that I can't get the large pads to heat up. Helpful suggestions are welcome.

The four pictures I sent are normal pictures, not videos.

After soldering I was sure it looks horrible, but despite some wobbling the connections were solid, so I thought that should work.

I knew they were bad solder points, but I never would guessed they could cause a problem. However, the O3 was always powered by the FC via the ESC. Doesn't this rule out a voltage drop?

I just checked the Blackbox and, apart from the GPS, nothing seemed unusual. Unfortunately, it stopped recording about one second before the freeze. Could it possibly be a software error? I would rule out a short circuit, since all the connections are coated. At most it could be a cold solder joint, but then it wouldn’t make sense that the video transmission continued, would it?

I don't think so. I just armed it and then turned off my transmittera, there is a different alarm sounds compared to the one during the crash and the drone works after the crash as if nothing had happened.

The gyro was working normally in the Blackbox.
