“We” lost a FPV brushless 2S 90mm micro quad (not mine) yesterday.
Standard E-90X frame, BR1103 8kKV, 1-2S 6A ESCs, Femto etc.
It even had a proper buzzer. What happened (or what we think happened):
The battery came loose and unplugged mid flight. No FPV feed from the quad, no buzzer, no DVR footage - bad situation. Albeit the area where we think it could be is rather small, we just could not find the machine (yet).
The connector in question was a standard 2S balance plug (used in order to save some weight) and it certainly wasn’t a hard crash. If you are flying a 2S+ brushless quad, I can not often enough recommend to use something like a XT30U.
Surely there are other “find lost quad” solutions than a buzzer (we have some good threads on the topic in this forum), but adding even more additional weight is sometimes just not an option.
Recommendations to save your day:
- XT30U on the quad side (compatible with all your XT30 batteries)
- Buzzer & ESC/Motor beacon (set to 1 min)
- Properly secure/mount your lipo, velcro alone is maybe not the best idea ever while rubber bands seem to work really well for lightweight 2S packs
- DVR (in case everything else fails e.g. water landing)
