Brushless 1s whoop

Discussion

Hello,

since winter is coming, I decided to build some tinywhoop for boring and lazy winter days (and night) on dorm. My space is limited so less power is better. So far I gathered this: https://rotorbuilds.com/build/7133

Missing out on batteries (pref from bg), way to charge them (usb charger/para board/diy solution/whatever else), discussion on kv version (lower/higher?) and if the FC is worth it (I would like to have osd so I dont need to add buzzer).

Already have rx for it.

Thanks for any input

P.S. living in europe

The motors are probably fine. They suggest 12000kv but 15k will give you a bit more power, but the amp draw should still be under 4A. I think the FC is fine, it will give OSD and can run dshot and fast loop times. These batteries are probably fine. I'd get a parallel board to charge them since they are so small, its kinda a no brainer. I don't love the usb solutions since you can only get ~4W out of a usb3.0 port.

Well, I can always get lower kv, just wasnt sure about thrust:weight ratio. Found some guy flying with 15000 and it was super fast.

Interesting note for the usb, will look for some para board then. And unfortunately those batteries are out of stock. See what I can get in meantime.

Thanks for help

Higher kv will always give more power at the expense of increased amp draw. It looks like the 15000kv motors will still draw under 4A so you will not have a problem.
