I ordered another serious toy – really small and light camera (18g) for my small whoop, RC car and also XK A800 glider.
I get it from aliexpress with combination of coupons was for around 150$
It is 180° field of view camera where you can export 1080p video and you can rotate video in any direction without cropping and loose quality.
There really nice review on Oscar Liang web page.
As ussual if I get some new interesting part, i made a 3D model of it for later design of fixtures, holders and so on.
