This little high speed drone Japalura is just undestroyable and keeps place for a full sice camera.
It was a very good choice to take this 20x20mm tower (4 in 1 ESC 28A/ F4 FC/ VTX 25 to 200 MW).
The frame has not much place for electronics and this HGLRC XJB F428 & TX20 Flight Controller Stack
fits perfect. But keep in mint that this stack uses M2 screws and spacer, the Armattan frame have M3 mounting
holes. So i just use 4 M2 washer to fix the stack.
