very nice 20mm stack from flywoo! nice quality!
Excellent build quality, compact, well packaged, flies great so far. But be careful, the VTX power input takes +5V - I didn't read carefully enough, connected it to the +9V "VTX power out" on the FC board, and let the smoke out (only fried the VTX I believe). My own fault but rather annoying still.
Flywoo should really provide a battery cable and xt30 connector with this stack. Kind of a minimum standard today and really annoying if you don't have one in the spares. You get M3 and M2 mounting material, even though I have never seen a frame with M3 20x20. That's always M2, isn't it?
Excellent stack 20x20
one of the best mini stacks
