This is my latest DIY build, a super-compact foldable micro quad.
I got the idea to make my own custom foldable props, by cutting up some 6020 carbon props, trimming them down to 4.75 inches and using my RCX 1304 motor’s two mount holes (5mm spacing).
I had to dremel off the shaft from the motors, so that the props can move freely. I also made custom top mounts from carbon scrap, drilling two holes to match the 5mm spacing. Otherwise the M2 mounting bolts had too much waggle.
I also had to do a bit of prop balancing. The tolerances for vibes is super low with these folding props, so is important to get them well balanced.
The frame is a modified Diatone Blade 200. The rear arms are mounted about 6mm higher than the front, so they can overlap when folded. They are just held in place by friction. The bolts are pretty tight, and takes a fair amount of force to move them.
Am really happy with the performance. Some stats:
Dry weight: 114 grams
Take off weight: 160 grams
Battery: 950mAh, 2S
Flight time: 12 minutes
Vtx: 200mW, 5.8G
RX: Flysky, diversity antennas
