Good looks but not tough enough!

Jun 23, 2017

Good looking propellers, but seem poorly built. I bought the "2mm 2 Blade CNC Folding Propeller Adapter CW & CCW (Titanium)" but the screw bolts it came with were larger than the holes in these props, so I had to ream out substantially. Then after fitting everything, the props simply turned out to be totally out of balance. Then I balances them out carefully, but still at lift-off throttle, they flex upwards and the quad simply doesn't take off. Guess only if they could make it stronger and with less flex, these would be great additions to DIY builds.
