S pena que quase nunca tem outras cores disponveis.I think the blades a little thin. But they are good. I had to use a drill to widen because pro mistakenly bought the propellers. These propellers are to be used with nuts. I use the adapters propellers.No estan mal para el precio que tienen, pero las he tenido que taladrar todas, el orificio central es pequeo para el eje de algunos motoresSo far these have been great. I mounted them on my Quadcopter using the D2822/14 Brushless 1450kv Outrunner, and it hovers stable around 1/2 throttle. The motors came with prop adapters that were too big for these props, but I reamed it out and it threads right on to the shaft. They required a little balancing, but they flew well without it. Love them!Not very well balanced (the same problem with others GWS-like props), but packaging tape helps to balance it well. At least, my pack cannot be balanced by just sanding heavier blade (same applies to 11x4.7 GWS-like pack), tape is needed (or You end by having one very thin blade).
Hole is ~2.5mm, can be mounted on 3mm shaft with little force.
Not too strong - hit grass or something stronger, and they will break, but at such price - get 3x props needed, balance them all at once, replace when needed.Good flexible propeller for Quad copter ,can take some abuse .The perfect prop for the Turnigy L2205-1350 Brushless Motor. Brilliant efficiency, most of them are balanced and much quieter too then other slow fly prop I've tried.
