Lots of folk are saying good things about the new Gemfan 5045 (5 x 4.5") bullnose props for 250-sized mini quadcopters. In this video I compare the GF offering to the widely used HQ propeller.
In a later video, I'll do some flying (somewhere!) and test the durability of these new Gemfan props. Apparently they're tough but I can break anything!
