Very nice propellers. Actually surprisingly big ones! Ordered 2 pairs (for a quadcopter), from wich one pair was indentical. Hobbyking has refunded me for the mismatched pair and didnt have to send back the "wrong" pair. VERY good customer support!!

They break too quickly - or is it my lack of skill? Other than that they're fun and quiet.

Great prop for a light quad during the learning stages. Seem to be strong enough to reliably fly a 2 lb 450mm size quad but fragile enough to break in a crash and not bend a motor shaft.
