I've been using 10x4.5 props on my quad copter, which is quite heavy, and it works pretty well, just about 50 to 60pcnt throttle to hover. I tried these 11x4.5 props, and my quad would not even lift off at well over 80pcnt throttle. I took them off immediately. Not happy with them at all.

Very brittle, very hard to balance

ABSOLUTELY AWFUL PROPELLERS!

Keith says it well in the comments:
''The pitch angle is positive near the root, then goes negative near the tips! This is a terrible design and sacrifices a LOT of performance.''

Basically half the propeller is pushing air one way, the other half is fighting against it and pushing the other way. A good propeller should push the air in the same direction along the whole plane of the blade. These do not.

HobbyKing sell plenty of other propellers that are decent, unfortunately these are not one of them.

Here's what a prop should look like:

AVOID THESE PROPS, they are massively flawed.

These props are way too heavy........I've run other 11" props fine on my tricopter DT750 3S but wanted something a bit more rigid....these heavy props drain my lipo in about 5 mins or less and barely gets off the ground with full throttle.....whereas I was getting 12 to 15 minutes on other 11" plastic props.

I bought 2 packs of these props and they are really awful. HK should have controlled these before selling them. These are manufactured NOT correctly. They are thick, rough, heavy and give absolutely NO LIFT!! Now I want to return them.

Im not sure of all the designations but these had less lift than than the 10x4.5 SF plastic props. I know these are 1045E. Not sure what the E is. My quad lifted at 45pcnt throttle on 1045sf plastic. It needed about 55pcnt to lift off with these. Maybe the designation is the cause for a bigger prop with same pitch to need more throttle
