I am using one of these on my HK 300kv 20 gram motor. On 3s it draws 2.9 amps and 35 watts. Which is enough to power my 1.5m powered glider. 9 oz AUW.

This is the first folding prop on my motor glider and it really helps the gliding when power is off. Glad i purchased them.

They are OK for what you pay and they do rotate reverse, meaning your motor will have to rotate clockwise, seen from the front. They have a 2mm centre hole and a hole of 2.4mm diameter on each side. I guess these can be centre holes if you want to cut a thread for the 3mm grub screw, that is part of the package.
I just wonder if there is a matching counter clock wise rotating prop available?

Okay, they're cheap. They're flimsy, but I was expecting that.



One thing they're not is counter rotating, in the normal sense of the term. That would mean one of the pair spins one way, and one spins the other. These are pusher props - both of them. I.e. if you put them on the front of a plane, they would have to spin clockwise, not counter clockwise as seen from the front, to pull the plane forwards.



Most people don't bother to buy pusher props because a conventional prop works fine as a pusher. I assumed these were a counter rotating pair, based on the product title. Provided you want two reverse pitched props, they're fine for what they are.
