New Product Gemfan 5045 Bull Nose Props!



We didn't have a lot of time to put together an exhaustive test with real world data, but I did manage to throw them on my test stand and get you some basic numbers of how they stack up against other commonly available props!



At $0.75 a prop the Gemfans perform quite admirably (Compared to the $1.29 a prop for HQ Prop.) The Gemfan weigh in at 96% of the HQ Props thrust and draw 78% of the HQ Props amps! That's 4% less performance for a 20% gain in efficiency!



I can't wait to get these out and fly!

Testing Setup: Cobra 2204/28 2300KV Motor

20A ESC with BL Heli (See Screenshot)

Cleanflight

In cleanflight the range was set 1000-2000 and calibrated. Each prop was then tested and recorded at 1500 and 2000 throttle. When I moved to 6" props I added clamps to hold the test stand to my desk, because I didn't realize how much thrust they generated and my stand didn't stay put!
