DarwinFPV F4019-2 Folding Propeller

Summary

The DarwinFPV F4019-2 folding propeller is an upgrade based on the Gemfan Floppy Proppy 4019-2 propeller.
We abandoned GEMFAN's original plastic propeller clamp and used a high-precision stainless steel bushing with a carbon fiber propeller clamp to control the accuracy to ±0.05mm. It vibrates less, is lighter, and is more resistant to explosions than the original propeller. It is difficult to feel the difference from an ordinary two-blade propeller.

Features 

1: Folding design, easy to carry when going out;
2: The carbon fiber propeller clamp is stronger, explosion-resistant and safer than the original Gemfan plastic propeller clamp;
3: The control accuracy of the high-precision stainless steel bushing is ±0.05mm, which is higher than the original Gemfan plastic propeller clamp. No jitter, no paddle washing, super smooth;
