Compared to APC, much faster throttle response, quieter and improved downlines braking due to a quicker reduction in RPM when the brake is applied thanks to lower mass and moment of inertia.
Mejzlik EL Vs APC. Both 20 x 13.
Max static thrust. Mej: 9-9.3 kg. APC: 7.8-8.1 kg.
Max amps: Mej: 60.8. APC: 63.8
Max watts: Mej: 2402. APC: 2481
Max RPM: Mej: 6705. Apc: 6525.
Conclusion. Mejzlik provides more static thrust for less power consumption. Faster throttle response in both acceleration and braking. Trade off, increased cost and much more fragile.
Dynamic thrust tests are not possible, but based on the above I expect the Mej to outperform APC in this department too.
Testing conducted on a 50 cycle old 10s 5000 Giantpower pack which happily held 3.7 volts/cell under load. Logs obtained with a Castle ICE 2 80 HV controller. Static thrust with an electronic spring scale.
Overall: Very impressed! I will be promoting these results in the main UK publication which has over 30,000 readers
VS APC 20 x 13
Test results from 7-8 minute flights. 10s 5000 GiantPower 35C lipo, 53 cycle old
APC: 61.6 Amps, 2250 Watts, 6354 RPM
Mejzlik: 61.6 Amps, 2276 Watts, 6453 RPM
Mejzlik much quieter in the air
Thanks Mejzlik for your support! I will create a video soon with the propeller comparison.
The propeller go very weel, low noise and less ampere compare to other brand (PT model), very linear in throttle.
Last year i purchase the contradrive form Brenner (USA), next month i want compare your propeller, i will buy a set of 22x20 rear and 22x18 in front then i let you know the difference beetwen the brenner propeller.
