RCbenchmark motor and propeller database

Our goal is to offer a community-driven database, where anyone can upload and share their test data, greatly reducing the trial-and-error process typically required to optimize the propulsion system of your UAVs.

252 electric propulsion systems tested

Public tests were uploaded with a total of 38087 data samples.


How to select the right propulsion system to maximize flight time


Longest flight time for a 5 inch propeller, with 1 kg of thrust

The longest UAV flight time is achieved by finding the most power efficient powertrain in the intended working conditions, while satisfying all the design criteria. The results below assume 5 inches propellers and a constant hover with a powertrain thrust of 1kgf, with no extra control authority. The first result is the most efficient one, yielding the longest flight time.

- 2.94 gf/W at 1 kgf thrust: DYS Samguk Wei HQ 5040
- 2.86 gf/W at 1 kgf thrust: DYS Samguk Wei Dal Cyclone 5040
- 2.81 gf/W at 1 kgf thrust: DYS Samguk Wei HQ 5043
- 2.78 gf/W at 1 kgf thrust: DYS Samguk Wei Dal Cyclone 5045
- 2.74 gf/W at 1 kgf thrust: DYS Samguk Wei HQ 5045

5 biggest propellers tested

When designing a drone or UAV propulsion system, the first step would be to pick the most efficient propeller capable of generating the required thrust. Then pick the most efficient motor in the same operating conditions as the propeller (same torque/speed).
