Specifications of the tested motors

 

Two motors have been tested, both are outrunner BLDC.

The first one is a N2830/13 from the brand EMP1. The second one is a LC2835-4T from the brand Leopard Hobby2.

The two motors have similar mass but differs by the Kv. The EMP motor has a low Kv which allows a slow RPM at the usual input voltage while the Leopard motor with its high Kv is meant for smaller propellers at higher RPM, more typical of a fast plane.

Below are the specifications of the two motors as they can be found on the companies website.
