      The idea for EMRAX was born in 2005 when founder Roman Susnik flew Slovenia’s first flight in an electric aircraft. The flight ended in an emergency landing when the aircraft’s brushless motor failed, inspiring Susnik to develop a suitable motor himself. By 2008 a functional prototype was created and tested, and EMRAX had several requests for collaborations. Now in 2020, EMRAX engines are already used in a variety of electric gliders and aircraft. The motors possess a high power density and air-cooling, making them ideal for aviation applications. The performance figures for their largest model, the EMRAX 348, are summarized below.

          Do you know who might be able to supply 1105 or 1106 BLDC motors for slot car racing?

          They need to be > 15000kV, 0-12.7VDC, 1.5mm shaft.

          State of the art 1106 drone motors have high torque but top out at about 7000kV and are designed for say 3S LiPo power.

          Hi Rick,
          That’s a good question. Unfortunately there isn’t a simple answer, but figuring out what kind of motor/propeller performance you need is a good place to start. We have a series of articles that can help you figure that out. Start with this one and follow the links within the text for further explanation, that should help you get your answer:

          I want to build a electronic vtol quadcopter for one person with a weight capacity of 500lbs not including the flight assembly, question which motors can I use…..thanks


          January 26, 2023

          Great article! — The lift capacity depends so much on rotor diameter and pitch and propeller efficiency. There is really no point of specifying the “Max Weight” of a motor, without rotor specification.

          Best would be if you can provide an ideal formula that takes power, speed, diameter, pitch, prop efficiency and supplies the lift capacity. That is what engineers need. Thanks.
