Default What is speed 400

Hi I have a plane that calls for speed 400 and after some research I assume it's an old brushed motor? What size brushless would I need to replace it? What kv rating? Plane is a cap 232 33" wanting all around 3d

You might get a better response trying in the "Electric Aircraft Universe" section just below the "RC Airplanes" section you are in. Someone there will be able to answer your question.

It's a brushed motor where the 400 is (I think) the length of the can in millimeters.

This will suit your needs, or you could pick another brand motor which would be similar in power.

http://www.wattflyer.com/forums/ If you were able to locate the Q&A then just a couple more down, the very bottom, is the electric forum. The reason no one gave you a reply was they didn't know. Larry gave you a perfect reply.

That power ten is about four times the power of a speed for can motor lol The Eflight park 380 inrunner is the closest motor or any inrunner of 20mm in Dia and of 35mm in length if want to run close to same size props. A park 300 with a bigger prop is more efficient as it spins a bigger prop. The Speed 400s were around 100 watt motors
