What is the lightest DD motor that can handle around 3KW?
The Crystalyte HS3540 has been used to 3KW by the Stealth Fighter without any problems and weighs 16.4 lbs. The H3540 I guess is just a newer version of that motor? It weighs a bit less at 13.2 lbs. The H2540 weighs even less but these are not popular and I'm not sure how much less power it can handle.
I am planning to use ferrofluid with the motor to reduce heat. It will be used in a city with some hills so I expect a lot of low speed high torque starts which will make it run less efficient and hot.
I am also planning on using it with a sine-wave controller to minimize noise.
Mid-Drive using an Astroflight or similar motor would be maybe 3-5 pounds lighter but I don't like the noise.
