    15-20kw Brushless Motor Differences?

    What are the features that really set apart the brushless motors in the 15-20kw range such as the Hacker A200, Predator 37, Joby Motors, etc. Is it the Kv that makes a large difference? The Predator has a unique design that allows better cooling from spaces in the center of it, other than that I...

    What is the most cost effective RC brushless motor?

    What RC brushless motor would you say is the best deal in terms of how much power you're getting for what you pay? The Turnigy 80-100-B seems to give a lot of power/torque for only $100. Do any other notable rc brushless motors come to mind?

    RC motors vs Traditional E bike motors?

    I'm curious to what is an ultimately more desirable motor for e bike / e motorcycle applications? RC motors seem to be able to do anything that a low KV, higher pole count "traditional" e bike motor will do while being quite a bit lighter and even cheaper in some cases. From what I understand...
