What about dismountable motor with solder tabs ?
I have read that it's planned that you should be able to have some ROAR allowed motor for 2009 (I mean new rule). But racers didn't like sealed motor,
"We'll never have a ROAR legal motor. They're all copies of Novak's design. We're not willing to copy what we consider to be an inferior motor"
