Agni PMDC - High efficiency

[reincarnate]

This company has been around for awhile but is still moving along at a slow pace to commercialization of their product. But all reviews I've heard are great. They get really high efficiency (~95%) and can achieve regen with an appropriate controller. They've got an amazing power to weight ratio. They are usually used for lower power applications like motorcycles, but they have a newer motor slated to come out in the fall that will be more powerful. Even with the lesser models, I think they will be plenty powerful for the XR3. It just won't be as high performance.

Can be used with this controller for Regen:

Otherwise should work with most DC controllers. The tech support guy at Jozztek is very helpful if you have questions.

Perhaps using multiple motors together may provide the required power. Maybe a combo of front and rear power.
