I am not sure about the nitro motors, but they do have a product line for pipes and fittings.
Fantom is still doing their custom line of brushed motors and can do just about any combination you want. They have stepped into the brushless scene and have more motors on the way. And finally they are doing the EnerG 4600 packs.
I foresee some good things coming out of the Fantom camp this season.
