D2 and D Motor Housing
Original motor housing for the model D2 and D Rainbow. This is for the non-bypass design that directs the air path through the armature and field.
The first version motor housing was smooth on the outside as in image two. This new revised version has cooling fins on the outside to help dissipate heat.
NOTE: Due to availability, you may get version one or version 2 as they are interchangeable.
