reminds me of swashdrive with a vertical motor. japanese motor? not too educated on those. i know the swiss knock it out of the park...ie. stigma, dragonfly (maxon motors). looks interesting and super lite. i like light, but the lighter they get the more i have to push on darker pigments and the ever feared elephant skinned humans. i wonder if the rca off the top would be annoying or actually help. HAIL TO THE ROTAR GODS! LOL
