the ss is made by the same people who made the fantom and tamiya engines..they are NOT made my Novarossi(I think S&H made them)..regardless,it doesn't matter..
My SS engine is no way as fast as even my cvr side exhaust motor...I punted that motor in 2 weeks...
out a nice cvr 12 side exhaust motor in it..you don't want to go to fast,it will ruin the handling..
