My Zac Project is a fully mod os12tr and pumps out 1.3hp.....yep, it goes!
The os12cvr is a pullstart side exhaust and also puts out 1hp, Ive seen one of these in a Toothless Tiger (sorry thunder tiger)
and it went pretty hard, i'd say very similar to the Novarossi.
When you look at the winners listings in magazines for nitro on-road you always see novarossi and some others (rb, picco etc) however I'm yet to see os in there, allthough they are frequently in the off road section.
Who said I was comparing the two O.S.'s with each other? I know which one would come out on top and so does everyone else
