future ..there doesnt seem to be a direct replacement ...the only thing that will work is mr-ninja parts ...unfortunately they have all been bought up ...horizon scooped up all the parts that were left ...but unfortunately they are mostly parts people wont need ....you can find cases , o-rings, carb parts , and crank shafts still for sale here and there ...the really impportant stuff such as p/s and rods are long gone ...if any one needs a p/s for a tuned grp .21 that will also fit in a standard grp ...check the for sale thread i have one up there for sale n.i.p ....im not going to run them any more as parts arent available ...so i figured someon on rc tech might need it ....i wouldnt be surprised if a year or 2 down the road they pop up again ....its hard to keep those pesky italian down ...man they made a good motor ..sucks they are no more ..hope that helped
