I just put one together and I'm NOT impressed..
I hope the 415 is built better.Do you have to run the kit rims or did I miss something,I know Yokomo rims fit but none of my other rims fit.In the instructions I have It looked like the top plate fits on the front and rear bulkheads with no spacers or shims,the belt hits(rubs) on the top plate..
I can only hope it runs better than it went together.
