im currently using a mach .26 pullstart in my savage. can anyone tell me where i can find a roto start backplate? i need it for the mach engine but it has to work for the savage, the shaft goes into the upper left hand corner. thanks...tim

I was going to tell you to to just order the roto start backing plate from horizion hobbies, but your savage starter unit would not work with it. Maybe check with ofna also.

you need this part http://www.horizonhobby.com/Shop/ByC...rodID=GSC89007 and the hpi, ofna, or hot bodies roto start will fit, but make sure you use the one way bearing that comes with the gs back plate

That pic is of a sportwerks .26 engine (same as mach) with the ofna roto start installed with the above backplate
