Axial .32 ???'S
 

I have an Axial .32 RR-1 and it needs a new piston and sleeve. I would like to down size it .28 if posible but I hav noticed the case number for this model seems to be specific to the RR-1 though I noted Axial says it is based of the 28 RR. Does anyone know if it can be converted?

I plan on using this in ofna buggy so I don't need all the displacement and would prefer to have a smaller motor that gets better MPG.
