Hi Randy;
Just picked up a ST.51 (recent version) that is the R/C version and was wondering if you have any C/L cylinder liners to convert it for stunt use? I have to dig out a parts sheet listing but I think I remember the only difference between the R/C and C/L versions is the venturi/needle valve and the cylinder liner. A good used one will do I guess also. Tower shows them as "order pending" but we know what that can mean! This engine I have is new and never been run.
Thanks a lot,
Dan McEntee
