Mad Force

I bought a kit when they first came out. It had a GS .21, when it lost compression I bought a GX .21 for it. Now both need rebuild. Which one should I buy piston and sleeve for? Any and all suggestions welcome.

Thanks

send the piston/sleeves to rayaracing and have them repinched. It will freshen them right up.

I loved my MF with the GX-21... thought it was a top motor.

THanks for the info. The reason i posted this is because I think I read somewhere that kyosho switched to the GX in the rtr models because of issues with the GS that came in the early kits. Did anybody else read that?

Thanks,
