OS .12 RC10gt

[OS4ever]

So i have an rc10gt with an OS .12. It needs to be rebuild, piston and sleeve. Does anyone on this site do resizing themselves or am I better off buying a rebuild kit?

I have another RC10gt with an OS.18 on it and I am about to break it in, the .12 is sooo fast it doesn't even grab traction, so i may have bit off more than i can chew with the .18

I desperately need to get the .12 back on the road.

much help needed.

thanks

Don't really know of anyone here that does it, but I've had Ray at www.rayaracing.com do three for me last winter. Two of them ran great all summer long and still run great. The third is sitting on a shelf as a backup engine at my buddies house.

You can take a look at my before and afters here:

so do I pull apart the piston and sleeve, or send the whole motor. If the sleeve is tighened back up wont there be alittle room where it goes into the motor, or is still a tigh fit?

From looking at his website, I am definitely going to send 2 of my motors off for a pinch!!!

Just send him the piston/sleeve only, with con-rod attached is ok. I mark the piston top and sleeve with a marker by putting a solid line from the piston to the sleeve so he knows the orientation of it in the engine. Not sure if it matters though. He normally cleans the tops of the pistons off to remove the carbon buildup as well.
