hey i have a problem finding a piston for my .15cxp smartech engine and i cant find a place that has those
thx

Don't bother to get parts bother to get parts for it. I don't think you can. My suggestion would be to get a new engine. This is a very good .15 for the price [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXFYN7&P=0].15[/link]. I have this engine it has a good rpm range,lots of power and easy to tune
