i8tweety,,,thansk for the reply. That's the engine I'm refering too. What is the average lifespan of the PiccoMaxx .26 and any noticable quirks? I hear about broken carbs when being replaced and bad front bearings. By the way,,,cool avatar,,,I got that one,lol. Between R/C's and building .22 ULTIMATES I dunno which one has more aftermarket parts.
