has anyone else had any of these n21r's breaking cranks. I have broken 2 one had 2-3 gal, and my last one just was broke in like 3/4 gal and they snapped crank from the nut out with clutch bell still attached to both, i,ve ran same exact setup with several motors and no problems ever!!! this is crap. Would it do me any good to try contact nova?? also does anyone have a turbo button for a p5 they would sell?
