RE: OS Vspec question.....here we go again
I'm pretty sure that this engine wasn't taken care of properly. For one thing, my engines are never dry inside. You have to run a good quality fuel and/or use a good after run oil to prevent dry starts. Friction=Wear. If an engine is well lubricated and kept within a safe temperature range, it lasts forever. RC "forever" is over 50 million rotations of the engine's cycle or 7+ gallons. I'll post some pictures of my Vspec and my RB S5 when I break them down this weekend, they both look polished on the inside
