Guys, I'm planning to maiden my N7 tomorrow. I paid particular attention to ensure the proper alignment of my clutch stack, and everything appears to spin freely and smoothly when turning the start shaft by hand. I can also spin the clutch bell by hand (main gear removed), and it spins freely without rubbing on the clutch liner. But when idling, the blades want to spin slowly (maybe one revolution every 3 seconds or so). Idle speed is good, but even at low rpm's, the clutch starts grabbing the liner. If I hold the blades with my hand to prevent them from spinning at idle, you start to smell the liner burning a little.
I have dropped and reinstalled the engine a couple times, and have triple checked the stack alignment, but no matter what I do, the blades spin at idle. I'm tempted to just go ahead and fly it a few times, and hopefully it will wear in just enough after a few flights. If that doesn't work, any suggestions on what to try next? Perhaps trying a new clutch or liner?
Barry
