Lynx Heli Ultra Tail Shaft CNC Pulley Assembly
Almost everything Lynx makes is fantastic, both in terms of quality and design. Unfortunately, the cogged pulley on this tail shaft is slightly flawed. In short, it EATS tail belts! I believe this is because the cogs on the pulley are machined with sharp teeth when compared to the stock plastic pulley. The sharp cogs gradually scrape away material from the teeth on the rubber tail belt as it passes over. I've tried a couple different Lynx tail shafts and I've tried varying the level belt tension to try and reduce the problem to no avail... I still get fine rubber shavings all over the tail case in inside the tail boom. Once I went back to a stock plastic pulley the problem immediately disappeared. Sadly, this is one of the few parts on my 450X I've had to keep stock instead of using a Lynx part.)
