Yes, thats right, there will be surface hardened steel bevel gears available this month, for all our elevated tail series. The setup fails easily with a quad head, as by lowering N2 rpms to almost the half, the tail shaft drive has to cope with almost the double amount of torque. This upgrade will consist of a total of 6 bevel gears, as we found that the original align bevel gears will fail too, no just the two in the 140deg box, but also the two ninety deg bevels on the tail rotor shaft and the 2nd stage gear. The set will also include new shafts, shim washers and installation hardware. Will keep you posted.
