Head: If you like, the conversion to a Tempest 3D head is pretty easy. MA has a plan sheet online on their website. You need to order a flybar carrier, pitch arms, and a metal bell mixer kit. Get the rods, too. Grips and all associated bearings and so forth are the same. Get the one piece 90 D dampers.
Gear ratio: Order a gear ratio kit (the carbon plates) to yield 8.18 for an OS and 8.36 or 8.45 for a YS. You'll need a 90 tooth maingear and an 11 tooth pinion for 8.18 or an 11 tooth pinion and a 92 or 93 tooth main for 8.36/8.45. Get some shims to use as needed under the motor mounts.
Tail: You already have the gold standard parts.
