The stock gear and pinion should be fine for the OS .50 Hyper. For break in, let it idle a tank of gas, then let the engine cool with the piston all the way done (turn it slightly by hand with your starting wand). Then hover one tank very rich (two and a half turns out), and let it cool with the piston all the way down. Then slightly lean it and hover another tank. After that, do a few tanks of forward flight and lean another click or two, but keep a good smoke trail. Check your head temp on landing and don't go over 175 deg F or so and it should be OK. Once, it's broken in, you can go 1 1/2 to 1 3/4 turns and 200 deg.
