Don't stress too much about it. Follow the break-in instructions and later you can experiment with props for your type of flying.

In the beginning, the break-in prop will be fine for your trainer. VERY soon after you solo, you will want to scrap that engine for something bigger....and eventually move to gas.

After-run oil is for people who fly less than once every 3 months or so. It's a waste of money, time and effort. If you buy a year's worth of oil, you have likely paid for 2 OS .46 AX engines.

I put nearly 20 gallons through my MAGNUM .46, (a lower quality engine than OS), and could have gone much longer had I taped-in my crystal. Glow motors are just not very complicated. BUT keep your investment in glow to a minimum. Gas is FAR better, FAR cheaper, and the planes are FAR more capable.

GOOD LUCK!!
