Things a pilot should know but does it anyway. Pushing the plane back in it's spot by pushing on the spinner, low tire pressure will tear the valve stem off if you stand on the brakes and the tire slips on the rim. Too much oil fill to 8 qts in a 8 qt system, oil over the bottom of the plane. Bugs on the leading edge of the wings too much trouble to clean off will cost you 5 to 10 kts. The only time you have too much gas in when you are on fire so fill it to the top, we are just a little overweight and this plane if you can fit it in will fly. It's just a little frost on the wings. any other good ones.
