After reading a many posts about " junk engines" - " glow plugs" - " transition problems" and many more I feel the best first thing to learn ishow to set up YOUR engine, carburetor, and proper size prop. In order to learn to be a good pilot one must have an engine that will run and keep on running no mater what attitude the plane is in. ( Barring a prop strike). (NOTE) every engine is different. You don't need to think about the engine quitting while you are trying to think about what you should be doing next.
