I find it a shame that most of the budget priced engines that should get the new flyer up and running have carb issues that dont lend them to be user friendly.
Therefore I see the low priced engines as "advanced tuner/flyer"(because not all flyers are good tuners LOL) engines.
Everyone seems bent on advising a new flyer to buy the biggest engine he can on his trainer. I do not subscribe to this. I feel they should get the most reliable engine with enough power to fly the plane efficiently. I just love the Thunder Tiger GP42 for a 40 size trainer.
So often I hear "you should get the biggest engine on your trainer because more power will get you out of trouble", my response is "only if you know how to apply it" unlike most newbies.
How about teach the beginner to fly the wing not the engine, they will be happier in the long run. considering my engine has dead sticked on me a few times and luckily I knew how to float er in.
