I have a son who lives on the other side of the country from me who just walked into a hobby shop and ordered the whole "package." He followed the directions and took the completed thing out to a local club field for help. The old pros there were amazed the at the thing started right up as set from the factory and as advertised. In fact, they were a bit frustrated to learn that it was designed to prevent their fiddling with the needle settings. He learned to fly on that airplane in a couple of weeks--never crashing it. The engine and prop are set very mildly for max "low gear" pulling and reliable running. He was impressed (and surprised). A single case does not a study make, however. Dzl
