"Lots"? Hardly. For every one who made it there are probably 100 or more who gave up after several rounds of fly, crash, repair or replace. Every one of these threads follows the same pattern, a few say they learned with no crashes and a few say they did it with several crashes. Once a few have posted this they attempt to make it sound like everyone can learn on their own. They appear to block out the fact that many try and fail or finally seek help after wasting time and $ going it alone. I wonder why these people are so intent on encouraging beginners to follow this much more difficult, and expensive, path to learning?
