Congratulations to Flycatch for the first condenscending post in this thread and no, I'm not saying that because I don't value your opinion, its helpful. I say it because I can't remember the last time I had to control pitch or roll while driving and also because with the exception of race tracks, the VW Beetle and the Chevrolet Corvette in your example are both limited by the same traffic laws and speed limits. It's a poor comparison. Then there's the issue with comparing an eFlite Advance to a Corvette when a high wing trainer is a Beetle, it doesn't compute well seeing as the Advance won't be 3-4 times faster than the trainer in a straight line a la the Corvette vs. Beetle. We could even venture into handling too... the Advance will undoubtably have moderately precise handling along each of it's axis however, the Corvette isn't the first thing that comes to my mind when I think precision turning and handling. If I had to pick an American car to compare the Advance to it, I'd go with a muscle car (Mustang, Camaro, Challenger) although they don't have the most precise handling either so perhaps the best American vehicle that I can think to compare the Advance to would be the Ford Focus SVT - it's faster than the Beetle but not terribly so, has precise enough handling but not by Lotus standards and the cost is roughly equal.

That's my humble opinion but realistically I still feel that comparing RC planes to real world cars makes for poor examples.
