Your right, I have never flown anything other than a Slow Stick.
I'm not sure what your trying to say, but it doesn't mean that the only RC plane I have ever seen fly is a Slow Stick. That's absurd. I have seen quite a bit. Everything from .40 sized trainers to acrobatic helicopters, and just about everything in between. I still think, and this is MY opinion, that professional nitro sedan is a kick in the pants. If someone were to come up to me and ask if I wanted to spend my time watching the nationals in Santa Clara this summer or spend it watching the big annual national event for RC planes, I would go to Santa Clara, but that's me. Hell, I would go to both if I could!!!
Just because I own a slow stick doesn't mean I think the rc plane hobby is boring. I know that's not what your trying to say, but I have watched the Expert Nitro Sedans go at it on a professional level, and their skills are mind blowing. And I'm not so sure if it's a skill or a mix of skill and mind set. Watching acrobatic helio pilots I would have to say that they are even more amazing then the car guys. I would just rather watch a 8-12 cars going at it at speeds of 50-60mph (long track) for 30 minutes at a time with multiple pits stops. If you have never seen it, you might want to, at least on video. I'm sure at the end of the day, you will still consider planes your top pick, and of course, that's your decision.
