I agree with the previous post.
Make and model navigation would be good. When I scrolled down to look at a truggy that I own (Losi 8ight t), I didn't know which column was which I ended up having to write down the specs then scrolled back up to see what they were, Motor, pinion spur etc. Guys like to show off their rides too, maybe a photo gallery would be good , Sometimes I see a paint scheme that I like or see what a set of tires/wheels would look like on one of my RC's. I like the idea of what you are doing but right now it looks like the periodic table of elements.
