If people are serious, and want to put in the time for a cheap affordable pattern, then I think its possible.
The next trend.....Hmm, so farm it is aiming at smaller wingspan, which will last a little while, then it'll go back to bigger. I do think that larger surfaces will happen soon though, don't know why, but I just think so. THe next thing after that, I suppose larger engines, as the planes are getting light enough to accept them. But, this is only what I think will happen.
