I had a similar interest in R/C sailing this past winter and posted the same request. I was steared toward the Soling 1M. I could not be happier with the suggetion and now my neighbor and I frequently can be found on the pond having a grand time. Beleive it or not, I have found sailing much more of a challenge and more fun than the nitro boats I have been running the past 5 years.
The Soling 1M is fairly easy to build, has a tremendous following and support network and has great sailing charcteristics.

I wish you the best on your jouney
