I have been flying RC for 40 years, and got fed up with the "bigger and more expensive is better" attitude that I found pervaded our flying field. After bouncing around the indoor guys fgor a while, I bought a couple of Stealths, and they are a blast.
Check out this link for more people using them.

There are some QC problems, but they are solvable, and people are starting to modify these for some real performance. They are not "proportional control," and you need a decent sized field to fly one, but they are incredibly rugged.
Good luck, and let me know how you do.
