ChasW,
I can give a big thumbs up for the Tower Trainer. My dad bought one with an OS 40 and was going to teach himself to fly with it. Unfortunately he passed away from prostate cancer before he got the chance to try. I decided I was going to learn to fly to honor him (and a lot because I have always wanted to fly RC). I took the plane to the local flying field and found somebody that would teach me to fly using an old MRC 6 channel radio (no buddy box here). The tower trainer was a very VERY good plane to learn on.

It's been 6 years since I learned and I have had a bunch of planes since then, but the tower is still hanging in my garage. I kept it mainly out of memory for my dad, but it's still flying. I use it as a trainer for teaching new fliers with. It got so bad that chucks of covering where coming off of it every time I flew it, so I recovered it in monokote and converted from wing mounting with rubber bands to using wing bolts. It's got over 200 flights on it and it still flies like a dream.

Just my 2 cents worth
