Hi Jason:
I had a Troublemaker, fixed gear, HP .61 in the early 80's. I didn't do anything at all to modify it and it was a very honest flying airplane. It always felt locked, didn't have any bad habits. One thing I discovered was that you could a nifty flat inverted spin for as long as you dared, with an instantaneous hands off recovery. Started it with a positive snap and a half from level upright and full throttle. You quickly push full down and cross the ailerons over and hang on. Absolutely fool proof entry and exit, full throttle the whole time. Not your standard fare for a pattern bird, but it was fun.

Have fun with yours. I also hope to build another one someday.
