Whirley Bird, That was back in 1980, When I had to do everything I could with an RC plane. The Skies were made from thin A/C ply and I used ammonia to curve the nose's,
It was fun and we had a blast doing it, My friend only crashed due to dead battery on trans.

Now I just build, I have a little helper and I take him to watch the planes, but at his age I wont fly and try to watch him too.

Sorry I missed this question, lost track of thread
