VERY cool Andy,
Between you and Grob we'll have to change that Heaven/Hell joke to British Engineers.....being heaven.
I think this looks like a blast to play with. Wish I had the time and patience to build something from scratch. I'm very envious.
One question: How is the mast attached to the front beam? Hard to tell from the photo. Seems like a high torque area.

Congratulations!!

Greg
