About 12 months ago I had one of my most spectacular failures - this 92" Starship
It flew, but I couldn't get any roll control. It had ailerons, not elevons, and plenty of travel, but I couldn't steer it successfully and, on the second flight, we wiped out and spread a lot of depron over the next field. Probably I didn't take enough of the good advice I got from Don to be sure that the structure was rigid. I couldn't think of any other explanation.
So, what's the right thing to do with a smashed-up very big Starship?
Make it wait in the barn for a year and then take the best bits and make a very big Long EZ. I've used the outboard wing panels, adjusted them a little and this time I plan to cover them with glass cloth and Water Based Polyurethane.
What could possibly go wrong?
