What Was The Most Difficult Kit ?
Bill Robison.....my hat's off to you if you got the Joe Ott to the covering stage! My first rubber model was an Ace Whittman kit, the Zero. Didn't know to build the wings over the plan, so used the full length of the strip wood, and had a high altitude Zero with glider size wing span....actually glided pretty well!
Never built a Duelist, but flew one for a buddy years ago....his old K&B 40s wouldn't come up off idle together so takeoffs were an event!
One of the toughest builds I have done was the Der Jaeger, MAN plans, which were pretty poor. Many parts had to be measured off the airframe rather than the templates on the plans. It was cute though when I finally conquered it!
