RE: how many enjoy the build?
There was a time that I had to demonstrate to a proficient R/C Pilot, that nothing was wrong with his SIG LT-40 Trainer, Rolling Circles and Rolling Figure Eights were just maneuvers that he could learn.
Here is My slightly modified SIG LT-40, with O.S. .70 Surpass II Four Stroke.
Built from Plans, Balsa Slab sides, 75" Span, Knock Around every-day flying model, 4 3/4 Pounds.
Macular Degeneration in both eyes, 21 Hypo shots into each eyeball so far, has slowed down my flying, but not my desire to build.
