- Does anybody have experience flying indoor R/C? I'm curious about what wing
- loadings would be reasonable for flying in a 55 x 25 meter (180 x 82 ft)
- gym.
-
- In one reference I've seen, they recommend an upper limit of 0.122 g/cm^2
- (4 oz/ft^2) for wing loading. An IMS indoor contest in 1980 had an upper
- limit of 0.0915 g/cm^2 (3 oz/ft^2).
-
- Those limits seem a bit low to me. For the larger wing loading, a 30 degree
- bank and coefficient of lift of 1.0 that gives you a turn radius of only 4
- meters. Airspeed is 4.8 meters/sec. I would think you could get away with a
- larger turn radius, although it's hard to say without actually trying it, I
- guess.
-
- Is that reasonable? Or is my coefficient of lift to optimistic? Any
- comments?
-
- I've tried to use a Microsoft flight simulator to get a feel for the
- problem, but I haven't had much luck setting up the simulator properly.
