3D wing loading
Hi guys..... who can tell me what the ideal wing loading for 3D flying is, on any model there must be a rule of thumb.... I know you can torque roll a P-51 if it's set up right
I've learnt about Power to weight ratios, large control surfaces etc, can you over power a 3D model???

RE: 3D wing loading
Well, how about a range of wing loading for 3D?
11oz foamy 3D at 380 sq in (2.64 sf) = 4.17 oz/sf
to
17 lb, 50cc class, scale aerobat, at 1365 sq in (9.48 sf) = 28.69 oz/sf
to
38 lb, 40% class, at 2400 sq in ?? (16.66 sf) = 36.48 oz/sf
anyone know what that 70% Staudacher weighs? and wing area?
Power: a little is ok, more is better, too much is just right!

That one? 350 lbs. dry. [X(]
I think the AMA would frown on that one at a sanctioned flyin.

RE: 3D wing loading
350 lbs!
Well, just gotta get a 720 lb thrust setup, howz about an IO-320?
Seriously, the wing loading desired for 3D aerobatics will depend on the Reynolds number that the model is operating in. A simplistic way of looking at it is that the larger the model is, the higher the wing loading can be and still fly like the lighter wing loading of the smaller models.
