i woke up this morning and thought "nick the wing from a US Raptor" think it was because of that 45 degree tips thing, + my own TE sweep theorys.
you need this plane to be able to turn without loosing speed, its fast so you need to come back. Deltas have alot of drag in turns so i hear. fly it smmmmoooooooooooooooothhhhhhhhh.
our quickies do big U shape runs, one guy is always faster, main reason is he dosnt yank the plane over at the top and loose speed, he rolls slow, then pulls back so hes facing down same times as everyone else is just yanking over the top, and has the speed advantage right from the top. i've done this with my Dust on a much less fast set up, and i keep up by the time we're over the patch.
AKMacs plane is spot on, anyless span than that, and you'll torque roll too bad.
talking of high AR wings, there are powered gliders here, guess there too loo, brushless motors get them to height damn quick, then they dive. 120mph easy. its seams for small planes electric DF is the way to at the moment, 200 mph is acheivable. i've seen a 40 size DF Hawk with a 90, and it was 208 mph timed, i didnt notice it slowing down on climb either. The airframes top speed had been reached.
DF should be faster than prop, because props are like wings, they cause drag by turning, DF sits in a housing, and that acts like wingletts on the fan, so it can turn faster and give more thrust, thats the idea if you can do it anyway.i wantto try a MVVS 40 GRRT DF in a diamond dust type plane. might take a few of these ideas into the design.
