Expectations based on the shape
allright.. without having had one in hand yet.. Here is what I see..
Pretty small tip-chord (8-10cm maybe?)
the tip-chord is not Super small.. it's a semi general purpose plane for 'everybody' so it can't be to specific.. On the speed wings i've build myself I used a smaller tip-chord. That has a performance advantage, but it will allso make the plane a bit harder to fly.
pretty agressive sweep
again.. the sweep isn't Super agressive as it's suposed to be a 'everybody' plane but the sweep is definately more pronounced then in most wings.
This will do 3 things:
+ the pitch stability of the plane will be good (if the rest of the plane is well designed that is)
+ getting the CG right is easier because you can plane the lipo further forward
+ the base chord is longer then if the sweep wasn't this big -> more drag
motor (prop) pretty far behind the wing
just Excellent. The further away the prop is from the wings turbulance, the better.. Yes this Does make CG-ing a plane a bit harder, but from my testing I'd say this is definately wurth it.
on-wing vertical stabs
Okee.. so the vertical stabs are places ON the wing, rather then on the wing tips.. Having them on the wing tips Can lead to more (yaw) stability.. The setup Hk chose here is more 'unfortunate landing' resistant however
Here is by-the-way a video on one of my speed wings.. You can see a few of the things I mentioned above (small tip-chord + agressive sweep + prop far behind the wing)
All kinds of planes, multi rotors, heli's, cars & boats..
