Here is my DIY wing collection along with the stock MHL wing set. Top DIY foil is best by far using the stock tail wing. It is fast and very docile, drives with front foot almost like a surfboard.. Second DIY foil showed promise but delaminated during a high speed broad reach. It was a little too twitchy to be fun. Third DIY foil is super fast a little unstable but fun to ride. It hums at high speed so it will not last long before it comes apart. The small DIY tail foil was a bust. Too small. All main foild with DIY tail foil felt very sensitive to pitch.
Next step is to build a slightly larger tail foil with vertical winglets and a refined main foil like the Top DIY foil. Slightly thinner wing thickness. Slightly wider center section. Slightly narrower wings outboard of center section. More washout on wing tips.
great wings dlprince69!!
when you mean 7% root is because you used half of the eppler 817 profile?
what i mean is if you used the upper half of the wing with a camber and a flat bottom (asimetrical).
questions to fórum colaborators:
1.if wings and fuselaje are more succeptible to impact or damage, wouldnt kevlar outer Shell or kevlar/carbón hybrid cloth make a better material to use as final finish layer?
2.as general rule what is the average front wing root?
3. what about the root of rear wing?
Ok today i was bored as hell so wipped up this high AR wing as another test.
took me an hour to make profile and cut the pattern.
tomorrow ill vaccum bagit.
