A bit more
I hope not to sound like I’m an expert, far from it, only providing my experience
There was some discussion in forum that 679 is indentical 683s, reading you sentence seems as you replace 683s to 679, did you feel some difference? It can't be that moses released the same wing with different numbers as it's indentical. Where is reason to release it in such case? There must be something difference for sure. But nobody told clear what is difference:grigorib wrote: ↑Mon Oct 26, 2020 2:02 amLooking back at Moses line of 2020 I was lucky to enjoy three wings
- the 679 which replaced my 683s and was just as good
- the 695 which blown life back into my kite fuselage and made it rideable again at lower speeds
- the 800, introduced as windsurf race wing, it worked magic on kite fuselage and allowed even lower speeds than 695 while being more stable than 695 at high speeds.
I’ve had two 683s and two 679 wings in my hands, compared them both at home and on water. First of all, the original 633 and 683s wings were heavier wings, the foils with original 633 don’t float on the side. So original 683s was heavier by 70 grams compared to last year 683s.a99 wrote: ↑Mon Oct 26, 2020 4:31 pmThere was some discussion in forum that 679 is indentical 683s, reading you sentence seems as you replace 683s to 679, did you feel some difference?

There is very substantial differences between tech data of there wings in all parameters. So it's hard to understand why lot of people telling that they are indentical. And as 683s has higher aspect ration it must be faster speed, also even shorter shord. But as bigger 15cm2 probably is not role player for deminishing speed so much. Or?
When you see wing shape twisted so wingtips have lower AoA than profile at the root of the wing - that’s called washout. On airplanes it helps to keep outer portion of the wing flying when center starts stalling and that’s to keep ailerons located on outer portion of the wing stay effective and preserve control.
