Thanks OG. The JS-1 self launch has been mentioned. Pardon my rudeness for "pinching" you but is the prototype flying?

Ben, I believe the inner wing weight is only a function of where the wing is cut (for the tips). The V2 and 29 inner wing panels are shorter than the JS, hence the lighter weight. Personally, I prefer the handling and ride of the 21m, but I am biassed to longer wings😄
