You already know what it i$..
FWIW, their "improvement" no longer supplies a second frame,, only spars without springs..You are short one Leading edge and a whole $et of option$..

It also give them the opportunity to upsell a second frame separately.
Those are some very expensive Velcro, shrink wrap and paperclips.
