Doubt that. The wing root is just a handy place to put the battery.
There's plenty of room in the other root for an O2 bottle.


Doubt all you like ;-)

Max weight non-lifting parts is limiting on all of our 3x ASK-21s re max
pilot weight, not MAUW. I for one am happy for the extra 2 kg or so that we
can take officially. And yes, the extra space is great! Handbook says you
can take 10 kg of luggage in each wing too, which also is not of any
influence on cockpit load usually (or at least mostly isn't). Bit tight for
an extra cadet I would say, but it should see you through long flights with
plenty of bread & water on those long flights...
