Query on the Woodstock

Australia determined way back when the glider first appeared that the
aft fuselage area had insufficient torsional strength and required
strengthening. ( I suspect that they were a bunch of *******)

looking through the articles that have appeared on the woodstock I see
that it has been flown with a self launch engine that popped up behind
the pilot. surely motor operation would have bought the glider undone
if it actually had any weakness.

what do you guys who actually fly the woodstock think of the
structural integrity of the design?
Is there anything about the design that you'd alter to improve it?
