I can assure you, Centarus. It was an aerobat. Having said that, has anyone actually asked the difference between a garden variety 150/152 and an aerobat? The differences are not very structural. Heavier 4 point harness, d-ring releases on the door, special little caps on the battery and very slightly more robust l-brackets on the stabiliser.
AFAIK there are no extra bulkheads or heavier skin.
...and a g meter!
