That wouldn't surprise me at all, it would just be nice to know for sure. I found the trim line measurements and i think it's closest to a 190 but i really have no idea what I'm measuring for sure
Just measure the span and the chord in feet. Multiply those numbers to get the square footage. It won't be exact, but close enough to identify the size.
Or you can take a look at the V load tape in the right end cell and see what's printed there in ink.
The only thing i could find printed anywhere was the mfg date and serial number. I just got a reply back from aerodyne, they emailed the office in south Africa and confirmed that it is a 210.
