However you are trying to equate it to a 3D YAK which is in a completely different catagory.
I was thinking more along the lines of an extra 300 setup for sports flying. I've had a thing for the extra 300 since my first time spectating at a flying field, which was back when 3D was for movies and video games. I wouldn't think the control surfaces on PTS mustang would be large enough for 3D manuevers...</p>
