Sun n' Fun was an excellent show for homebuilt helicopters in 2000 (or was it 2001?).
Ultrasport had flying and static, 1-seat 254s and 2-seat 496s, plus a booth with cut-outs of various components.
Dennis Fetters had a static Mini 500, plus a booth with information and components used in the 1-seat Mini-500 and the developing 2-seat Talon.
In addition, there were other helicopters on display and flying.
Here is some of the 'reverse engineering' done on the transmission when Dennis left the booth for lunch.
