That's just 1 manufacturer. There are several popular manufacturers now as well as several varients such as turbo prop versions & those used for helicopters. We have many choices in heli's too. Here's one from way back when I first started covering the local events. Rotor span is 10 feet. It had issues at the event & wouldn't stay running which came down to a defective glow plug (the complete heli was new & this was the fist time any of us saw it.). I made arrangements with the owner that once he had if fixed & flying to PLEASE phone me so I could photograph it in the sky. I got the call a day or 2 later & rushed over to the club he belongs to which fortunately is a 2 Km drive from home.
awesome looking copter, some of these guys should get together with an airshow event and do some displays there
