The engine is rated for full power up to 15Kft...higher than I'd fly - don't plan to fly using oxygen, which is required up there. Someone a couple of years ago got one up over 28Kft, and that one has less power than mine (Rotax 914)!

The engine is the Rotax 915is. It's fuel injected, turbocharged with liquid cooled heads. So, it has three heat exchangers: coolant, oil, and air (intercooler for the turbo). There are actually two radiators in your circle - the larger, higher one is the coolant, the lower one behind and below it is the oil. The intercooler is below that bulge on the left rear top fuselage that ducts air to it.

Gyroplanes are weird sort of like an airplane, but also somewhat like a helicopter. Except to help prerotate the rotor, there's NO power to the rotor in turns and produces lift because of the movement resulting from the thrust of the engine, or the air going through it as you descend sort of like a, it's fully stable and safe when landing after an engine failure (which, you hope never occurs). Can't stall like a fixed wing, and is inherently stable in staying upright. Top speed on this one is 100Knots (about 115mph). It can fly as slow as 40 and maintain altitude (go slower, and you'll slowly start to descend), but is fully controllable down to 25mph, so it is very maneuverable. You need a runway to take off, but in an emergency, you can plant it without roll on landing, so you don't need much space. It's best at going low and slow...better to observe things.
