Seven Belts
This photo gives you some idea what it's like inside. It's pretty bare and smells of AvGas, which, in fact, is what the black tank under the instrument panel contains. It's part of the system that keeps the engine running while inverted.

There are seven [!] belts .One over each shoulder, two for the lower lap harness, one for the crotch strap, and two for the upper lap harness. The upper lap belt actually has a winch, barely visible on the left side, for pulling the hips down against the seat. You strap everything down as tight as you can, then use the winch to tighten even further. Keeps you from floating around the cabin when you're inverted. Takes forever to get it all hooked up, but, if you need to get out in a hurry, you flip two levers and the whole harness explodes open. Also visible above the lap belts are the elevator trim lever and the fuel shutoff (red rod).
Instrument Panel
Small red button on top of the stick activates the transmitter section of the radio, aka Push To Talk
Out of sight above the pilot's left shoulder is the circuit breaker panel with light and magneto switches
Upper knob on the left cockpit wall (there's only one door) is throttle. Lower knob is Alternate Air. The engine is fuel injected so there's no need for carburetor heat, but there's still the possibility of the primary air intake and/or air filter icing over.
The separate throttle and RPM controls replace the single throttle control used in most trainers."Power" is torque times RPM. Torque is a function of manifold pressure which is controlled by the throttle. RPM is set by varying the pitch of the propeller. They take some getting used to.
The Alternate Air control can be used in emergencies to provide the engine with unfiltered air drawn from inside the cowling.
Magnetic compass is up on the glare shield, above the panel, concealed by the headphones.
Absent are Heading Indicator (gyrocompass) and Attitude Indicator (artificial horizon). Both depend on the rigidity of a gyroscope and would be too easily upset by the rapid attitude changes to be of much use.
The Turn Coordinator is also gyroscopic but depends on precession, not rigidity.
Panel right, under the registration number, are radio/GPS above, and transponder below.
Panel far right, mostly hidden by the frame tube, is the intercom squelch and volume control. Everybody wears headsets nowadays so communication with the other person is via the intercom. Much easier
than shouting over the engine.
Panel center upper row is airspeed, empty space and altimeter. Panel center lower row is tachometer with engine hour meter, turn coordinator and vertical speed indicator.
Panel center lower row is tachometer with engine hour meter, turn coordinator and vertical speed indicator.
Panel left upper row is oil temperature, oil pressure and G meter. The latter indicates current G force and has telltales to max maximums, both positive and negative.
Panel left lower row is manifold pressure and fuel pressure, cylinder head temperature, and ammeter.
The red knob is the mixture control, toggle switch is emergency fuel pump (used for starting), and the silver button is the starter.&nabs; Blue knob controls propeller pitch, and therefore RPM.
