The airframe and engine overhaul consists of a nose to tail total disassemble and checking. General overhaul information, and pictures of O/H facilities The airframe is corrosion proofed during manufacture by anodizing, and also etch/epoxy priming internally.

Instruments include standard flight and engine instruments in addition to the fully aerobatic horizon, magnetic slaved gyro compass and combined VSI/Turn and Slip. The slaved gyro compass is combined with a 8 channel, ground tunable ADF. The instruments are very good and are easy to use in IFR conditions. The aircraft is not airways equipped, having a single altimeter as standard. Most owners will fit a GPS.

Both cockpits have full duplication of instruments and controls, with the exception of gills control and manifold pressure gauge. The aircraft is flown solo from the front cockpit, the instructor occupies the rear seat. The rudder pedals are adjustable in both cockpits. The cockpit heating and ambient ventilation is very good in both cockpits. The aircraft was designed to operate in temperatures from -20°C to +40°C.

A 720 channel radio is fitted along with an intercom; the radio is compatible with David Clark headsets. The radio specifications exceed the requirements for western airlines. 0.001 frequency stability.
