Definition of a Radio Controlled Aerobatic Power Model Aircraft
A model aircraft, but not a helicopter, which is aerodynamically manoeuvred in attitude, direction, and
altitude by a pilot on the ground using radio control. Variable thrust direction of the propulsion device(s) is
Radio equipment shall be of the open loop type (ie no electronic feedback from the model aircraft to the
ground except for the stipulations in Volume ABR B.11.2). Auto-pilot control utilising inertia, gravity or any
type of terrestrial reference is prohibited. Automatic control sequencing (pre-programming) or automatic
control timing devices are prohibited.
1. Control rate devices that are manually switched by the pilot.
2. Any type of button or lever, switch, or dial control that is initiated or activated and terminated by the competitor.
3. Manually operated switches or programmable options to couple and mix control functions.
1. Snap roll buttons with automatic timing mode.
2. Pre-programming devices to automatically perform a series of commands.
3. Auto-pilots or gyros for automatic wing levelling or other stabilisation of the model aircraft.
4. Automatic flight path guidance.
5. Propeller pitch change with automatic timing mode.
6. Any type of voice recognition system.
7. Conditions, switches, throttle curves, or any other mechanical or electronic device that will prevent
or limit sound level of the propulsion device during the sound/noise test.
8. Any type of learning function involving manoeuvre to manoeuvre or flight to flight analysis.
