Category F1 - Free Flight


This is a flight during which there exists no physical connection between the model aircraft and the competitor or his helper. Radio control functions are allowed only when specifically stated in the rules for the relevant class. Closed loop control systems with active sensors and operating aerodynamic flight controls are not allowed, except for steering in F1E.


Class:  (for beginner only)
F1A - GLIDERS
F1B - MODEL AIRCRAFT WITH EXTENSIBLE MOTORS “Wakefield”
F1C - POWER MODEL AIRCRAFT
F1D - INDOOR MODEL AIRCRAFT
F1E - GLIDERS WITH AUTOMATIC STEERING
F1G - MODEL AIRCRAFT WITH EXTENSIBLE MOTORS “Coupe d’Hiver”
F1H - GLIDERS
F1J - POWER MODEL AIRCRAFT
F1K - MODEL AIRCRAFT WITH CO2 ENGINES
F1L - INDOOR EZB MODEL AIRCRAFT
F1M - INDOOR BEGINNER’S CLASS
F1N - INDOOR HAND LAUNCH GLIDERS
F1P - POWER MODEL AIRCRAFT
F1Q - ELECTRIC POWER MODEL AIRCRAFT

 

Category F2 - Control Line Circular Flight


This is a flight during which the model aircraft is manoeuvred by control surfaces in attitude and altitude by the pilot on the ground by means of one or more inextensible wires or cables directly connected to the model aircraft. Devices in which the control wires or cables are held in the hand or connected to a central pivot may be used. No other means of controlling the model or the engine may be employed during the takeoff and flight except that exercised by the pilot through the line or lines.
Class:
F2A - SPEED MODEL AIRCRAFT
F2B - AEROBATIC MODEL AIRCRAFT
F2C - TEAM RACING MODEL AIRCRAFT
F2D - COMBAT MODEL AIRCRAFT
F2E - COMBAT MODEL AIRCRAFT WITH COMPRESSION IGNITION ENGINES
F2F - DIESEL PROFILE RACING MODEL AIRCRAFT

 

Category F3 - Radio Controlled Flight


This is a flight during which the model aircraft is manoeuvred by control surface(s) in attitude, direction and altitude by the pilot on the ground using radio control.
Class:
F3A - AEROBATIC POWER MODEL AIRCRAFT
F3B - THERMAL SOARING GLIDERS
F3C - HELICOPTERS
F3D - PYLON RACERS
F3F - SLOPE SOARING GLIDERS
F3G - MOTOR GLIDERS
F3H - SOARING CROSS COUNTRY RACING GLIDERS
F3I - AERO TOW SOARING GLIDERS
F3J - THERMAL DURATION GLIDERS
F3K - RADIO CONTROLLED HAND LAUNCHED GLIDERS
F3L - Re-assigned to F7 as F7A
F3M - LARGE MODEL AIRCRAFT
F3P - INDOOR AEROBATICS

 

Category F4 - Scale Model Aircraft


A scale model shall be a scaled down replica of a heavier-than-air man-carrying aircraft.
Class:
F4A - FREE FLIGHT FLYING SCALE MODEL AIRCRAFT
F4B - CONTROL LINE FLYING SCALE MODEL AIRCRAFT
F4C - RADIO CONTROLLED FLYING SCALE MODEL AIRCRAFT
F4D - FREE FLIGHT INDOOR SCALE MODEL AIRCRAFT; Extensible motors
F4E - FREE FLIGHT INDOOR SCALE MODEL AIRCRAFT; CO2 or electric motors
F4F - FREE FLIGHT INDOOR SCALE MODEL AIRCRAFT; Peanut formula

F6B - AEROMUSICALS
F6C - HELICOPTER ARTISTIC AEROBATICS
F6D - HAND THROWN GLIDERS

 

Category F7 - Radio controlled Lighter than Air


This category contains the following class:
Class:
F7A - HOT AIR BALLOONS

Category SM - SPACE MODEL


“Space Model” means an aeromodel that ascends into the air without the use of aerodynamic lifting forces against gravity; that is propelled by means of a space model engine; that includes a device for returning it safely to the ground in a condition to fly again; and that is made of substantially nonmetallic parts.
