There are six Technical Committees who control the model classes in the UK.

They are as follows:-

FREE FLIGHT – Look after all free flight models that fly outdoors with the exception of Scale. They also look after Magnetically Steered models. 

CONTROL LINE – Look after all classes of models flown on the end of a set of control wires, with the exception of Scale.

RADIO CONTROLLED SILENT FLIGHT- Look after all classes of models controlled by radio that are either gliders or powered by electric motors.

SCALE - Look after all classes of scale models.

INDOOR - Look after all classes of free flight models flown indoors, with the exception of Scale.

Additionally MODEL ROCKETRY is controlled by the Competition Secretary and covers all the Space model classes. All the above classes have various competitions and flying events run both locally and nationally, with most types having classes that have European and World Championships run under the auspices of the Federation Aeronautic International (FAI).
