Aeromodelling is a fascinating hobby / sport with a myriad of interesting aspects from extremely light weight indoor flying models to very large models which may need a trailer for transportation.
Many aeromodellers will build models from scratch while others will build from kits and of course more recently "assemble" almost ready to fly models and yes ready to fly out of the box models are becoming ever more popular.
Along with the great variety of interesting aspects which the hobby / sport entails, is the end game of finishing and flying that model.
This is where the competitive minded modeller will possibly look to testing his or her skills against other like minded modellers and where the various FAI Sporting codes come into play.
These rules are set out by The Fédération Aéronautique Internationale Commission Internationale Aeromodelling which abbreviates to FAI CIAM To navigate to the FAI website or portal visit the documents page on this website for a direct authorised link to the FAI website.
Take some time to browse the FAI website and discover the many facets of competitive flight from models to full size.

F2 - Control Line

Control Line models have been on the go as far back as 1943 and subsequently in 1960 FAI/CIAM world championship competition began. With flight controlled by a pair of lines from a C or U shaped handle by the pilot in the centre of a circle.
The lines enter the model at the inside wingtip and close to the centre of gravity of the model a bell crank transfers motion via a link to the elevator and in some cases flaps.
Moving the handle up or down transfers movement to the elevator thus allowing the pilot in the centre of the circle to control the fight of the model which would be powered by a small diesel engine of the glo plug or compression ignition type.
For many years Control line was very popular and as a result many flavours of competition evolved.

These are the F2 Sporting Code control line Model headings.

F3 - Radio Control

Model radio control over the years has advanced enormously from very basic pushbutton to sophisticated proportional control with telemetry systems allowing an incredible degree of control over the aero model.
This Sporting Code covers a much greater area and is split into Aerobatics / Soaring / Helicopters and Pylon Racing.

F4 - Scale Models

Scale aeromodelling is typically the representation of an aeroplane in a smaller size, detailed closely or as accurately to the original as possible with the added dimension of flying in such a way as might be representative of the original aeroplane. Not for the feint hearted, scale modelling is for the fastidious and generally patient modeller with FAI Sporting Codes to cover control line, radio control, free flight, indoor and out door from the very small to the very large.

These are the F4 Sporting Code Scale Model headings.

F5 - Electric Flight

Electric flight models have become increasingly popular in past ten years due generally to advances in battery technology with power to weight advantages gained by the modern lithium polymer batteries. Alongside improvements in battery technology have been advances in electronic speed controllers combined with affordable pricing. The net result being clean quiet electric flight models we are all now familiar. Distinct advantages in electric flight model control are now clearly obvious over more conventional "ic engine" powered models.

These are the F5 Sporting Code Electric Flight Model headings.
