RE: Your countrys equvilant to the US AMA
In Sweden, where I live, the Swedish Civil Aviation Authority, [link=http://www.luftfartsstyrelsen.se/templates/LS_InfoSida_70_30____38148.aspx]Luftfartsstyrelsen[/link] is the governing body. They expect model flying activities to be conducted according to the rules of the Swedish Model Flying Association [link=http://www.modellflygforbund.se]Svenska Modellflygförbundet (SMFF)[/link], which is an association of Swedish model flying clubs that is recognised by the the world air sports federation, [link=http://www.fai.org/]FAI[/link].
In principle there is no requirement to be affiliated with SMFF to fly a model aircraft, but membership provides some benefits, e.g., a third-party insurance. For most people however, the householders' comprehensive insurance will provide sufficient coverage.
According to the regulations of SMFF, model flying can only be conducted from sites that are recognised as "model flying fields" by an affiliated club. That said, in a country slightly larger than California, but with only 9 million inhabitants, there is plenty of space for flying model aircraft so many people fly from any suitable field that they have nearby.
There is no radio license required to operate a R/C transmitter (most flying takes place on the 35 MHz band with the 2.4 GHz band becoming more popular by the day). The radio transmitter itself must be [link=http://en.wikipedia.org/wiki/CE_mark]CE marked.[/link]
As for the aircraft, the following applies:
Max weight with fuel: 25,0 Kg (55 lbs)
Max wing area: 500 dm2 (7750 sq.in)

Max engine capacity: 250 cm3 (15 cu.in.)
Max voltage for electric powered aircraft: 42 V
Max external diameter for the combustion chamber of pulse-jet engines: 82 mm (3 1/4 in.)
Pulse jet engines are only allowed for control-line aircraft
Max static thrust for jet turbines: 20 kP = 196 N (44 lbf)
Max sound level: 96 dB(A) @ 3 meters (10 ft).
