Model aircraft with a mass of more than 25kg are termed large model aircraft. Within the UK, large model aircraft may be flown in accordance with an operational authorisation, issued by the CAA or under a permit issued by the Large Model Association (LMA).
Anyone wishing to build a large model aircraft should engage early with the LMA. The LMA operates a model inspection scheme, and once satisfied, will issue the required certificates and permit.
Model aircraft displays
Model aircraft operating in a display, must do so in accordance with the terms of the relevant Article 16 authorisation. Any model aircraft pilot wishing to participate in, or run, a display event should contact their relevant model aircraft association for further advice.
