Large Model Association

The Large Model Association (LMA) is a national aero-modelling body comprising members who specialise in the design and construction of large scale model aircraft.

The LMA was formed over 25 years ago and now has around 850 members.  It is recognised by the UK Civil Aviation Authority as the specialist body in the field of large model aircraft due to the unparalleled standards and safety record.

Shows and Fly-Ins

The LMA runs a number of successful shows and flyins throughout the UK as well as members visiting international events.

The shows are the LMA's showpiece events where the models are displayed to the public at a number of venues across the country.

For those who prefer a more relaxed time, the LMA also runs several fly-ins where the members can fly and mix with the other helpful and friendly modellers who are happy to help with the operation and understanding of large models.

The Journal

The LMA journal is distributed free to members bi-monthly and is full of interesting advice, reports and news.

Engines

Models use a variety of power sources from glo-plug, petrol and gas turbine with some pilots now using electric and turbo-prop power plants.

Multi-engine models are quite common these days taking advantage of the reliability of modern engines. The most common are petrol engines between 40-80cc but there are some engines of up to 350cc on the very largest planes.

Pilot Proficiency

The LMA runs its own Proficiency Scheme and pilots are able to get help, instruction and advice on how to achieve this distinction with our network of local examiners.

Models

All types of models are flown by LMA members ranging from simple semi-scale through to the most complex models.

Models are classified by weight with the smaller types weighing between 7kg and 20kg and larger ones in excess of 20kg.  Models weighing less than 20kg need no formal testing and certification before they can be flown and this is what the majority of members fly.

Over 20kg Models

Models weighing more than 20kg need to be inspected by an LMA examiner on behalf of the Civil Aviation Authority before they can fly.

The Inspection Scheme starts when the modeller registers the design with the Chief Examiner and Safety Officer who then appoints an Inspector.

The Inspector oversees the build of the model, checking various stages, right through to completion of flight testing.

After a successful flight test period the modeller is granted permission to fly their new model in public.  The scheme is free to members.
