Model Aeroway grounds

I am trying to map some model aircraft flying areas and unsure what tags to use for the area. These are not areas shared with others in public parks but are large areas set aside for very active model aircraft clubs for their recreation.
I expected that the bounds of the area could be tagged with
landuse=recreation_ground + aeroway=model_aerodrome or sport=model_aerodrome
aeroway=model_runway for defined/mown_grass/marked runways or aeroway=model_airstrip for more general runway area
ref=02/20;14/32 for runway orientation

Proposed features/Model Aerodrome

Aeroways

Would like further advice and comments or a good example of a well mapped/tagged model aerodrome thanks.
