Aberporth and Wet Through certainly were RAE, as were Llanbedr and Larkhill.
Then there were also operating airfields at places such as Pershore and Defford, which were RRE/RSRE - airfields supporting Malvern.
Along with A&AEE/A&AEE/DGT&E/DERA Boscombe Down, they are all one big happy QQ family now, of course. (Less Llanbedr).
I bet I've missed a couple of RAE outstations, too. Was Cobbett Hill one?
