It is probably too far and too expensive, but there is space in our hangar at Biggin Hill. Plus the person that runs our hangar at Biggin Hill is an expert at looking after Austers as he has two. Romford to Biggin is about 45 mins by car, as this is the time it used to take me from Purley to Thurrock when I kept a Robin there and the distance is similar. Actually have you considered Thurrock ?
