An unexpected park over at the Canterbury Aero Club on Friday the 24th was the Pitts S-2B ZK-STX (c/n 5090).
It has been sold to a Christchurch owner but is to return to Wanaka for the next year to continue aerobatic training on private operations on demand.
It still retains most of its decals, except for the "Southern Lakes Learn To Fly",
as seen at in the two pics below as taken at Wanaka on 23-11-2014,
