Also there are Avro Ansons flying in Holland and New Zealand.
There was an Anson flying here last week, but it's based in England.

Its something to so with altering the stall / spin characteristics when the Tiger Moth carried dummy bombs under the wings in military service as a trainer. Can't give you the aerodynamic details, but thats the gist of it.
Wonderful aircraft, beautiful shots!
The Glider is a German SG-38 btw.
From the PPRuNe forum:
"Having read the relevant chapters of the Tiger Moth Story, apparently the Tiger passed its trials at Martlesham easily and its spinning characteristics were considered "well mannered". During the war, however, a number of aircraft were exhibiting a reluctance to recover form spins and some of the worst offenders were thoroughly tested at Boscombe Down (?). The worst once took 13 turns to recover! Yikes!
Apparently it was the only one with bomb racks fitted. It turned out that the reason was an increase in weight - three coats of paint as the training colours/camoflague schemes were amended, the addition of mass balance weights in the ailerons, plus bomb racks on certain aircraft... The <nobr>extra weight</nobr> in the wings acted like a fly-wheel... An impressed Tiger that had avoided the <nobr>weight gain</nobr> was also tested and confirmed the findings. The cure was to remove the aileron mass <nobr>balances</nobr> and to fit the anti-spin strakes mentioned in my post above.
Looking at the various pics in the book, post war some civillianised Tigers had the strakes removed (or hadn't been fitted with them) others didn't. Example is the famous Sea Tiger, G-AIVW, which certainly still sported them in the early sixties. I sohuld imagine that many of the aircraft that passed through Rollasons at Croydon were recovered in the course of their civillianisation, thus removing the problem."
