Fittingly, it's a very early model: Mk I with aluminium frame.
Not the first alu-framed PP in the collection, as I already have a one with a yellow sail. Alu-framed PPs came in different versions, which can be told apart by the diameter of the aluminium rod. As far as I can tell, this blue Stunter is the same version as my yellow one. Nice thing about this blue one is new and unflown! So here it is in its maiden flight.
It was very happy up in the air, after having spent more than 40 years packaged up, waiting for the chance to take to the sky ... Flight characteristics are exactly as you would expect from an early alu-framed Stunter: very steerable as long as it has decent pressure on the sail.
Welcome to my collection, #50, and on to the next 50!
