SSD. That's a great shot of your machine. Lovely.
Got a good few hours in both the 52, and a 50, which I had a share in whilst owning my Chippie.
For all that the YAKS had the power, I still loved the Chipmunk, even yearning to get back flying, after stepping out of a YAK flight.
Has yours still got the thumb prints embedded in the back cockpit shelf???
