twin 90hp
I have as my long term project the restoration of twin 90hp Pobjoy powered Short s16 scion. At one time it was claimed to be "spritly" with 5 or 6 up and it did manage a 600 foot circuit when one engine died with only 4 up.
The aeroplane is still some time away from completion but this last year a milestone was reached with the first Pobjoy running. Prior to WW2 a total of 180 hp was considered quite a lot!
At any rate I must say I prefer the shapes and sounds of old aeroplanes.
