In the mid 1960s at 631 GS RAF Sealand I think we had an equal number of T31s and T21s (3 of each ?). Although I did most of my gliding and first solo in the Sedbergh, I don't recall my size being a factor. I was average height and weight ..... and like to think that I still am!
During my time at 631 I also flew the Mk3, including some solos.
