Ah, ExAscoteer...the Tincano! Yes, a shame it needed a bigger engine to try to meet the RAF Spec. This in turn caused havoc with the Spin characteristics, and gave a period of busy employment to my FW colleagues at Boscombe Down. For my own famil flight (at Linton!) I recall a comfortable inverted spin but an uncomfortable and oscillatory erect spin. Anyway, ironic that it replaced 'the constant speed, variable noise' machine!
