Thanks for that, Centaurus. I was on the 3rd last Winjeel course and there is no doubt that it was a better trainer than the CT4 that replaced it.
Amongst the numerous aircraft that were used for apprentice training at RSTT, RAAF Wagga in the 1970’s was a prototype Winjeel which had the vertical tailplane mounted further aft. The CAC changes to tail control surfaces to improve spin handling characteristics was obviously the reason why the production aircraft had the vertical tailplane mounted further forward.
