The Slings is a lovely aeroplane, yes. Aircraft seems to handle totally normally. Checking out in one a few years ago, check pilot encourages me to pull harder over the top of a loop. Constant aural stall warning.
'No, Pull harder!'
Pull harder and very obvious buffet is felt.
'This time, pull harder!'
Flicked....obviously. Stopped within 1/4 turn. The aircraft communicates intentions well. We also abused it in various ways to provoke it but it doesn't actually bite without warning.
Problem is these common training aircraft are actually so docile that anything disguise the faults of pilots.
A good trainer is ghastly aeroplane.
Lots of adverse yaw, to show students what their feet are for.
Tailwheel to teach them how to land properly and crosswind techniques.
Obvious buffet and break at the stall. Healthy wingdrop on spin entry. (Condor was good as I recall.)
Please, the Bulldog and AA-5 are not in the same league. A clear case of British is best this one!
My ha'pen'th for TM. Go gliding and join your local UAS. Otherwise, if you don't want to listen to or clearly have no intention of accepting the advise you request-don't bother asking the question!
