My advice to all modellers is stall your model lots,<span style=''color: rgb(255, 0, 0);''>get used to where the elevator stick is when it stalls. Every time you put the stick in that position your model will stall</span>. If you find yourself turning final low and slow or making a tight turn and you notice that the Angle of Attack (elevator) stick is near the stall position then be aware that you are near the stall. Speed or angles (bank or climb or descent) are irrelevant.
Not quite 100% true in theory but close enough in practice.

The wisest words written in this thread, . Yes this was the most fundamental concept we would teach aerobatic students.. Your elevator is an angle of attack control device.. the wing always stalls at the same critical angle and therefore the elevator joystick (RC or fullsize) will be in the same position each time you stall.. if stall is encountered, you only need a few mm forward stick to unstall..
Very refreshing to see someone else say this.. Ahh.. New Zealander... Ex RNZAF?
Well I've
never been accused of being wise in here before, usually when I post something that doesn't match the accepted wisdom I get ignored, so thank you. And yes to both, you? RAAF?
I agree totally with your 'elevator is a (the?) angle of attack control device' concept but I wasn't allowed to call it the 'joy stick'. Sort of a 'this is my rifle, this is my gun, this is for shooting, this is for fun' argument for using correct terminology (military's funny like that).
My first flight with a civilian instructor included 30 minutes of basic stall instruction as part of the type rating (light twin) and then a demo of the recovery. When it was my turn I checked forward, increased power, and climbed away. 'What the hell was that' he yelled 'you'll re stall if you recover like that, you need to go for speed'.
I pointed out that if speed was the important thing then what was the point of the last 20 minutes (that I was paying for) demonstrating all the (angle of attack related) stall symptoms. And how would his recovery work at 300' turning finals from a circling approach, you guessed it his speed based recovery took 300', mine 30' (yeah I know but it was my first touch of the stick, sorry sir, control wheel).
To give him his due he did accept that he had been teaching it all wrong, especially after I showed him some accelerated stall recoveries (2G /60 bank, 90 bank and about 30 kts in a wing over). Doubt that he's been able to convince CAA to change the syllabus though.
Where do you teach aero's?
