Thanks Hoss,
The easiest way to understand stalling and recovery is to understand that your Elevator joystick is effectively an angle of attack control. The more back stick you apply, the greater the angle of attack will be on your wing.
Example below -
With neutral elevator stick assume your wing has 3 degrees angle of attack (normal for level flight) and full elevator deflection results in 23 degrees angle of attack.
Call neutral elevator position (0%) and full back elevator (100%)
Moving your elevator stick from neutral to full back results in a 20 degree angle of attack change. (so every 10% movement of the stick gives you 2 degrees angle of attack change)
If you move the stick 50% (half way) you have 10 degrees more angle of attack.
Assume our wing stalls at 18 degrees. (The stall angle of a wing is a fixed value and is independent of speed)
Now compare different Elevator stick positions (%) to the Angle of attack it generates (degrees)
0% = 3 degrees - unstalled
25% = 8 degrees - unstalled
50% = 13 degrees - unstalled
70% = 17 degrees - unstalled
75% =18 degrees - stall
80% = 19 degrees - stall
100% = 23 degrees -stall
Following this logic, you can see that every time you apply more than 75% elevator, your aircraft will stall. Relaxing the stick by just 5% will unstall the wing.
An aircraft will not stall by itself. The pilot is the one who makes the aircraft stall by using too much elevator.
These numbers are simplified for this example and will vary for your aircraft. The exact stick position to generate a stall in your aircraft depends on factors such as CG, mechanical throws of your servo / linkages and also the design of the aircraft, factors such as flap setting, prop wash / thrust setting etc will also change this position slightly.
But the basic concept is true for all aircraft. Your joystick controls the angle of attack. Pull too much elevator and you will stall.
To answer your original question Pete, your ARF Bandit may stall with the elevator stick at 90% deflection, but your balsa Bandit for reasons listed, may stall with only 60% stick deflection.
If you have been flying the ARF and using 65-70% elevator without stalling, then you fly the Balsa Bandit with the same inputs it will stall.
You develop short term muscle memory every time you fly due to feedback from the spring tension on your joystick
If you flew the ARF and acquired short term muscle memory, then flew the Balsa Bandit using the same (pressure) inputs it would stall where the ARF did not.
EDIT: after writing this I realised you can set up a basic stall warning horn in a radio like the Taranis. With a bit of fine tuning it could be very accurate.
