Stall characteristics and alpha depend on chord's length and wing's aspect, except for the usual design mitigations.
The longer the chord and lower the aspect, the higher the alpha as a general rule.
To supplement your opening post:
Inst. turn - wing loading (mainly)
Sust. turn - wing loading, wing's aspect ratio and net thrust
Hope this helps
