Maybe I’m misreading Apen’s original post. He seems scared he might stall a non spin certified airplane and end up in a spin unintentionally. I stand by my comments regarding a lack of understanding of the aerodynamics associated with a spin entry. You would need to make deliberate control inputs to enter a spin. Don’t make those control inputs and you won’t spin, if you happen to apply the inputs required to enter a spin, know the inputs required to prevent the spin developing.
The concern around stalling / spinning displayed by the majority of pilots is the direct result of poor instruction. I’ve flown with many instructors over the years who are terrified of stalling, let alone spinning. A couple of flying schools who trained instructors sent their instructor candidates to me for the “advanced stalling” sequences because the instructor trainers wouldn’t deliver the training.
