Hello Jellyson,

Thank you for your thoughts on heli stability. You obviously know a lot more about the subject than me. But I honestly don'y feel taht dynamically unstable inevitably means out-of-bounds for human beings. I like the picture of balancing a tennis ball on top of a football - difficult but not impossible. Dynamically unstable refers to the fact that any given equilibrium will only be temporary - this corresponds very precisely with my experience with RC helicopters so far. It is difficult to hit the equilibrium in the first place - and it will not maintain itself.

Best regards,
