The Bell206 vs H500 are a good example for you. (Hydraulics being required for the bigger chord).
Ok, why can I fly a B205 hydraulics off, but not a Bell 412?
As for the insults, they are more an "old timers" joke...... We have not had this much fun since THE Lu Zukerman (of the famous Lu Zuckerman Effect) unfortunately departed this earth so that he could explain cloud dynamics, universal mechanical laws and what is wrong with corriolis and the R22 to the big Senior Pilot in the sky. Who I am convinced would have enjoyed the experience.
Luckily, we have the Zuckerman Effect as a legacy of his particular genius, and our focus on this thread is more nostalgic than anything else. Don't take it personally.
