I hope there are some heli instructors out there that can help me on this one.
When demo-ing vortex ring, I find that it is quite hard to get the robbie (22) into this state.
Here's what I do:
I reduce power to about 13-14 inch MAP,
Reduce speed to about 20 kts and a ROD of about 500-800 feet/min.
But I just can't get the symptoms to show CLEARLY. Is it just that the robbie is designed this way or am I doing something wrong.
Advice and Input, Please.
