carrellh,

WOW! Thank you--that's the explanation that makes me understand what's happening up there when I open the throttle. I won't take your numbers literally, but it's a good comparison.

I realize the Harrier 3-D is not made for eye watering speed so I'm going to start off big prop/low pitch.

Since all planes handle differently I'm going to ask around and see who's been flying Harriers and what they use.

Thanks again, EXPO
