Default RE: looking for a phoenix 8

Maybe the 170 mph was actually 170 kph... easy for the gun to just have been in metric mode.

What about reducing the airfoil thickness in the P7/P8 rather than going to an F1 design. Going with a P8 might actually make this easier to accomplish since the cores could be cut fresh. On the other hand a P7 fuse/tail kit could be bought and a new wing made. I would want a foam core wing if aiming to hit 200 mph - that's some serious speed. Full carbon veil treatment and heck, maybe even some square CF spars lining the sides of the retract wells. Full covers and paint of course.

What kind of C rating discharge are we talking about? I know there's a guy who setup a GP revolver (I believe) with 10s. It weighed a ton (10-11 lbs I think) but it moved out in a serious way. Unlimited vertical was an understatement - it just vanished. That guy had really good eyes (or perhaps the eye in hid mind).

I just did a quick back-of-the envelope calculation:

Thrust = Drag

Drag = 1/2(rho)V**2SCd - Fortran notation used to denote velocity squared

Cool,

its been a while since I read anyone making an equation post using Fortran notation. I might have used v^2 notation. Actually this notation is something that applications such as Firefox understand. Ever try punching in 10^2 in the FF Google field? All kind of conversions can be done.
