Each plane below set up in a vertical dive from 8000m to 0m (Set up in FMB as per Lexx's instructions prior thread-tks Lexx)
Measured at 1/4 speed (in game time compression)
Initial Velocity 200kph
Zero throttle.
No trim adjustment.
Using wonder woman view and therefore TAS measured velocity at which plane started to break up and altitude at which this happened.
velocity/altitude
Each dive repeated 3 times-mean figures quoted

P63C 1085/2271

LA73x20B 960/3527

Spit Ixc 1010/2587

Why the difference in alt for the 190D types? I repeated and got almost identical results.

The terminal velocity given is the point at which something fell off the plane - be it a wing or a rudder.

Lots of variables not accounted for but P47 seems quite fast in a dive and quite durable..

What version? 2.01 or 02?

Prop pitch for each? Yes, pitch makes a big difference. Try lowering pitch as speed goes above 400kph to at most 20% by 800kph. See if it doesn't help. Or even just lower pitch to 10-20% right from the start.

Wow! Thats alot of planes and testing there. Thanks. So the waypoint method works...Aussum News!!

Would be interesting to see timings associated with speeds and altitudes recorded. At 1/4 time speed it would be easier to do. But this could take a community effort.

btw, put a Tirpitz or something on the ground at the final waypoint and keep it in the gunsight. Better may be that big Gibralter Rock or something in the FMB Object list (its list number is below #20 I think).

Cheers -
prop pitch was auto, I was interested in the velocity at which the a/c broke up rather than acceleration, but noticed the jug was breaking up far further into dive/closer to ground so took note of altitude.
Lexx-the harbour walls at Sevastopol provided the aiming points (nice and long and bright-well visible from 8000m!)
Gib-version was 2.01, will re do for 2.02 after "official" release.
Will also try 45 degrees-though this look a lot more difficult to keep plane on course.
I like the idea of a community pull together-test with various trim+pitch, and perhaps pull out to level or plus 45 degree zoom at a set point/velocity.

And Lexx-halfway thrhough I thought I wish I'd recorded the times....Next time each will be recorded as a trk!
