Uh, according to my old Omega the 0.44 C.205 (havent tried with 0.441 yet) takes 6'20" to get to 20,000ft (about 6,100mt).
100% fuel, no WEP, 2x20mm, 2x12,7mm, default best climb speed. Her climb rates to 20K range from 3,250 to 2,800ft/min. Average climb rate to 20K is about 3,100ft/min.
We know the real kite took about 7'15" to get to 7,000mt. I tried time to 22,960ft and she takes 7'28" to get there. So far it is enuff for me ....

After all we beta testers are not too demanding and whiners ...
