Problem only with those two planes?
Everything else works?

Only with those two planes, all the others are ok

Go ask Ultrapack why they didn't include the awesome cockpits for the planes, HSFX 4.1 has the cockpits for the birds, and SAS has a HSFX/UP compatible addon cockpit for the Sabre by Freddy, screenshots of it on AAA somewhere.

If you installed another mod, like Korea Pack, then it may be conflicting.
If not, then reinstall is only thing I can suggest...I don't know.

...HSFX 4.1 has the cockpits for the birds...

Freddy's cockpits? No, it doesn't. HSFX and UP use same cockpits for Sabre and Panther...the YP-80 cockpit.

It might also be a corrupt install.

For example ... I don't have a Graff Zeplin in my UP2.0 but everything else works ... go figure.
