There are many reasons why one specific note can be tough. A above high C (on a Bb trumpet) has a fundemental frequency of around 1568 Hz. That corresponds to a wavelength of about 8.5 inches.
The problem could be due to a resonant node in the trumpet with that length (or rather half of that length). It can also be a resonant node in you - between the diaphragm and mouthpiece somewhere or any combination of the above. It doesn't really make much difference. It is in the way, and your embouchure will not solve it. You build strength up there and overpower the physics!
I seem to remember the Holton MF Horns had the valves further back than many other models, supposedly to get one of the nodes "out of the valve cluster".
One of my students got sick yesterday, so I spent the time working on my high range. The Monette valves are pretty far back too and I did not notice any breaks between G and double D.
Don't get the wrong impression - those notes just "come out", they are not useable yet!
