What I do...( I'm no Ace either, but it works)....is I have the elevator trim up and down mapped to a hat switch...push it forward, and it trims nose down for high speed escapes, pull it back and it trims nose up....just the ticket for beating the compression-in-a-dive thing.
Dunno if you have any hat switches spare, but it makes trim a matter of moving your thumb a fraction of an inch, instead of fumbling for the K and I keys.
PS, I find that where the 109 really excells is in a vertical rolling scissors, it cant outrun mopst things, cant out turn 'em in a flat circle fight, but it can spiral climb like no other plane can.
if they follow, they stall earlier than you do....if they're smart enough not to follow, you have forced them to break.
Works for me anyway.
