I have a older style jetovader on my Brekeley jet. I had is adjusted to about the middle of the movement to go up and down with the manual handle. Is see it has alot more down that I could adjust to (to keep the nose down during slow speed cruising). But if I do that, the up direction only gos to level, (no rooster tail  when up.) Is there a way to get everything out of the adjustment of the jetovader?
