grOOvy
I'm a short-ar$e, 5' 5''. Had my medical cat deferred at OASC due to being too short (at 16) for pilot (old 30 hr Flying Scholarship actually). Went back a couple of years later having grown not one millimetre and magically met all the measurement requirements; my functional reach was recorded as exactly 720mm.
Just go for it, you have nothing to lose.
