You may find yourself in a catch-22, coz as you've been told, the main reason for the height restriction is 'buttock to knee' length - too long and you'll lose your knees when ejecting from a jet. Unfortunately, the RAF only recruits Fast Jet pilots and if you go to OASC saying you want to be a helo pilot they'll generally show you the door to the RN CIO or the Army CIO (for Army Air Corps)...
Again, the sound advice would be to go for it at OASC (and you DO want to be a FJ pilot don't you !) and if THEY tell you you're too tall (but would have been recruited otherwise) THEN suggest the multi-engine or rotary only options !?? You might be lucky !
