nzer,
Did you fly the 200 per chance? I believe it had an actual restriction on reverse with the nosewhell off the ground. Are you suggesting it actually had an interlock to prevent deployment? (I've no idea, ive never sat in one). On the 3/4/500, however, there is, as I said, no actual restriction. Full reverse is available below 10'RA and allowed to be used once the mains are are on.
I SUPPOSE is you brought her in hot and held it off, you might get the sleaves out before the nose was down, but I'm in no hurry to try and prove that!!
