Hi, Received the I1 in January -- but have been too busy on other stuff to use it. I seem to remember getting some prop locks in the mail...but can't find them (ugh!)...and I just received the quick release props in teh mail with the one-time use warning. So my questions are: 1. Am I missing any other items? 2. Which is better - prop locks or quick release (I willl want to rebox my I1 after each outing). 3. I presume I have to upgrade my firmware on everything...can I go from stock to current or do I need any intermediate upgrades first? 4. Any significant capability upgrades or user warnings since January? Thanks! s.
