Ok - but can somebody show me the feathering shaft in the exploded view? You can download it here - [link]http://www.walkera.com/en1/fileDown.jsp?file=%2Fcn%2Fupload%2Fpicture%2FZ2004 2604_ex.jpg&la=en[/link]

Loose grips won't change the pitch (create sloppy pitch) unless you have them real real loose. The suggested setup for the falcon varies depending on the source but basically they need to be loose enough to straighten themselves out as the head spins. This link gives some pretty good instructions for adjusting the blade grips at the bottom, as well as a few methods to balance the blades. [link]http://www.rc-airplane-world.com/rotor-blade-balancing.html[/link] but it sounds like you have them about right. And the "self correcting" he's referring to means once the head is spinning the blades will "self correct" so they are 90° to the flybar or in line with the grips.

I prefer this method of balancing - this does static and dynamic in a couple of real easy steps. I got a digital scale from harborfreight.com for 10 bucks. And use trim tape - trying to sand the bottom of these hard undercambered plastic blades would take forever and possibly affect flight characteristics.

"tip speed" of the falcon blades changes constantly - since the pitch is fixed the only thing that the throttle changes is the head speed. But I will agree that you don't want to get wacked by one of these blades, and common sense says to practice safety on all rc helis, not just the "big ones". If you develop bad habits with the falcon, or even a small coaxial, they will carry over to when you get that trex 600.

There is a dedicated thread to the falcon here - [link]http://www.rcuniverse.com/forum/m_4826535/tm.htm[/link] And just about every problem/malfuntion the falcon/walkera4/honeybee fp is capable of has been discussed there. There are also lots of mods that make it more reliable.
