I just got my first set of Edge FBL 603mm blades in and I thought I'd physically compare them against my normal Radix 600 blades. Here is what I found:

Edge CG length = 315mm
Radix CG Length = 315mm

Edge CG cord = 16mm from leading edge
Radix CG cord = 16mm from leading edge

Edge cord = 55mm
Radix cord = 59mm

Edge total weight = 140g
Radix total weight = 136g

In summary - the Radix blades are 4 grams lighter, 4mm wider and 3mm shorter than the Edge but the CG's are almost identical. I'll get a chance to compare them in flight on my Logo600 this weekend. I'm curious to see if there is any noticeable difference in flight.

Man that's interesting stuff, I gotta start doing those exact measurements and all.

...Once upon a time there were Nitros, flybars and frequency pins...

interesting to know how your collective "pop" feels with the Edge. The set I tried for part of a flight felt mushy to me. I possibly could have improved that by changing some swash settings to add more pitch. I'm used to very stiff blades with lots of pop though. They did seem very stable and cyclics were decent.
