I got my ESKY radio talking to the Crazyflie today. Here are a few observations.
First, as mentioned on the bitcraze blog, you need to flip the switches under the batteries. The radio default is 1: off, 2:on. I reversed them to 1: on, 2: off and it started making more sense although some of the channel directions are backwards so I started playing with the channel reverse switches on the front of the radio. Here are the settings that worked for me:
AIL = Normal
ELE = Reverse
THR = Normal
RUD = Reverse
At this point, I could control the crazyflie and it actually works pretty well although the controls seemed a bit sluggish - especially after getting used to the overly twitchy PS3 controller. With ESKY it felt like it didn't have much power. I know this little guy can be very zippy after playing with the PS3 controller so much. Also, the crazyflie is in + mode which tends to confuse me since I always fly my quads in X mode. I was able to tweak the firmware a bit and now it is much more responsive and flying in X mode.
Here's the tweaks to the code:

This seems to be working perfectly although I might tweak the settings a bit more for even more responsiveness (maybe this is just PS3 controller withdrawal). Also, one other observations is the start-up order. It seems to work the best to turn on the crazyflie, wait for the green light to flash, then turn on the radio and wait for the green light to come on solid. Also, be sure to turn the throttle down on the radio before turning it on... doh!
I must say that I'm lovin' my crazyflie!
