I rec'd my new GY240 yesterday in the mail. Yay.
I installed the gyro with the GP C-12 Mini ESC per Heli-Max instructions.
Put Ultra Deans connectors between the new ESC and the battery feed. Instructions just say soldier in.
Followed spec and put an U.Deans on for the Rear Rotor connector.
I mounted the Gyro to the foam tape, but used 3M UltraLoc velcro-like strip to secure to inside rear lower chassis. This has proved very secure, and yet removable for adjustment, just use a small screwdriver to seperate. Set Gyro for about 60% Gain.
Once you plug in the battery, a few seconds later you'll hear the Gyro chirps. Arm the tail rotor just like it says to in the PDF and it'll do a four chirp, then a funky long beep pattern to confirm ready.
Tested, stable. Flies pretty good. Tail's pretty stable, but it sure takes some getting used to flying with a HH gyro. 
WARNING!!: They're not kidding when they say the tail will start up the second this Gyro detects about a 10 degree change in heading. Surprised the crap out of me for the first 5 times or so that I moved it myself with the main rotor parked. When you're learning to hover from scratch, this can be a problem, because every time you orient the heli on the ground for initial takeoff, if the Gyro's already locked on, it'll forever attempt to compensate to return to it's ZERO heading. 
So....
After I flew it for about 15 minutes, I benched it and installed a SPST microtoggle in the negative(-) battery path to the main ESC/3in1. I ziptied it to the top of the tailboom mount, facing back, up on, down off. While the toggle doesn't have a very high amperage rating, it will suffice for my needs while I am learning. I'll upgrade to a higher capacity toggle when this little bugger starts to show signs of stress. 
Now if I need to pick up the Axe and move it ANYWHERE i can just toggle down as I'm gripping the rear of the chassis and move it safely.

Word of caution. If you use Ultra Deans connectors for all your component connections (those tiny, combined male/female connectors), either MARK them, color them, buy the red and black ones, ANYTHING you can so that you don't accidentially cross connections anywhere. While I working on my heli, I didn't pay attention, and was distracted by my son (9yrs) and WHOOPS! plugged the LiPo into the wrong U.Deans connector. Remember folks, when the magic smoke escapes, it won't work anymore. One Rx board IC well done. MMMmmm.. Tasty. (reversed polarity cookage) 
One Axe CP Rx Board, 23$. One Sanford Indutrial Black Sharpie, 2.50$,
Telling your son to always pay attention, and then cooking your own toys, Priceless.
