I just received some presents from Quadrocopter. Here's what I"m using Cinestar 8 kit with 500 mm booms - I couldn't fit the copter in my car even with the props off if I used 550mm. Tiger U5 motors with Quadrocopter heavy lift motor plates MK 2.5 Flight control board MK Double Quadro 2XL power board Brushless gimbal custom made by Bill Collydas This board comes with 10 guage power wire already soldered through both boards. It just needs a EC5 One thing I see right off the bat is that the standard 12mm standoffs that comes with the CS8 can't be used to mount the board to the Cinestar center hub because the thread is not long enough to go through both boards. IF you look between the two boards above you'll see a black sleeve that the bolt has to go through. I'm thinking of getting 12mm standoffs with female threads on both ends and then using seperate fasteners that will screw in to the standoff. One for the hub side, one for the MK Power board side. Unless I can find a 12 mm standoff that has long threads on it. Let the fun begin.
