I have up for sale one never used Rabbit Flight Controller. It comes with the daughter board with all of the goodies. I purchased this item in hopes of being able to use it on my custom copters but I am unable to do that. It is perfect for a Quad or Hex and maybe a Oct because these copters do not require servos. My mistake is your good luck. Asking $75.00 shipped anywhere in the US, other places maybe depending upon the shipping cost.
