It was a little windy but we made it work. This is the Hobbyking MadCow 3D Flight Control Board (MC3DFCB).... I tested the 2D angle and horizon mode then onto the 3D horizon mode which handled better than I thought..... there will be a lot more of this type of flying later this weekend.... its fun hanging upside down.... just need to get more experienced with the sticks (obviously).
