VERY nice frame, craft and overall build. It just begs for a KK2. I bet it flew well with the NAZA.
Foam Addict did you see MikeysRC Foamboard quad? Cheap way to turn to the dark side but I would use 20A RCR SimonK Escs from MyRCMart.com and Hobbyking AXN Floater jet motors with 8X4.5 props and of course a KK2. Would make for a very agile acro copter.
