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.
My Armattan Stunt quad uses 2600KV motors on 3S with 8X4.5 props. Stunt quads and micro quads do better with High KV motors. Aerial Video and FPV with lower KV for less vibration and better stability.
