I bought the ARF version and found problems with the new Hobbyking Quanum outlaw180 frame. the front blades contact the camera mount bolts as they sweep by underneath the top deck, causing broken blades when under full power. I went through 4 sets of gemfan bullnose blades (5x4.5) before I could figure out what was happening. at first I thought it was hitting my battery lead, but I noticed on the third try it was hitting the nut on the bottom of the top camera mount bolts. I sanded down the frame to allow the blades to clear the area where it was rubbing and snapping and it flew fine the rest of the day. MAJOR DEFECT IN DESIGN or badly assembled ARF.
