This is a custom micro quad frame. It is the combination of the Zippin SpeederBike and the DreamCatcher. It flies like a bike and crashes like a dream. Here is some action footage: http://youtu.be/2tWLE1si2OsWe suggest to print this file with high-impact ABS filament: http://store.3dprintingsystems.com/1.75m_ABS_Filament_Crystal Om a UP! Plus 2 printer, it works great on 240?C with slow print speed and 0.15mm resolution. To complete the build, you need 8.5mm coreless motors with propellers, a brushed flight controller and a 500mah battery (ideally 20x45mm, like the Hubsan X4 packs). You can get suitable motors and flight controllers here: http://micro-motor-warehouse.com/collections/8mm-custom-builds
