3D model description

This is outdoor FPV multirotor flight platform (180mm racing drone chassis), rigid and compact design in its category : XL-RCM 28.0 XPANDER. The design was inspired by previous by my previous foldable quadcopter size frame which is the "XL-RCM 8.0 XYPHER" with slightly bigger airframe to accommodate 180 size multirotor parts and 1806 type motors. Design aim to make a portable size racer that can be easily transported inside small tupperware plastic, small boxes and inside a pouch or medium size pockets. Highly innovative in design and looks aerodynamic too. Project started late 2015 and completed by February 2016 but the electronics installation was never completed due to insufficient budget and lack of time to put attention to it since i have other important hobbies i need to work on. The XPANDER frame was donated to other FPV builder which turned into a drone racer by mid 2016.

On the XPANDER chassis: All rotor are are fully foldable with front pair of rotor arm have higher off-set motor mount to allow more compact folding size. Front of the frame have special 1/4 size lens mounting to hold the FPV CMOS camera module. The mid frame include cavity to fit almost any of today electronics boards for multirotors such as small receiver, flight controllers (CC3D, SP RACING, NAZE32 and etc) and also extra space to cram small mini 5.8ghz video transmitter (25~600mw). Rotor arm have placeholder for 180~200 racer size ESC (Simonk/BLheli) and motor mounting screw size that fit any 1806 motor type from 180mm size racer category. Each rotor arm is held by M4 type long screw shaft and bolts. Battery are to be mounted below the belly by DIY straps or means there no proper battery bay since most drone racer size battery are in various shape an sizes which ideally best to mount via improvised DIY straps or velcro.
