Hi All, here is my 250 FPV Racer I designed and 3D printed. It uses a mini APM as the flight controller and also has a GPS and telemetry for missions. The arms are 15mm carbon tubes with SN20A esc's in the arms. The files can be downloaded here http://www.thingiverse.com/thing:1256900

Telemetry/OSD board at the top, Mini APM in the middle and PDB at the bottom. 

688g AUW with 4S 2200mah battery

483g with GoPro and no battery. 

367g without battery and GoPro

Hi all, I designed a mount for the RFD900+ which goes in a JR module bay so that I can have long range telemetry with a bluetooth bridge for my smartphone / computer. The module uses the transmitter's battery as a power source. Also, you need to enable the external receiver for the Taranis to power the module.
