QAV 400 Dragonlink Receiver Bracket

thingiverse

This mounting bracket for a QAV400 has two sets of four holes on its bottom plate, possibly intended for landing gear but currently unused. Four M4 nuts and screws are required for assembly; the nut holes are slightly undersized so that nuts can be melted in place for permanent locking using a soldering iron. The purpose of this modification was to relocate the UHF transmitter away from other RF sources, which improved noise levels as detected by a spectrum analyzer. Attached is the SKP file for customization. Additionally, a 300ma 5v step-down regulator from Pololu has been soldered onto the power distribution board and wired directly to the bracket for separate receiver powering. Many users have experienced dropouts and motor cutoffs; thus, it is advised to power the UHF receiver separately from the CC3D or, if that's not possible, use a 5v source with jumper cables connecting to the CC3D's power pins rather than the reverse.
