A budget 3" build built around some DYS motors I got from NewBeeDrone during the closing out sale. The batteries awere also purchased on sale for $11 a pop, not the $25 listed below.

This build does not use a PDB as the omnibus F3 can take battery voltage, however, a micro BEC was added to power the cam and VTx since the F3 board cannot supply enough current through the 5V reg to power the Rx, Tx, and cam.
