FlexRC Mini Owl - Extreme FPV Proximity Racing Drone - DIY Build Instructions 

 

 

This guide will walk you through the detailed build steps using the 

FlexRC Mini Owl Extreme 

FPV Racing Drone DIY Kit

.  The kit contains everything you need to build your Mini Owl except 

the radio receiver, which is purchased as an add-on to the kit.  In our example, we’ll be using 
the Lemon Rx DSMX Satellite Receiver. The instructions also include the installation of an 
optional Pololu voltage regulator. 
 
The Mini Owl can be built as a pusher (motors “upside down”) or a standard (motors right side 
up) quadcopter.  We’re building ours as a standard quadcopter.  There is very little difference in 
the two builds other than motor directions and prop mounting.
