My own version of Tadpole 3 using a 20x20 Brainfpv Radix LI. i didn't like the 20x20 fc mount included in the tadpole frame so I just replaced the FC mount using my old R249 Diatone Plastic FC cover as a base, then double sided it on the bottom plate.

How do you like it on 4s? I have a similar build and its great on 3s.

usually i just use the default PIDs and settings on the radix on all of my built. I'm pretty satisfied with it. for this build i only noticed of the prop wash during a big split-s recovery which is mostly pilot error.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
