Brainfairy 3" - Slammed

This started in a toothpick frame that could handle a 20x20 board, and it was a crazy tight fit but it worked. But the 2mm bottom plate couldn't take crashes with the weight of the 1404s and the whole stack.

Pyro always comes through for me, and they did again. The 3" Toothfairy frame was everything I was looking for in this build. more room for the electronics, and enough space to keep the camera protected as well. I like that I have the choice to top or bottom mount the battery. I prefer top so I'm going to get some 15mm standoffs to slam the top plate 5mm, bringing the batt closer to the centerline.

Pids sliders are : Master X - 1.2, PD Bal - .08,  PD Gain - 1.2,  Stick Response- 1.5
Filter sliders are both at 1.7
Thinking about moving the sliders back up to 2 - motors fly ice cold and handles what little prop wash it gets better

AirbladeUAV has done it again and this time they've brought long range to the 5" class!

It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
