I was looking to build a light and agile acro practice quad that wasn't loud, that could take a load of impacts and survive!

Having seen Mr Shutterbug and Kabab's videos I was really interested in building a 3" toothpick but using a Caddx Vista so I can make the most of my DJI Goggles. :) So the shopping list developed...

Best intro to 3 inch toothpicks from KabaFPV

The Caddx Vista de-casing brings obvious disadvantages (fan required to update the Vista with the DJI Assitant due to overheating and no warranty) but brings a good weight saving (~10g) and all the useful packaging benefits.

I worked on a canopy and spacer combination in Fusion 360 to keep things as low profile as possible, which I've popped on thingiverse.com.

This is by far the most fun quad I own now to fly!

Indestructible, long flight times, agile, small kit bag contents, not silly expensive and QUIET!!

I've not really explained the build process, but took a lot of photos to describe it all. Comment if you want any steers!

Maiden flight and first play...

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..

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..
