3inch HD freestyle fun < 250g

I wanted to try to build a freestyle frame that stayed below the 250g limit, yet is as much fun as possible. When looking at the available frames, i couldn't find what i was looking for - a frame looking similar to an 3" version of the popular Marmotte-frame. Prepared for a 20x20mm dual stack build, as low in height as possible. So i designed one myself, which you can see in this build. I either will upload the files to Thingiverse, or make this frame available for purchase.

It is flying really amazing, especially now with Emuflight. Highly suggested for all frames 5" and below.
In the pictures you can see the buzzer. This was removed in the latest version, i'll update some nicer pics later on, as well as videos as they come.

The 3D-printed parts holding the camera look very useful. Please post the STLs for these on Thingiverse if you are happy to share!

Hi Stephen! Sure, i'll try to upload them there. It's just that I've made many changes since then, also added an Immortal T mount to it. I've also changed the motors to more powerful onces so i can carry a GoPro Session as well. Will post this as a different build though (and above 250g of course with the session).

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. 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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
