This is meant to replace my 6" long range quad which I have recently lost. https://rotorbuilds.com/build/13379

This was made from a previous experimentall quad: https://rotorbuilds.com/build/17099

First test flight was 14min at an avg speed of over 50kmh with a 4s VTC6 LiIon pack until 2.9V per celll (2600mAh used).

The upsidedown front motors help in 2 ways: 1. the larger props don't get in gopro's FOV even on a lower angle. 2. 6" props can be used on the front side even though this frame only supports 5.5" props simple because the props no longer hit the front spacers. The back side require a small modification though for 6" to be used. This can be transformed into an extremly light and compact 6" setup with insane flight times.

Next step is to make it 50g lighter by giving up some hero8 parts (battery, battery door, bottom adapters) and by replacing the hero8 mount with a lighter one.
I will also build a 4s Molicel 21700 pack to increase flight time to 18min or more. Also I might give it a try with 6" foldable props.

Here I used it with 5.5" props to shoot an MX race.

Went to 3-4km with it but it can do more. I am also flying it with 6s Lion when I need more flight time.

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..

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..
