Badger the midrange cruiser

I wanted some midrange cruiser and since I was pretty happy with Armattan Marmotte I've chosen Badger with 6" arms. There is enough room for DJI Airunit together with all other components and top plate can carry quite a big battery.

I had to wait a bit for all the parts due corona situation but the build went quite fine. I did a soldering mistake and connected powerleads. Fortunately I noticed that but spend quite some time fixing it. Cutting out Ummagrip to fit top plate cutouts was also fun (do not recommend). I've also printed RX antenna holder for the front as I want to test how this placement will work for me.

The maiden did not went that well. ESC or FC did some reset, quad fell down and FC died. I've send it back to FETtec and until they do their investigation I am using KISSv1. All works fine (GPS, DJI-MSP, etc.) but there is not enough UARTs so I am currently missing ESC telemetry.

The Bubblegum K2 props do not work that well for this build. Too much vibration going to FC causing all sorts of tunning issues. Not suer if more capacitance or different frame/motor would fix that but I've put Gemfan 6042x3 on and it's flying like a charm. Feels bit like plane compared to 5" Marmotte. Flight time looks promising. At least with Hero7 it feels much better than on 5".

Lost in Atlantic ocean. Rest in peace.

The build was very nice. I was pretty happy with it. 3.5mins on 1100mAh 5s freestyle. 6minutes on 1800mAh 5s crusing. With Hero7 in both cases.

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..
