This might be rework off my older Martian or complete new build, I do not remember. I just discovered it is not listed in my builds.
This one has 3mm bottom plate and 2mm top plate that makes it tank. All the edges are manually chamfered. I also designed and 3d printed the antenna holder in the back.

It is rather heavy though. With 5.5" props the weight is not a big problem and paired with 5s battery it is a blast. Pictures are with 6" Kingkong bi-blades that I would like to test.

I had trouble tunning out some mid-throttle oscilations so I added 330uF 35V cap on each ESC and one 1000uF 35V cap on power leads. That seems to solve the issue.

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..
