Armattan Beaver HDZero Freestyle

Always been a fan of Armattan frames. They are well thought out and made, and with this new version there are so many ways to mount and configure your components.

I went with mounting my flight controller stack up front, and the HDzero Freestyle VTX in the back. The frame comes with a few options for where to put standoffs. For this layout I've put the standoff in the center and removed the press nuts on the bottom plate. The front press nuts on the top plate are kept in and used to hold the GoPro mount.

For motors I've gone with 2207.5, 1969kv (bit of an odd size, but well made and tested). This build really screams and it's easy to do maintenance. Links to parts and 3d prints below. A few of the prints I either designed and made myself or modified files from others. The GoPro mount is a remix of a few existing models, however I don't like adjustable prints so this one is solid and locked to specific angles.

will the hdzero freestyle V2 fit this frame? New pilot/builder here..
i have my hdzero goggles and freestyle vtx V2 on route. wanting to build this quad

Yes and much easier. I believe that uses a 20x20 mounting pattern, the frame already has these holes drilled.

I am building my first fpv drone with the speedy bee f7 v3 and the HDZero Freestyle. I am starting to do research on how to power the VTX. Were you able to power the freestyle through the plug-in's. (no soldering) It's looking like i'd just have to solder the battery, motors, and 4 RX pads in my build.

Thank you for the reply! I currently got everything wired and now i'm flashing everything like the radio/ TX, FC, and now i'm on the ECS. I'm being very cautious since it's my first build. But your pictures helped me a ton getting setup! It gave me confidence that it was okay to plug an R1 into a T1 haha. Sadly the drone frame i picked is longer than the HD-Zero cable so i'm waiting on a longer one

Glad my build helped someone! Your FC stack would have come with a cable as well. Instead of waiting, just splice the wires and make your own. No harm in doing this, easy bit to solder and good to learn anyway.

Only harm you could possibly do with swapped wires is + and -. Swapped RX and TX doesn't do any harm, it'll just result in an incorrect configuration so your OSD wouldn't work.

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..
