First long range 7-inch build and first time making my own Li-Ion packs.
HDZero Freestyle VTX set to 1w
Using the Bardwell FC with an iFlight BLHeliS ESC flashed with BlueJay.
2806.5 motors are 1300kv
Ended up moving the GPS module on top of the GoPro Bones to improve reception. STL available here:
Weight varies wildly depending on batteries. No battery with GoPro is 585 grams. 6S2P 5600 total mAh brings it to 1300 grams.

Hey, I've also converted my Rekon 7 to the hdzero freestyle. How are you securing the vtx? I have a 3d print but not very thrilled with it.
Also had to move the GPS on top of the gopro, once adding hdzero I couldn't get sat lock so close to the vtx.

Just uploaded a side view of the VTX but I am just using 3mm plastic standoffs in the rear 30x30 bay. I installed the VTX upside down for easier access to MIPI cable and antenna. I think HDZero recommends 5mm gaps for cooling, but this works. Someone told me that the underside is where the hotter chipsets are, so installing it upside may be better for cooling as well.
Yeah, I am an HDZero fanboy, but the Freestyle sure puts out a lot of RF noise.

Hey thanks. I didn't think about mounting it upside down. I like the standoffs, I'll print some I think. Right now my 3d print is most likely blocking some air flow.
No issues with your antenna mounted on the arm like that? I'm always concerned that the props will make this move around just enough to get ripped up. Not really a fan of how HGLRC has the antenna on a swivel print, so going to change that. Sorry stealing a few of your ideas.
Did you ground the copper covering your gps wires? I did for mine though I think simply moving it away from the vtx did the trick as well.
Dig like the fuzzy print setting on that rear antenna mount :D

No issues so far with the antenna out there. The TBS antennas tend to be pretty stiff and some confidence with it being a diversity that, worse case, I'd still be able to fly.
I did ground the copper cover, but yeah, not sure if it is needed. Like you said, main issue is the VTX.
Steal away! I did. :)

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..
