This is one of the prototype Featherlight 5" builds by Falcon Multirotors out soon, I am building 2 identical, weight is 200.2g with everything but lipo. I have opted for the Stealth VTX which is heavier, but should provide much cleaner power over the VTX03.
I've also gone for a long XT60 pigtail to cable tie to the arm, this should stop it being yanked from the battery in a crash and ruining the power pads on the Ori 4in1 esc.
update: 22/09/2017: I've since moved to 25mm standoffs, so that I can run locknuts on the inner 20x20mm stack to further secure the arms. I've also switch the arm plates around so the one that holes the camera is now on the top, not the bottom. Due to the extra height of the standoffs, running these plates in reverse means they now fit perfectly again. I've increased weight slightly (maybe 0.5g) going for bigger standoffs, and switching out to nyloc nuts, but the endgame will be entirely worth it. It also means my stack has a little more height adding more room below for the battery strap, but also more room on top for the VTX.

Do you have the STL files for that FPV micro camera mount? Or know where I can buy it? I know the frame comes with carbon fiber camera mounts, but I really like that look.
Thanks!
Good tip, and was able to get a link from @Lazd! Here it is for references: https://www.thingiverse.com/thing:2759032
Thanks!
How much space did you leave between the frame and the Ori?
It looks like the battery strap is really tight in there.

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..

I'm not seeing an external capacitor like the ORI 25a ESC manufacturer claims is required. I'm trying to determine just how critical an external capacitor actually is so I'm wondering if you used a capacitor and if not have you had any issues because of it.
I did add one in the end yes - I soldered it to the top pads of the ESC, and then soldered motor wires to the bottom of the ESC pads - then you can heatshrink both together to stop the cap from being ripped off! :)
Did you have issues before you added the cap? I'll be using pretty small low current motors (RCX 1304 4000kv) with it so I was hoping to get away without one. I haven't needed a cap on any builds so far and I'm not entirely sold on them. They kind of seem like fairy dust to me because no matter what the issue is people tell you to stick a cap in it.
