Tough build! Saw a few peeps building this super light setup and thought I’d try! Fitting everything in was fun but challenging. Getting some runcam TX200 coming in the mail soon so I’ll have that replace the vtx03. And some dal T5051c to compliment the lightness.

It currently sits at 207.3g as it is. I, of course, will reweigh it after replacing the vtx and cleaning up some of the wires.

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 one and if not have you had any issues because of it.

To be honest, I believe i omitted the use of a capacitor and it seemed to have worked fine. It has been awhile since I've touched this one (I need to replace the ESC due to a crash).

Hey might you have a build video for this ? Im doing my first build with this frame this summer and could use any help i can get. Thanks!!
Yours looks fantastic!

Hey! Sorry it has been awhile since I've logged in, but I unfortunately don't. But if it is your first build it will be a tough one! There will be plenty of tutorials online on how to build a quad and this one is just a tight fit! All this is presuming you have yet to build your quad.

you might want to protect the RX antenna better. Your monopoles are exposed. Other than that, this build looks awesome!

Do bigger boards fit on this frame? i.e 36x36 standard sized flight controllers and 4-in-1 escs?

Also, is the runcam tx200 better than the eachine vtx03? Thanks!

Regular-sized FCs can fit, however, you will be building along the standoffs supporting the frame. With some modifications and your own standoffs to fit, and possibly some 3D printing, you could get a stack working and still have a camera mount. Unfortunately they only include 2 sizes of vertical carbon fiber for the cam mount (I don’t have the measurement available).
So far, the Runcam tx200 was used to mount behind the camera since it was my best bet at fitting everything in this build. So Far I’m liking the TX200 but the VTX03 have been my favorite light video transmitters until now.

Thanks for your reply, so are you saying with a regular sized fc I'm not going to be able to use the provided fpv camera mounts?

TheLeprechaunPirate   Jan 29, 2018 

You could, you’ll just have to find the right spacer standoffs to go both above and below the flight controller to make it level.

what's the thingiverse file for that cam protector?

TheLeprechaunPirate   Jan 18, 2018 

It has been awhile since I've pulled that file from the site. I'll try to find it, and if i do I'll get back to you.

What'd the weight come out to be? I've been looking at a Featherlight for awhile, so nice to see a current build.

just saw the note lol I'll check back soon

207.3g right now as it is! Hoping to shave off another 2-3g day or so but getting rid of unnecessary cables and such.

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..
