Black Sparrow

After seeing a build here (but can't find it anymore) I decided to give it a try. I wanted something under 250g (with batteries) and I ended up exactly at 250!

This was a painful experience, very small parts and not much space to work with. I built it last winter but only been able to fly it recently. Very smooth ride, I like it very much!

Things I would change, I used XT60 connectors because that's what I had in my stuff, but I would replace them with XT30. The camera is simply beautiful but I might be tempted with the new combo camera/DVR.

Not shown in the picture, I've cut the spektrum binding plug and used Betaflight to bind.

Overall, very happy but this is the smaller I will build, I can't see as well as I use to and it was frustrating to solder some of these components!

Hah! I also rip a 3" Sparrow (stretched) on F20II's (I run 'em on he F20A T-Motor ESCs), but I too absolutely LOVE HGLRC stacks (especially the pin block connector ones like this, the F413 and the F440). Very nice build.

Thanks! I so love this build, for such a small thing it's really amazing and fun to fly!

Great looking frame/motor/prop combo! Your antenna tubes are probably at least twice as long as they can really be. I love the look, but in sporty maneuvers they will bend down into your props and get cut :(

Normtl Jun 22, 2019

Yes, they are long, I did cut them since I took the picture (removed about 1/3) they are actually really rigid and would probably break before bending. Anyway I wouldn’t like hitting a gate with these!

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
