Seagull Micro

Hey folks! It's been a long while, but Nomad is still very much alive - so here's a quick update.

The Seagull has been available for some time now, but hasn't seen the same success as its Raven cousin. I think this is partly because of my lack of online presence - but more so because the design simply isn't as appealing. Indeed, it was made to be a bit of an 'anti-raven' and had a lot going for it - but suffice to say that V2 will be quite an overhaul. Meanwhile, I've been working on a contract design for a large-scale frame (AP & Industrial Use) as well as micro variants for both the Raven and Seagull lines. You've likely seen some of the micro Raven prototypes here already. Also, I teamed up with QSL to produce a 2207 motor that's available at quadstandardlabs.com (pics below) but I digress..

This prototype is a slammed 2.5" top-mount frame, housing a TinyHawk S stack and Runcam Racer 3, carried by Diatone's 1103 Mamba motors. The idea is to produce share-worthy DVR with no props in frame, with toothpick-like performance. This unit falls short for a few reasons:

The camera - The Racer Nano is.. put lightly.. terrible. What I first thought was a big smudge on the lens turned out to be caused by the camera's WDR function. It blurs light/dark transitions to a point where sometimes I just have no clue what I'm looking at. Big oof.

Prop size - This one took some time to realize, but the craft really should be 3". At 50g dry, it's a little too heavy for the powertrain to give you the right balance of flight time & performance. The next model will be sized for 3" props, and will likely use 13XX motors.

TPU - There are two TPU prints onboard. The camera cage, and the rear bit which is only there so it sits flat. The rear bit has to go as it's dead weight, and the camera cage needs to be more durable. Will be overhauling the cage with either a stronger print, or CF plates.

The good:
Believe it or not, the slammed layout and tighter distribution of weight makes a noticeable difference at these sizes. Coupled with good camera position, the feeling is super locked-in during flight.

Also, the motors are nice. And the variety of supported stack sizes (Whoop Boards, 16x16, and TinyHawk boards)

Any chance that you would share design files? I would love to try this one (looking for top mounted 2.5" frame)

Stylish, no props in view, and light. Very nice work!

Do you think you could fit an onboard diamond DVR into the stack? Maybe if you direct soldered the motor wires?

Definitely not with the Tinyhawk board, but maybe with a normal whoop-stack underneath! Also, this configuration has 10mm stack height where there will also be a 15mm variant 👍

What's the weight on this little guy?

Exactly 50.0g as pictured

i like the look of this compared to a traditional toothpick build. looking forward to finding out when i can get my paws on a 3" version.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
