The Seagull

Update 4/22
For whom it may concern! Due to some delays in shipping (hardware), not all test units are out yet & the timeline for preorders is more likely to stretch into next month. The units that are out (including this one being flown) have answered a lot of my questions & informed some good changes to the base/arm layout - so I'm stoked to say at least that for the wait, we'll be shipping a much better product with all the right stuff in all the right places. Thanks!

This is a prototype.

For this top-mount cousin to the Raven, I wanted to check all the boxes that the low profile pod design doesn't deliver on. I first put pen to paper (literally) in November, and today I maidened the Seagull.

It's a wide-x frame on a lifted cage with a camera housing that's adjustable from 0° to 60° without putting props in view.

Notes:
Fits up to 5.5" propellers, currently.
Room for up to 3 separate stacks, several antenna mounting options & room to expand with things like rear-facing cameras, GPS modules, etc.
Narrow 5mm thick arms mount to a 2.5mm main plate from underneath with a 2mm brace & press fit nuts up top.
Stacks mount directly to the main plate without interference from the arms, for easier access to both.

I have a different part-list planned, but for now I've transplanted my 7" Raven right into it. Motors could be a bit higher Kv for 5" on 4s, but it flew great today with just a small bump to pitch P and D, putting them closer to stock BF. Some tuning left to do but footage was pretty smooth despite pretty high & gusty winds.

Dry Weight 345g, AUW with a CNHL 1300 & Session as shown is 640g

Excuse the dirty TPU haha, session case is well used & I touched the front pieces with carbon dust on my fingers. White TPU doesn't stay white for long :)

The last few pics are of an early prototype that's fully-printed. I made this only for testing part fitment - pics included to show standard Hero mount.

Back for an update. Progress?

Yo! Good timing, haha I just made an updated post a few days ago --> https://rotorbuilds.com/build/18365

Wow, that is such a smart design with the FPV camera angle and GoPro angle that adjust simultaneously! Really nice work man!

There have been some shipping delays with hardware on our test units unfortunately. I've made do using some off-sized standoffs, and another tester opted to supply his own HW so only two test units are out so far. Unfortunately it looks like pre-orders won't be up this month, but more likely in May.

Test units have answered some questions I had, and changes are being made to accomodate. The arms have to be split up so I can run the carbon weave straight down the arms. I've... bent an arm, which bent back okay.. but the other test unit also broke an arm a bit too easily so I'll most likely widen them just a tad as well. Either that, or have them cut thicker. I've also moved some hardware around and added more holes in the base plate for mounting & weight saving. Overall though, I've been progressively beating the crap out of this thing & the parts I was concerned about (the camera cage) are holding up really well.

Thanks for asking! Updating main post with this info.

very nice build

RZFPV   Mar 31, 2019  

im wondering if removing the tpu in the upper half and swapping it with another type of material would help save weight and give u the option t mkae wider/thicker arms.............

The Van   Mar 31, 2019 

Heard that! All of the TPU is undergoing some refinement, and that top piece isn't entirely necessary. There'll also be a few more cutouts for zipties and such in the main plate so that'll trim off a little.
It's likely that there'll be a 'standard' version with minimal TPU; and a 'special edition' of some sort that'll include some functional & aesthetic accessories. What you're looking at here is something in between. If anything I may make the arms a tad thicker, but they feel really solid at 5mm.

Thanks Fil! I've got just a few tweaks to make & the frame will be up for pre-order sometime in April. I'll throw an update up here & on social media for sure.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

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..
