Ethix CineRat 3" 6S DJI + GoPro

This is my first drone build. I ordered a GepRC Rocket Lite to start with after a learning the bare minimum in Liftoff. A friend shipped this frame to me from the States (I live in Shanghai, China) and due to Covid-related factory slowdowns it arrived not long after the Rocket Lite actually arrived. Because of this, I haven't had much actual flying time, so the flight footage is nothing remotely impressive.

With my wobbly, just-trying-to-stay-in-the-sky flying, I get about 7+ minutes without a GoPro and 5+ with the GoPro on a Tattu 6S 1050mAh 95C battery.

I have the TBS USB-C power cable to power the GoPro from a 5V output on the flight controller but didn't actually get it working yet. Haven't figured out why... So that should shave some weight from not needing the GoPro battery. Hopefully that can keep the flight time around 5 minutes as my flying progresses.

With the printed guards on, the propellers were scraping a bit against the guards. I did a couple flights to see if it would chip enough away from the guards, but the motors were getting hot. I'm waiting on some different props to try, but in the mean time I have taken the guards off and it flies great with lots of power. Again, I only have the GepRC Rocket Lite to compare it to.

Below is some flight footage from a GoPro run in my neighborhood. Turn on CC to see the DJI OSD info. I haven't changed any PIDs from default Betaflight 4.1 yet, but I did turn on Bidirectional D-Shot and the new dynamic filtering. I'm sure there are plenty of improvements that can be had by tuning the PIDs, but I'm just so new to flying that I wouldn't even know yet what is my fault and what can be tuned out. Regardless, I'm having so much fun...

Weights (without prop guards):

  • Base - 250g
  • With Battery - 422g
  • With Battery & GoPro - 561g (Includes GoPro battery, mounting screw, and ND Filter plus lens clip for GoPro 8)

I wish I would have read this before I bought the frame. I had the Cadxx Vista specifically in mind. Sounds like it's gonna be a challenge!!

Do you know what size hex the m2 hardware uses? just got mine and it's not a 1.5mm like i thought it would be.

Thanks for the info. I finally got mine finished. I just added washers to the bolts until i get my motor plates. i even ordered a second frame thinking it was just a mistake and the second frame didn't have them either so now tbs has sent me two sets. One retailer told me they come with the 3d print kit which makes zero sense. I ended up using my own hardware as well but need to order more 12mm bolts for when my motor plates arrive... who knows when that will be. coming from china.

Luckily I'm in China at the moment, so I'm sort of getting these things as the factories open up, but I'm still left feeling less and less enamored with this frame. It's... okay... but I still haven't found a set of props that work with the prop guards without smacking into them. It kinda defeats the purpose. It's nice that it has room to mount a 30x30 stack plus a Caddx Vista, sure. But with that I need a new antenna solution. Plus, there's not a truly reliable way to secure the camera angle with only one screw. Plus I can't even use the prop guards (due to prop size OR the lack of carbon plates for them. I've had screws go through them and don't have washers that work for me...). Plus the GoPro mount is so far back that the DJI antenna is covered by the battery (1050mAh 6S). Maybe it's better for non DJI folks, but it's too many consessions at this point.

i know what ya mean! i ended up toilet tanking my battery cause i couldnt fit a 1000mah 4s. been using the gemfan 3052 and only one rubs ever so slightly so i heated it up and stretched it so now it doesnt rub. and its annoying that they shipped these out without motor plates. i bet it would be a lot tougher to fit everything if i was using the dji stuff

Could the Vista fit in the front?
I'd like to use a 30x30 stack

revnelson   Apr 09, 2020 

Yes, it can. I think you would need to use a different antenna, or an extension piece, or get creative with where you mount the antenna if it's in front. I'm planning to build a 30x30 stack with the Vista into my spare frame kit. Hopefully I can get pictures up next week.

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..
