Armattan Rooster 6" Crossfire w/ Runcam Split

Here it is.... the Armattan Rooster 6" with a Runcam Split and Crossfire system. I am kind of glad I waited a little before start building because there are a lot more 3D printed parts available as time goes on.  I also included a list of 3D printed parts, so if you are interested in printing your own parts you can find the 3d files below.

The first thing I did is soft mount the Betaflight F4 flight controller with rubber dampers. This frame only allows room for a stack that is 2 high, so I cannot use a 4 in 1 esc with a RunCam Split. The next thing I need is a way to mount the RunCam Split camera because it is smaller than a standard FPV camera. Thingiverse is my go to site for all the 3D printed source and that is where I found camera mount. Just to be clear, everything I printed for the Rooster is with TPU.

After building the Armattan Chameleon I did not like how I ran the power plug in the back of the quad. So, this time around I will try running it in the front, right behind the GoPro mount.

Here are a few more 3D printed parts that I though worked well with my setup:

  • TBS Unify VTX mount (non HV version, it is smaller)
  • Front cage skid (help protect the shiny Ti cage)
  • Crossfire Micro Rx Mount (I did not use the original Armattan Rooster Frame Standard VTX Plate. I did have to modify the 3D file a little because I did not need the T part on top)
  • Crossfire Immortal Antenna (even with TPU is was firm enough to keep it in place)
  • XT60 Battery Strap (Keeps the power cable in place)

A few thoughts about this build. The hardware that is included with the $100 frame is a bit disappointing. When I first received the Rooster from Heli Nation I was like, Cool it comes with upgraded screws. As I start building I did not have any problems with the screw, it was the Skunk Nuts. The M3 Sunk Nuts are defective because there is not enough thread inside. So, when I apply some torque to tighten the screws it will slip. I am not able to secure the arms and now the arms are loose. I have owned many Armattan frames and this is the first time I have ever experience such low quality hardware. At first I thought I stripped the screws. So I tried using my own m3 screw and I still had the same issue. I also thought it was just one defective M3 Sunk Nuts but the majority of them are like that. I happen to have my own Skunk Nuts because I us them with the DSLR brushless gimbals I use to build.

Other than that, the build seems to come together as it should. I opt for a 6 inch frame because I already have a 5 inch Chameleon so whats the point in having 2 frames that are so similar. Plus I can use 5 inch props on a 6 inch frame too.

awesome ! have you considered FC like Lumenier Alpha AIO ? that would allow you to skip escs from the arms ... that would make 2 boards stack, and there should be enough space to place a vtx and Rx ...

wrong17   Jul 17, 2018 

I never looked in to the 4in1 with a built in FC and I do not think the Lumenier Alpha AIO will work well on the rooster. Take a look at where the USB plug is positioned. It will be difficult to access it on a Rooster frame. I can turn the board 90 degrees and remap the motors but I am not sure if the part where you solder the power wires is sticking out too far. The VTX and RX is not really a space issue because I have plenty of room to put it behine the 30.5x30.5 stack.

eMarcel   Jul 18, 2018 

You are right, Lumenier Alpha AIO has tricky layout. As a mater of fact we don't use USB port too often. I think I will give it a try... I have some broken boards I will test on this frame ,once I've got it. If that works we could have some pretty clean build with no escs on arms, only two boards stack and the SPLIT on board. VTX and RX will always fit somewhere if can't be placed on top of the stack. I'll keep you posted with the results. Soon I will publish on rototbuilds my 3" build on Nano 130mm frame using mentioned approach :)

Here is the build I mentioned: https://rotorbuilds.com/build/13881

how about props in a view ?

This Rooster build is my first iteration. Since then I removed the split and mounted a GoPro Session 5 instead.But you are right about the props being in view of the camera. Take a look at the picture I attached. You can see the props on the lower bottom corners.

eMarcel   Jul 18, 2018 

Actually it is not that bad! Could be even better to put 5" props on that 6" frame ...

Where did you find that hook velcro for the battery?

wrong17   Mar 05, 2018 

I got them at the local hardware store (home depot). It is called, Scotch 1 in. x 10 ft. Black Extreme Fasteners.

Beautiful build! I'm planning on using the original split, but was worried about not being able to provide proper current for it, since it's quite hungry. Have you had any issues with using your FC / Split combo?

wrong17   Mar 01, 2018 

I am using the original Runcam split and the Betaflight f4 (1.5a BEC) seem to do fine powering up the Split and TBS Unify Pro 5G8 V2.

dsalni   Mar 02, 2018 

Awesome. My Betaflight F4 will be here Monday, can't wait to try it all out!

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

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..
