Description
The Cyrus frame has been designed immediately after Runcam Split was released.
After its launch it became obvious that its use on traditional frames will mean few problems: props in view, frame in view and/or camera would be exposed to crashes thus ruining the investment.
I wasn’t happy with any of the frames that ware on the market so together with a friend designer - BRDM (https://armattanproductions.com/pages/designer_product_grid/1218), we got to work.
Our co-operation gave birth to the Cyrus.
We set of with a few clear requirements for the new frame:
- to allow for unobstructed field of view for the wide angle HD recording;
- to fit Runcam Swift without any mods required;
- to protect the camera unit as much as possible;
- to allow for wide range of uptilt angles as well as GoPro lens use;
- to keep the centre of gravity of the frame as close to the flight controller as possible;
- to be a true X racing frame;
- to have replaceable arms, but maintain maximum frame rigidity;
- to allow for easy maintenance of the stack.
We have managed to tick off all of the above points and the frame went through two prototype iterations before we have decided to release it.
The frame allows for a bottom mounted battery, 4in1 esc, FC/PDB and Split in one single stack. It also allows for part of the stack to be mounted from the top plate. This way it’s possible to have the main quad stack connected permanently to the bottom part of the quad as the Split and VTX is part of the top of the frame.
The arms are deliberately made thin. This is both to save some weight as well as to take the first punishment of a crash and save the rest of the frame should it come to worst. For this reason there are 5 arms included in the kit! You may not be able to easily mount ESC’s on them, for this reason I suggest using a 4in1. There is ample space in the stack for it.
The frame comes together really well, but as the vertical plates are only 22mm apart it can get a bit tight in that space. For this reason I suggest planning your wire routing carefully before finalising the assembly.
The camera mounts allow for both the standard lens as well as the gopro lens. The uptilt can be anything between 5 and 90 degrees (in some cases some standoffs would need to be removed), so any kind of pilot should be able to use it.
I would like to mention that I adopted some of ideas from other frames, like DemonRC and BRDM - props to those guys!
Additional Information
Recomended components for this frame:
1. Runcam Split :)
2. 4 in 1 ESC (i'm using Spedix 30A)
3. FC with built in PDB (I'm using Matek F405-OSD)
4. small receiver (I'm using Frsky XSR)
5. small VTX with a pigtail (TBS Unify V2)
6. depending on all the other components used it might be advisable to use a separate BEC to feed the Split with clear and stable 5V current (Diatone Mini 2A BEC).
7. frame can handle any motor with 16x16 and 16x19 mounting holes (BrotherHobby Returner V5 Deadpool)

I bought this frame because like everyone else, i got the run cam split and i didn't like the props in view. this is only the second build i have done, but i like this frame very much. It was Fairly easy to put together (even without instructions). Its well balanced, and fun to fly. I have had a few hard crashes and i have not broken any part of the frame and the camera was well protected. The only down side to this is with the VTX i am using, the antenna, and VTX fitting are sticking out of the top a little bit. I clipped the top on a tree and it ripped the VTX cables off and i lost video, the resulting crash then ripped my VTX antenna off. I have since mounted the VTX so the antenna is coming out of the bottom, but if i need to buy another i will be looking at different designs. I would recommennd using a vtx in the same design as the build pictured on the main page for this frame. the frame is easy to take apart to gain access to the internal stack, just 4 screws and your in!! At only $60 this frame is well worth it, if only it came with the Armattan lifetime warranty *wink wink* i cant think of anything else to say about this frame. thank you to the creators for taking the time to figure this frame out, its everything you designed it to be and i think it looks great!!!
