Hey guys, what would be the difference in flight characteristics between the "compressed X" (arms further up) and "true x" (how I have them now further back)?

I am now thinking of going compressed X but purely for build reasons. Namely, the rear motor wires really need to go a long ways for a true x. I had opted for true X also purely for build reasons - so those countersunk nuts wouldn't be directly under the rear stack.

I do notice that my other micro LRs are more of a "compressed X" if wheelbase is anything to go by.

what is a compressed-x frame?

It's like a regular X but it's smooshed, bruh.

Just got the carbon fiber cut of this adapter done by CNC Madness.  It is sick.    





I posted the design on Thingiverse but if you want CNC Madness to cut you one, he has the exact same STL file:

Hi Ronin,

This build is really coming a long nicely. I am looking forward to seeing the finished product.

That FC mount is trick,  GOOD JOB  

Thanks man.  Designing mounts for this thing has been an epic pain lol.    

Take this, Armattan lol.

Amazing man, this reminds me... I need to start designing my canopy!!

Fitment ... check!  It always looks so roomy without the wiring lol. For the most part, I am mimicking the Roma build.



I opted to use one of the stack standoffs itself as a mount for a vertical Immortal T.  I'd be worried if this stack had the FC but it's just the RX and VTX.



I had to get creative with the whoop adapter mounting lol.  



This may look like a lot of space for just a tiny Crossfire RX but just watch it will be pretty cramped with all the wiring harnesses.



The GPS mount for this frame was an *epic* pain in the ass to design lol. 





I'm fairly comfortable with the stack spacing ...



I designed two styles of skids.  I think I'll opt for the original design without the spike.  And, yes, those holes are offset lol.  Airblade UAV got super sneaky with their motors and made them 9x12.  I really wish they didn't do that.



Now its onto motor harness management.  Yay. 

I love watching your creations come together!

Nice skids and GPS mount design.  Love the colour choice. This will be the sharpest looking Bobcat going around.  

That might be because it is the only Bobcat around LOL. I ordered direct from Armattan so the retailers just got them in stock.

To be honest, so far I would not recommend this frame. I personally do not regret getting it but I have really weird requirements which are a proper alu camera cage and die cut lipo pad lol. To me, a frame that nails those two things are a likely buy. Totally stupid I know but that's ok. So for "normal" people I believe this frame is way, way, way too heavy for wanting to be 4 inch LR. I am very curious to see how this works out.

the bobcat is declarated as cinematic platform, my understanding is its not made for lr, its made to be used as a non-propguarded cinewhoop :-) it might work nice there, weight wont be a downside, regardless flighttimes.
i believe its usable as a conematic platform but there are not a lot costumers for this specific need.


nice adapter design, its skinny, wont work with tpu? your first print was pla?
would be nice to get a comparison about material and vibrations from the log:-)
i used tpu mounts as softmount, dont know how to name that; they was "centered" to the mounting, this might be a difference

Yes, yours is probably the first to show up on the net. A few had popped up on Rotorbuild now. 

It was touted as a micro long range by the designer but the weight and lack of GPS mount, design to fit DJI Air Unit probably makes it more an " efficient " medium range cruiser. 

I was contemplating getting one but decided to build the Micro Apex but I 
look forward to some flight footage and flight time of your Bobcat.

Hi Ronin,

Check out the Proper camera mounts (pic) on the GEPRC Phantom frame of my Phantom-X.

I also have these on the FrankenFly-2-4 (pic).

These are the Armattan Tadpole Aluminum Cam Brace that I get from PyroDrone. 

They are a little pricey, but they are extremely light, work quite well, and look cool
