Armattan Marmotte 5 Inch Cruiser

I recently built a 7 inch quad but I just wasn't happy with how it felt flying, I think 5 inch quads are my sweet spot. I pulled the electronics and used everything but the motors to rebuild my Chameleon Ti. I wasn't interested in long range but still wanted something for slow cruising with extended flight times. I ended up buying another 5 inch Marmotte and used the Xing 2306-1700kv motors on it.

Rather than use race wire I drew up some wire holders/protectors that weigh 2.3 grams each. The rest of the 3D printed parts I designed and printed as well.

With the Gemfan Flash 5149-3 props and a 1300mAh 5S pack I'm getting 8 minutes of flight just slow cruising around using 1000mAh. I'll be trying other tri-blade props and some bi-blade props to see if I can extend the flight time a little longer.

This thing is gorgeous - I randomly ran into somebody at the DCA Airport with one similarly pretty - still can't figure out why I want one in this color scheme so badly.

can you post the thingiverse file for the motor wire protector?

Airmaxx23   Aug 21, 2019 

Yes I can. I'll get them on Thingiverse today or tomorrow and post a link here for you.

did you ever get a chance to post them?

Sorry for the delay, here you go.

Brilliant build love it especially the clean stack with great use of space. If only they made a low version of the marmotte. does the VTX get hot without air flow underneath?? As I may follow you with my current build and mount the rush like that.

Thanks, the VTx stays cool even running at 500mw. Since I have the wires soldered to the pads on the bottom of the VTx I used a spacer under the 2 holes on the VTx where the screws go through. To be safe I put a thin layer of hot glue over the wires so they can't come in contact with the carbon fiber. I then used 2 small pieces of double sided foam tape on the corners where I removed the screw holes on the VTx. I'm adding 2 photos right now that show the motors wired to the ESC and the whole build without the top plate.

Thank you very much for the added pictures. Great instructions, I will be sure to do this on my next build on a low frame. Happy Flying

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..
