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.

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

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
