Add this to the backlog of build pictures that I've had for a while now but only just put up.

Fair Warning. No one likes building this frame.
This is a structural stack frame meaning the electronics stack is sandwhiched between the top frame and bottom frame portions. This makes the build a little awkward. This also means that replacing or working on any of the internal components in the stack usually requires taking it completely apart.

Tired of complaining yet? Ok, Good.

This little quad will run 3" and 4" props. Most people are running 1404 3600kv motors although some have gone up to a 1407 with some frame mods.
If you run RX1404 3600kv motors on 3" props it's exceptionally quiet as well as being under 250g which lifts alot of the restrictions on where you can and can't fly.
with the GoPro Session it tops out at 274g. Use your discression as to where you fly.
(This setup is running a Runcam Eagle Micro as well as a full-size TBS Unify HV so there are weight savings to be found if you are really trying to get sub 250g and still drag around a GoPro Session.)

The AIO flight controller/4in1 ESC helps with the weight savings although some people have shown them to have short lifespan. (they do not like 4s and 6500kv motors - true story).

There are some more detailed pictures in another build of mine with the GoPro print showing interal FC/VTX/RX wiring . Those can be found here:

There are two additional pictures included in this documentation. One shows how much you need to drill out the frame at the motor locations IF you are using the RotorX 1404v2 series motors as the shaft c-clip protrudes more. The other picture is a demonstration of bending screw in a structural stack when you disarm at 100ft onto a fence post.

Hopefully the pictures help with anothers build process.

Very nice! Wish I tried this setup when I had mine. How's it fly?

It's not bad actually. As long as you fly it for what it is you are fine. The GoPro does drag down the performance and change it's rotational center but for swooping around it does just fine! Pretty smooth flier. Just remember the throttle response is a bit less.

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..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
