Laser cut foldable quad frame build version 2


Junior Member
Hey guys,

I wanted to share my laser cut quad frame build with you to get some design input and gauge interest in this type of design. My version 1 can be found at and

I've gone over the improvements of my design in this post:

All of the part are bamboo built by ponoko and my original design challenge was to make a cheap frame that required only minimal of hardware to build: M3 screws, zipties and nylon spacers (both cheap and one very easy to source).

So let's build!

I used metal M3 hex screws to assemble the quad pivot.

Trying to get some tension on the zipties to hold the landing gear securely

Secured the ESC to the plate using zipties

The two bottom ESCs are ready, feeding the top two ESCs through.

Secured the top ESCs with zipties and completed the core assembly using nylon spacers

The bottom plate has a convenient Velcro strap anchor for the battery.

Here is a side view of the completed ESC sandwich. I use a lynchpin to secure the Quad for flight since it can be folded.

Placed the KK board on some foam (from its packaging) and mounted it using some leftover zipties.

Used zipties to cleanup the cabling, the booms have little ziptie anchors that make this very easy. In this build I used spare zipties terminators to give it a nice clean finish like on the landing gear.

Secured the RX using a ziptie and a leftover ziptie anchor.

The gopro fits perfectly between the plates (I have a nice collection of nylon spacers to achieve this). The Velcro strap keeps it safe here... This wasn't my design intent but it's a nice little feature, I will test its robustness on my maiden.

WOW, this is awesome! Is the quad sturdy enough? I would believe that the round slots made it kind of fragile... Maybe not?

How are those three blade props working for you?

Yup, the material is definitely sturdy enough. Caveat: it can't obviously match 10mm booms but I was pleasantly surprised. The 3 blade props are working fine. They were cheap on HK ;).

I DO like the motor mounting method a lot!

Note to self: GET my ShapeOko set up and cut something!
