Nice video Jordan! It remembered me of those times when I was 12 and combined my electrical cord remote toys to create new ones. This days the results can get way better.

You can buy the receiver, motors and transmitter for CX-31 online for less than the total product (about 25$) and print a superior frame. I would recommend using a grid infill with a think shell and 5%. Also try adding weight to frame in the center creating more resistance to wobble. For this I recommend a uniform but small piece of metal like a lead bead. In real aircraft depleted uranium is used. But in this case a light fishing weight.

[@drew6017]

The wobbling was caused by the change in geometry and weight balance (most likely the removal of the ducts around the propellers and lower overall weight). The quad stabilized because the PID controller eventually adjusted to the new state of the quad. To fix it you would have to change the PID values of the flight controller or correct the geometry to better match the original quad.

When you reprint it, are you going to make places for the board and battery? That should help too when you fly it.

[@johnabernethy5736]

I agree with Bartłomiej Noga. The controller is over-correcting, then over-correcting for it's over-correction, resulting in oscillations, giving it that wobbly feel. I don't know if there's a way to access the firmware on one of these and adjust the PID. Maybe you could give it more weight, compromise between the original heavy saucer body and the feather-weight frame (if you still have it; I just realized how old this upload is).

[@benbubeck1305]

bake a pla print at 110 C for about 20 minutes. Let it slowly aircool.

[@bartomiejnoga1804]

It doesn't work because PIDs are made for other configuration. Without weight it's to responsive, so steering doesn't work. I don't know if you can program it, but it won't work even with other frame, unless it'll be some about same weight. Also you should think about tunnels for props, because they work probably like kind of EDF.

[@harrisonwenig7845]

This was awesome!!! Do 10000000000 more of these videos please!

[@prcdslnc13]

That frame should be no issue in abs. What printer are you using, and what bed material?

[@prcdslnc13]

Ok that explains a lot. Its hard to fight the internal stresses of ABS without heat. Good luck!

[@CezarCociorba]

3D printing done right

[@AkshatShenoy]

Nice!

[@hughnorman6270]

The wobbling might be cause by a misalignment of the motors, given they didn't really fit.

[@NicklasEkstrand]

***** The first thing I would check is what is in the way of the air flow. Maybe you need to get the cables tighter to the body? But I think it's pretty cool and a really good first attempt.

[@haydenrc8178]

Or vibration of the fc

[@ElectronicRayyan]

You need some improvements in the quadcopter design and it will work very well

[@DarkMetalSkies]

Shit, now i wanna try that but with the fy326 and a larger frame, thanks Jordan!!

[@DarkMetalSkies]

I think your woobles might come from the fact that the quad's board was designed to account for the shape and weight of the alien ship looking frame and because of that it might not be able to be very stable. Who knows, but when I get my Prusa i3 up and running I'll try it out.

[@evelyndai8200]

Its shaky as the props are supposed to be ducted instead of being left in the open

[@bilaltariq3471]

Its ook
