I've seen photos, but I'm still surprised at how tiny this thing is.

Needs 2206/2100kv cobras

This looks like a lot of fun btw... I'm seeing a lot of the 180 frames gaining popularity in the local FPV group here in Atlanta, but nothing this small. Armattan makes quality frames as well.

6 cell?

 

[C0d3M0nk3y]

Needs 2206/2100kv cobras

Are these close enough?



The packaging says they're 4000 KV.

Here's one next to an 1806 and a 2204 for comparison:

Armattan makes quality frames as well.

I don't think Armattan is actually making them. There are 3 or 4 sites I've seen selling these.

 

[C0d3M0nk3y]

6 cell?

Not quite.

 

[C0d3M0nk3y]

I'll be using RotorX 3020 props and SN20a ESCs. I'll probably run SimonK on the ESCs because some of the RotorX guys have had trouble with BLHeli with these motors.

 

[narcolepticltd]

those motors are just the right size for me to stick up my nose... I'm not responsible or mature enough for this particular copter

Sweet!!!!

I've been wanting to build something small like this for months, but I made the mistake of ordering some DYS 1306 2300kv motors when I probably should have ordered the 3100kv motors.

What made you opt for the 1104 motors for this build?

 

[C0d3M0nk3y]

Sweet!!!!

Thanks!

What made you opt for the 1104 motors for this build?

I'm going to try to keep it as light as I can.

I could see this size racing inside an old beatup racquetball court.

And I thought 1806 motors were small. I'm looking forward to seeing your progress!

Oooh... something like that would be pretty rad.

Thanks. This build is definitely going to be a challenge for me. I've cut weight on some things on my other builds, but I've never really went after every possible gram.

 

[C0d3M0nk3y]

Test fit of the hardware:



The frame comes with nylon bolts for the standoffs, but I replaced them with some aluminum bolts I had. They didn't add any measurable amount of weight (by my scale anyway).

Speaking of weight, the bare frame is 25 g.

 

[Spastickitten]

Will it even hold a gopro?

 

[C0d3M0nk3y]

Will it even hold a gopro?

No, there's no way it will lift a GoPro.

 

[narcolepticltd]

No, there's no way it will lift a GoPro.

time to buy a Session... that way you can film every dust bunny on top of the book case as you zoom through just under the ceiling.

 

[Spastickitten]

don't hit them, you might break a prop!
