Cosmo - Massive Droner - 3"

By Apeian on Dec 08, 2018

13 14 3

Was looking at this frame for a while, and this is one of the nicest looking and sturdy 3" quads I've seen. But be warned, this build is "TIGHT"..so plan well. Forget about installing a Runcam Split or Caddx Turtle (HD recording) if you dont get an "all in one" fc with ESCs. I wanted solid 4S power, and the AirBlade 4850KV Superman Motors and Airbot Ori 4 In1 25A ESCs certainly deliver. THe EMAX Avan 3" props are awesome...great thrust, stability, and control. Flys good with stock PIDs, going to be tuning when I get some real outdoor time...

Hi Apeian, I would like to make this drone but the frame and antenna, are not in stock. What frame and antenna would you recommend to use instead?

omg how did those props fit that motor. I have a similarly shaped and same 1404 stator size (im using the dys 1404 4300kv) and they dont fit hahah.

Apeian Jan 16, 2019

Hey bud...I thought the same at first...when you screw them on, they bend to the shape of the motor...they work great!!! ;D

Interestingly, I just finished an MMD and I was actually thinking it maybe possible to jam in a split cam. The Ori ESC takes up a lot of height. A stack consisting of Spedix 20A, F411 mini, AKK FX3 and a single split board may fit in using short standoffs along with an XM or R9 mini rx. That would definitely be an exercise in masochism 🤯 I wish they had a better way of attaching the strap because that takes some room as well.

I saw that on your builds and thought it was a great choice if I dump the HD recording. Can't wait to get a nice day over here and post some footage...been LOS flying it up and down the block its an animal..😜.

Winter hasn't even started yet 😭 I have been flying through the cold, a couple of packs at a time. It sucks.
As with HD recoding with the split cameras, you will never get the GoPro quality. Then there's a small matter of pilot skills that make videos worth watching. So I just fly for fun without worrying about video. To each his or her own, I guess.
