Shendrones Mixuko build

[C0d3M0nk3y]

I like the build, Code. Looking forward to seeing more progression pictures of this frame.

Thanks man.

 

[C0d3M0nk3y]

I'm using the KISS 24A ESCs on this build.



I have everything soldered to the PDB and covered with some liquid electrical tape. The zip tie is to add some strain relief for the battery connector.



Here's a closer look.

Nice fitting work there. I'm surprised though at the 24 amp esc's How much power you expecting to pump thru that tiny thing? Also.. is there a heat sink on the back of those ESC's or they bare pcb? I'm looking to up the size on my Versa soon so I can more safely switch to 4s later.

Wow just looked them up on getfpv.. 24 dollars each. Them are some serious controllers.

I haven't used these motors yet, but I expect to draw over 20 amps per motor with 3 blade 5" props on 4S.

No heat sink.

They cost a little less depending on exchange rate when ordered directly from flyduino.

Motors mounted.

 

[C0d3M0nk3y]

I'm using the KISS FC.



Here's the FC with the signal, ground, and telemetry wires from the ESCs soldered. I also soldered on a buzzer and the connector for the receiver.

 

[C0d3M0nk3y]

I added 8 mm standoffs to mount the FC.



I'm mounting an XSR receiver between the PDB and FC. I put a layer of foam tape on top and bottom of the rx to add a little padding. I also added an o-ring on each standoff.



Then I could mount the FC and finish the center stack with a nylon nut on each standoff.

 

[PsyBorg]

Wow someone was busy since I last checked on this. Time for new round of noob questions.

How come you put the receiver in between the PDB and FC? I would think you would want that as far from a current pulsing entity as possible to avoid interference that I assume would be around the PDB more then anywhere on the project.

Be interesting to see an EM spectrograph while that is working with all that sitting so close together.

Other then that it is coming along nicely. You got a lot done this round.

I wanted it low to route the antennas, I've mounted receivers between PDB and FC before without issues, and that's where Shendrones recommends mounting the receiver in their build guide.

Thanks.

 

[C0d3M0nk3y]

My plan to use shorter spacers for the FPV pod didn't work out. My center stack ended up being about 2 or 3 mm too tall. I have to use 30 mm spacers, but I'm still using black nylon ones.



With the wiring all routed around the spacers, I can secure the ESCs in place.

how Does the kiss fc fit in the frame its a bit more compact than the naze32(rev 6,5) but been wondering how small it is.

It fits perfectly. The mounting holes are in the same location as other boards, but there are cutouts on the front and back.

Looking good man, I always enjoy your builds. Question for ya, where did you source your 30mm standoffs? I need to some for a couple builds in progress, but I can't find any in the US. I'm going on vacation in a few weeks and I'd like to bring the new quads with me, but I'm not sure if China will get them to me fast enough.

I found some on amazon. I'm not sure if I like them because the hole is only about 10 mm deep on each side and the middle is solid. MRSS sells them too.

 

[Flat4]

Awesome, thanks. MRSS it is, not sure if I care for solid ones either, kind of defeats the purpose of using them for weight savings. Besides I've always had them shear near the screw anyways, so I don't think any real strength will be gained over the ones that are threaded all the way through.

 

[C0d3M0nk3y]

I soldered on a connector for the FPV camera. I added a 12 V regulator just in case the vtx output voltage dips below 5 V. I also ran the RC antennas up the back posts on zip ties.



FPV pod attached. I used an o-ring on the SMA connector to help hold the vtx in place. There's also a layer of foam tape between the vtx and the FC.



Added a set of HQ 5x4x3 props.

 

[C0d3M0nk3y]

I cut a piece of sticky back neoprene to fit on the bottom plate to help hold the battery in place.

The dry weight is 295 g.



With a Lumenier 1300 4S, the AUW is 448 g.

And here's what it looks like:

Sweet build! can we all start chanting "maiden" now?
