Cerberus Trifecta - Cerb v2 newbe build

That should work, I usually use o-rings on a long screw.

This is a great thread, learning a lot from it. Green and Vv, can you post a picture of soft mounted stack in your collection?

 

[theGreenOrange]

Here is one

 

[HighTechPauper]

Makes sense. Are you using thread locker on the nuts at the top?

 

[theGreenOrange]

Nah, the compression of the o-rings keeps them tight.

 

[HighTechPauper]

Thanks Green!

 

[HighTechPauper]

What is the method of soft mounting motors you guys use? Silicone Anti Vibration pads or O-rings or...?

 

[Futuramille]

here's what I did with the motors. I'm expecting criticism so bring it please! I have found that this one sided foam (cheap in crafts at wally world in multiple colors) worked well for me in several past instances. In this case it was easier to cut out to shape. I was again concerned about airflow plus accessibility to that motor cap screw. its foamy but will take some compression. Still need Loctite. (I first used and removed 3m double sided tape. It looked like over time it could move into the motors when hot). its not a very stout foam though and may have longevity issues. I've done two motors with Loctite, the last two is where I am in the build. I'm giving it a day and then I'll test a screw to validate my Loctite is holding.

thanks green, looking at that shot, i should at least put the o rings on either side of the FC. plus now i want virtues red gummies.

[Futuramille]

I'm sure there are a plethora of solutions. what do y'all use to softmount motors? do you mind a sticky side against the motor? what does heat do to these mounts over time?

 

[HighTechPauper]

Seems like your soft mount motor approach should work good, no critique here.

Green, i notice your using the plastic nuts on top of the stack. you mentioned no loctite needed. should i loctite my metel top nuts, or go with the plastic ones... i have both

 

[Futuramille]

thanks all for sharing this build with me. now were waiting on esc covers. i hope they fit the look I'm wanting.
i really just want to start soldering this together sigh, but ill wait.
when the 2" cerb arrives im going to be a bit preoccupied but that package will have the esc covers.
lots to do still

 

[VirtueViolater]

If you use the gummies, motor dampening is not needed

 

[theGreenOrange]

I like to use silicone motor pads. Not sure it is needed but it doesn't hurt. If silicone isn't available I use TPU. For the stack, I use all nylon hardware with no loctite or anything special.

 

[Wayno52]

I use loctite at work for certain super hard working construction machinery, not sure it is a great idea for that application. Just my opinion though.

next... you see what my new challenge was... I found those small o rings to "soft mount" the FC in a bag of helicopter mainblade hubs. I got exactly 4 small thinner ones (hornet 2) and four thicker ones (shogun v2) and quit digging.
next great conversation is yalls take on "soft mounting". I haven't locktighted those top stack nuts so this is still all retrofit.

(I also did the motors but we'll come to that)

what do ya'll do in this regard?View attachment 1408

Futura,

Looks like you're getting along pretty good on this build. One thing you could consider is dropping the height of your stack a bit. It looks like you've got quite a bit of room between the PDB and FC. You may be able to get away with a screw/bolt as the standoff and a few o-rings for softmounting and spacing. Doing away with the nylon standoff. I don't know how it all solders up so you may need all of that room for your soldering. RaceFlight makes some "gummies" for softmounting their FC's that have worked really well for me to use to softmount other boards. They can be placed between boards and in some cases can be cut in half to conserve space. Here's a link:
