Crashed my mavic - questions

[dajohn17]

Crashed my mavic - looks like I'll be needing a new vibration plate. I have another issue as well with my back left arm, seems a plastic trim has broken off as well in the crash. Is it possible to buy this part or do I need to replace the whole arm? I've attached pictures

Replacement parts show it as being part of the assembly but just curious if it is sold separately and if so any links would be appreciated. Thanks! And it sucks to crash/break this thing [emoji58]

Wonder if he knows if the part is replaceable vs the whole arm? seems like it would be easier to fix the part that prevents the arm from overextending then the whole arm - cheaper too.

Thanks for mentioning me @Anthony Viscomi

The whole arm will need replacing.

Another question: after looking at this it doesnt appear to be a clean break. Maybe I can take it apart and fix it with some glue? Will need to take it apart anyways to get the vibration plate fixed.

Glue = bad idea.

Replace arm = good idea

What's a rough estimate you charge for replacing the rear left arm? Vibration plate? Thanks in advance

I second this sentiment .
Since this area is broken from stress if you glues it and applied the same amount of stress or even less then the piece would break again. Its not like broken bones that actually are stronger at the break after they heal.

New part is a must. Plus you will have piece of mind knowing that the weakest link of your Mavic Pro is not a spot of glue that may or may not hold.

Thanks, I found a place nearby that sells parts for $26!

Not used it on a mavic but I use loctite 431 a lot and parts have never broken at the glued joint, I have had things break again but not in the same place

obviously a new arm will always be the best choice but saying all glue joints are bad IMO is wrong

Its and un necessary risk for a high speed flying machine.

Yes also Loctite 416 which is same thing with higher viscosity. If the break fits back together with close tolerance, is not otherwise deformed and is clean a good Cyanoacrylite glue will create a joint as strong, or stronger than the original part. They don’t call it “crazy glue” for nothing. Just don’t get your fingers in there or you’ll have to cut them loose

 

[BD0G]

This is only true if the force exhibited on the joint is in a vertical (up and down) direction. Side to side movement known as sheer will allow the joint to separate.

The guy with the hardhat that is glue to a large industrial I beam in the commercial is only held suspended as his weight is pulling straight down. There is no side to side sheer forces that are being exhibited. If the same experiment is conducted and he grabs the hard hat and rocks back and forth while twisting he will inevitably fall from the I beam with the Helmet in his hands.

 

[kcabpilot]

The datasheet for Loctite 416 lists the shear strength as 3200 psi

LOCTITE 416 - Viscous, general purpose, ethyl-based instant adhesive - Henkel

 

[BD0G]

Wow! Phenominal. The replacement part is just a bit more than a tube of the Loctite 416 so why not splurge a little and replace with factory new part?

I guess the time and trouble to disassemble , reassemble would be one drawback.

Right, Just saying it's a viable option, one that takes about 30 seconds and probably preferable to someone who might not be comfortable taking their Mavic apart and soldering wires onto the board. I Personally don't have a problem replacing the arm but my assessment of the damage deemed that it was unnecessary to do so. Plus I already had the glue because this in not the first thing in my possession that I have ever broken nor will it likely be the last so obviously there are other uses for it. But I get your point.
