I Can't Believe it! MY "New & Improved" shell has a crack after 7 flights!

By mechanic I mean I look at everything mechanically.
I can build a house, work with sheet metal, electric, plumbing, quads and most other things.

I'd consider balancing props on a homemade quad with aftermarket props - but the QC on the Phantom props has proven itself (IMHO) to be quite good.

I do have experience with other quads and how the props vibrate and look when they are out of balance or the shafts are bent, etc - that's a different matter.

DJI has 100's of engineers - many of them aeronautical specialists. If they wanted us to balance the props they'd probably say so.
I seriously doubt these 100's of engineers are checking all the props individually. That's my job and my sample has not been perfect.
The engineers also designed the shell that has worked pretty well most of the time. I added Strong Arm reinforcement plates to help distribute the loads. Maybe not necessary, but it can't hurt and might help.

You are certainly right - but add in the lack of ability of the average person to "balance their props or hubs" and you might just have people making things worse...

If folks want to balance their props - more power to them! On the other hand, we should deal in facts here and with 1 million DJI Camera/gimbal models out there, I doubt 1 or 2% balance their props - and yet the vast majority have very stable video.

The question isn't whether you can find something off-balance. Among the many questions are:
1. What % of users can find and fix such things easily?
2. What is the effect on the P3 when things are a little off?
3. Etc.

Getting to the OP or to most people with video problems - it may be their best course of action is just to try another pack of props...they are cheap enough...to get that variable out of the way.
 
Unbalanced props are almost no factor in video issues if video setting set properly.

Unbalanced Props may not result into video issues as such props create vibrations on the shell. Gimbals are designed to take care of the tilts etc but if they are subjected to continuous vibrations, life of the gimbal vibration pads will get reduced and finally will result into their failures and that will result into poor video. No idea, how long will it take to affect the gimbal pads. If the vibration frequency matches with the critical frequency of the hardware, things will fail in no time.

You may be correct, although I imagine people not willing to learn and balance props correctly, probably wouldn't balance them anyway. Even though it certainly isn't rocket science.
Dji seems to have their gimbals well isolated from any vibration--I don't think I have ever read a jello thread.
Streve made a very good case for balancing in this thread. Check his reply #122
BTW: I'm not saying the Dji props aren't usually very close, but I have always been able to make them a little better. And my common sense tells me that's a good thing when the prop will be spinning at ~10,000 RPM.

There are quite a few posts about jello.. but all are eliminated by proper video settings.

About the gimble isolators... i just replaced on after close to 300 flights and 600000ft traveled.
