prop balancing issue.

I guess i need to fly the quad already and see how the camera is working...most all of them have a very bad jello effect and only after a prop balance does it go away or some home made cushioning for the camera...Id prefer to have somewhat balanced props instead...The video seemed pretty straight forward using the same cheap balancer..just sucks its not turning out as easy as the video was.

I might just try aluminum tape so it takes alot less if all else fails.

Is it better to add the tape to the top or the underside of the prop?

Does not make too much difference though I like top just because of the shape. Try very ard to avoid messing up the airfoil shape.
 
I bought some aluminum tape and gave it another go...This time went to the top of the blade with the tape...i think this is about as good as i can get a prop for now..I'll do the other 3 later tonight after work and see how it flies tomorrow.

Looks too intense. Did you do any sanding of the heavy side? Did you check to see if the naked balance rod assembly is actually balanced?
 
Just did one more prop and the heavy side was the non letter side again..this one took less tape however.

I spun each prop nut centered on the shaft and marked the low side..it never lands in the same spot so im not sure they are that much out of balance.
 
Hi,
had to sing up here because I just ditched the magnetic balancer (carbon fiber ends, three red bards holding it together etc). My claim is that the magnets are the problem. I never got consistent results on 8" (Phantom 1, 8045) props! I'm thinking that the magnets hold on too tight on the spindle. The other end has a gap to the magnet, but still. The magnetic field does something strange. I even added a drop of oil to the end of the spindle to make sure it's not mechanical friction.

Last night I got it. I cut a 300 mm bronze tube in two tubes, drilled two 4 mm holes at the end of my storage shelve chipboard 40 mm apart, plugged two bronze tubes in and let the splindle-locknut-prob assy lay on the tubes. Pretty much the same as the drinking glass balancer, but this one's a fixed stand on my eye level, away from walking path etc. Now it feels too sensitive, moving my hand near the prop causes it to move :) But I think I get the job done. I made a Google Slide out of it, hopefully attaching the JPG image out of it correctly (EDIT: nope, doesn't work, here's the link): https://goo.gl/photos/S4CQXNmsz2fBzUKs7

About the plastic mold propellers in general: I previously balanced two propellers from the same manufacturer and the same set, and they both had the same off-balance. It's possible to have a dozen from the same manufacturer, and they're all can be similarly, precisely (LOL) off.
 
So I got an ideafly mars 350 and it has a fast oscillation that would make it impossible to take pictures. the gimble could never keep up. could out of balance props be the culprit in such a scenario? The mars 350 uses dji 9450 props. When i see reviews of this quad, i never see them dealing with such issues, so my assumption is that it is something else. I bought a dubro balancer and am waiting on the machined shaft to put the props on.
