DB that just means you have shed loads of props in the first place ;-)

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

High Level of Mechanical vibration ?

I';m trying to identify the source of vibration when using my RCTimer gimbal

As a base line test i just bolted the camera direct to the frame it see how vibration compared to the gimbal

result is here

Question is does this look typical for a direct mount or is there a lot of mechanical vibration ?

footage with same camera on the under slung gimbal is here for comparison

Here is footage of my Y6 with a GoPro hard mounted on the top.  No balancing to the props or motors.



My guess is that you have either a motor problem (balance/bearings/bent shaft) or a prop balance problem.  It is possible that it is a combination of all of these.

Thanks. I';m 90% certain at least one motor has a bent shaft if not two after couple of good impacts hence trying to decide if i replace like for like or upgrade to tigers with any eye on the future.

Very useful to see your footage as reference

Another reason to go with the tigers is that you can get spare shafts if you do bend them.

I have bent the prop adapters before and thought I had bent motor shafts. Might be worth spinning up the motors without any on to see what the shafts are like.

I gave this a go over the weekend. Fraction smoother with them off.

Biggest thing was that with props i could hear one of the motors growling like mad which kind of points to shot bearings.

I like to spin them up to max throttle just sitting in their mount on the bench. No prop holder, washer or nut on the shaft.

If they fall over or jump or make buzzing noises pass them over for quad work. Maybe they';re good enough for a plane or heli but not a multi.
