Vibration dampening with F550 and aeroxcraft landing gear/gimbal

[aForcefulThrust]

Recently I've been trying to dampen the vibrations going to my nex5n to get more clear shots. Went to the local hardware store and got some longer bolts for my landing gear mount, and a bunch of rubber grommets/washers. This is what I came up with so far.. Rubber inbetween the bolt head and upper frame, rubber inbetween the lower F550/upper landing gear, and rubber inbetween the bottom nut and landing gear. Haven't tested it much yet, hopefully today.

Would it not be better to locate the source of vibration and balance it? Balancing motors and blades is relatively simple but time consuming.

Ever have a bearing go bad? In my experience, once you isolate the camera sufficiently having other variables disturb the footage is much less likely.

I just built the F550 last night and it took me 2 hours to balance the motors. A couple of them were *way* out of balance, even with the stickers removed. They're silky smooth now, so it's definitely worth the time to do it. Ditto your props....if you don't already have one, get yourself a good quality prop balancer (Dubro for eg) and balance them, including the hubs. You'll be surprised how much less vibes you'll have then

How'd you balance your motors 550 motors mrbonk?

Very patiently
I found a seismometer app for the iPhone (called iSeismometer) and used that to analyse the vibes in the airframe, one motor at a time. I'm pretty sure there was a video kicking around on the interwebs at the time, showing a guy using it.

Anyway, I disconnected all but one motor, then took the prop and adaptor off and ran it. I got a piece of tape (I cut small squares of canopy tape) and moved it around on the motor can until I got the least vibes possible, then repeated the process with the prop/adaptor mounted. I also used the Dubro prop balancer to balance the prop *and* adaptor beforehand. Sometimes, I had to move the tape on the motor can after the prop was mounted....probably due to inconsistent prop hubs?

In any case, it was a time consuming process, but worth it for smooth running motors.

Try using silicone spacers insteadead of the rubber one.
I have the same landing gear and i get no jello
