I have been messing with the quadcopter lately and since rebuilding it from the last crash, I decided to take more measures to eliminate or at least dampen some of the vibration I have been experiencing on the GoPro camera. First I dynamically balanced all the props using a laser from the idea I found on flitetest.
This helped out however I was still getting more vibration then I would like. I recently heard an idea on thecrashcast podcast where people were using Moongels to dampen vibrations. Moongels are a product marketed towards drummers who want to eliminate some of the excess ringing on their drums. I decided to give this idea a try.
I must confess, I lied took the cheap way out as I didn't use use actual moongels, but rather used those sticky toy things you often find at grocery stores in the front where they have all the candy/toy dispensors for kids. As I understand it, this is the same material used in moongels.
Here is how I did the assembly. Meet Roswell, Roswell is going to sacrifice himself for the better of FPV video everywhere...
The next thing I did was to make a separate plate to hold the gopro mount itself, I then sandwiched the pieces of the toy between the new plate and the plate on the quad. I also noticed the buckle for the go-pro had more play in it then I would like, so I used some small pieces of electrical tape to make it fit tighter...
Here is the finished result ready to fly!
Lastly, the results. I made this before and after video to illustrate the difference. I feel this improved things greatly, see for youself...
