This is a little how-to guide for making your own cheap motor mounts for round tubes (arms) with vibration absorbtion. Keep in mind that this motor mount is made for a AX-2210N brushless motor. It will use a mounting plate of 4x4cm.
Take the arm and glue 2 short pieces of the exact same tube. I use 14mm carbon tubes but you can do it with alu tubes as well. If you have high quality (very strong) epoxy than you can just glue everything togheter. If you do not have epoxy or medium quality glue then glue the parts togheter and add some extra screws in the next step.
The anti vibration rubbers are computer case fan mounting rubbers. The first batch I bought for my previous quad project came from xilence the second batch I bought for the Y6 project came from ekl. (where to buy)
+ lightweight, the 2 short pieces of extra carbon tube, the 2 carbon plates and the anti vibration rubbers are only just several grams all togheter.
+ easy to build
+ reduces vibration
- parts are glued togheter, so you can't replace or change individual pieces.
- does look diy :)
