At our hackerspace we were working on a DIY Quadcopter project. We build the structure using one Berkley ment box, grills, bottoms of energy drink or soda cans, plastic for affixing motors to bottom of cans . Basically with these parts the quadcopter was heavy. We were looking for a lightweight , flexible material to replace bottoms and plastic to keep motors in place. So we figured that we should use a magic material that was "Sugru"
Step 1: Replacing the Motors Place
So we were using bottoms of cans. The aluminium part was great for fixation with screws but was a bit heavy.
So what we did with that ?
We got a small piece of cartboard with dimensions 65x50 mm. The cartboard didnt rezist with pressure of motors. So we applied a thin laywer of sugru at cartboard and mounted to the structure. The new one was better and resisted the pressuer of motors on full load
Step 2: Replacing the Plastic That Keeps Motors in Center
So our motors were fixed in 3 points with screws by plastic. This material was not flexible and our quadcopter was doing noise while we were testing. So we replaced the plastic with sugru. So the motor was buffered because the material was flexible. The most important part was that we had less noise
