I sold 200 sets of these over the last months and then my listing ended because ebay is weird. Here's the new relisting.

COLORS:
I currently have RED and BLUE NinjaFlex Filament, The default is RED but I'll ship BLUE if you want it and leave a note.

-for normal sized racing quad motors : 22xx or 23xx etc. I can make it 18xx size but you have to ask me. **For 1306 or 1407 see here: http://www.ebay.com/itm/-/252941878210? 
-  Real NinjaFlex filament - the softest TPU out there
-  No wasted material or excess weight
-  1.5mm thick
-  0.27g each

Getting some jitters? This is a simple way to dampen those high frequency vibrations resonating through your carbon frame and confusing your Flight Controller. Simply stick these squishy things between your frame and your motors. Tighten screws like normal. 

*** Non-US people: Ebay seems to give you a huge shipping cost. I'm not sure why, but I'll mail for FREE. You'll just have to paypal me directly and include your address.

Samm Sheperd here. I designed, printed, and tested these before Johnny made the idea go viral. I recently tried his electrical tape method and just hated trying to cut and trim excess tape and it ended up being a lot more work with excessive weight and material.

I'm including 8 pieces to make the postage less of a factor and so that you can put them on two quads or whatever.

I'll even write you a letter :)

If you are able, I put the STL file on thingiverse for you to print yourself. I'm not allowed to post the link but just google "thing # 2018045"
