I was looking for a "tidy" way to hold my ESC in my T-Rex, and after looking through a "junk" box of household fixings - found these clip type cable holders.

They dont even register on my scale (which goes to 1 gram) so are pretty light

these have a double sided tape fixing system , so just just stick 'em where they need to go , they open up at the top and "snap" back together to hold the wires in place AND they are stand-off - so I get plenty of air around my ESC ...

anyway - they do the job nicely!!!

here it is shown open - and closed.......they are just what I needed in this instance so thought I'd share
