I had a discussion about removal of the washout arm pins from Mini Protos some time ago. Here's my method using ball link pliers. You can easily push the pin out of the arm with 1.5mm allen wrench or hex screwdriver this way.

Since I had no real use for my Dremel case and had no mCPx case at the same time, I made this. It fits my laptop bag just right.

Charger and the AC adapter are fixed in place with 3M™ Dual Lock as well as batteries will be, once the CNC battery mount comes from Astroid Designs. There's some place left luckily, so a 6V BEC and a 2S LiPo pack will fit for charging while out in the woods.
