For such a simple part, the battery pad can make the difference between a successful flight or a crashed quad. Keep your gear in check with the Ummagrip Battery Pad made by pilot Ummagawd. Originally made for the Remix frame, this pad is now available to everyone! Simply cut it to the size that you need and peel the 3M adhesive to stick on your quad.
To maintain tackiness, just use a damp cloth or sponge and wipe away the lint and dust that has collected over time and you're golden.
