Team pyrodrone been using this dual loock method for years with great luck
The only downside of this dual lock pads is the price.
A roll of this 3M dual lock can cost easily up to 39$, but not any more.
We found the source of these with a reasonable price and now proud to provide you what we’ve been using for a long time.

The package includes 5 pairs (10 piece), which is enought for a drone and 9 batteries.

For best results it is recommended to use a full pad on 5″ quads, you can cut to smaller pcs. if you are using them on lighter batteries for 2-3″ builds.

Dimensions of each pad:
2″x1″
