Skid plates for quadcopters with underslung lipo batteries. just stops damage to the lipo.. fits most 1300-1500 mAh batteries and I made single and dual strap versions as I have both .. single strap is 22mm slot which will take most straps, all mine are 20mm.. the dual strap is 18mm slot .. my dual straps are 16mm wide.
