With the 3M dual lock you can add anything to your quadcopter from batteries (in addition to straps), receivers, transmitters etc. It's strong, detachable and very easy to use. Just cut the right size for both parts you wish to connect and lock it! I used it for my battery. Stick some on the frame and battery and click, strap it and you are ready tot go! Also my receiver is sticked to the frame this way :) I just love it! For smaller parts (< 1 cm2) it might be unasble. Other non-detachable stuff would be better off using double-sided tape.
Just stepped into the world of FPV Racing. This blog contains my findings along the way!
