Hi,
I've been using locally available double tape and even some 3M tapes for mounting electronics on my quad (like esc, vtx, battery monitor). They work well, but removing them is a PAIN and they always leave behind sticky residue that is hard to remove. Most times, part of the tape tears and remains behind as well! Super annoying for me.

Does anyone have any suggestions of good tape to use that sticks well but comes off easy, leaving no residue behind, for mounting my electronics?
Any suggestions of alternate methods of mounting components?

Yes it happens and is really annoying.

Try using velcro tape. It will make it more tidy and organised.
