I think if planes were weighed before, and the "removable" items (for electrics) were weighed and tagged then that would be acceptable. Therefore the scale/weigh system during the contest doesn't have to be done. Not even spot checks. If it's an electric, a person could be assigned to check the tags of the planes before or after flight this way, as the plane weighed in at the check in day with the tagged batteries (including rec packs) so as long as the tagged packs were in, then you know it's good. The tags could be a weird zip tie or something around the wires that couldn't be removed and put on another pack.

Either way, I'll follow whatever you lay out as a rule.. Don't make me no difference.
