I have just edited the quadrotor tag, and added suggested text for both the excerpt and full tag wiki, which were lacking. However, I then noticed that there was also a quadcoptor tag (which I must say, already has a very informative description).
Are they not, essentially, one and the same thing? If there is a significant difference, then they should be edited to specify when to use each one. Otherwise, should they not be merged?
Maybe I have actually suggested the incorrect text, and actually made them sound like the same thing, in which case I apologise. If I have not, then maybe a rethink is required, with respect to these two synonymous tags.
Out of interest, at the time of writing,
quadrotor is tagged 67 times, and
quadcopter 228 times.
