RE: ATTENTION ALL DF FOLKS!!
They won't create a new forum unless there is a significant amount of info being discussed about a specific topic. You should have seen the 1600+ post thread for the DF before this forum was created. When I found that thread, it took me about a week to catch up on all the info. Different DF topics were spread all over the place in that thread. There is a multi-rotor helo forum at [link=http://www.rcgroups.com/multi-rotor-helis-200/]this[/link] link but it's for all multi-rotor helos with alot of talk mostly about coaxial helos. I don't consider coaxial a multi-rotor because it's still just two rotors like the standard main and tail just has two. Anything with more than two rotors is what I would call multi-rotor.
