"Hi every one.
I want to upgrade my Heli to a 5 blade rotor head, but i was wondering if i have to change the tail rotor to."

Brandon Angelo replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"hey sorry for the delay, havetn been pn this site much. this is for a research project and we determined that it would make sense to put off the construction of the quadrotor and get the´meat´ of the project started on a tradition heli…"

"As a photo taking platform, they are great, we use two of them.
The octocopter is probably where we would start if we were starting today, the extra lift available and possible save situation with one engine out would be great.
Have to save the…"
Caleb Chamberlain replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Naw! Build one! For a rotorcraft UAV they are awesome. There is enough open-source stuff out there that you could build one without having to invest too much time developing a control board for it."
Gian Carlo M. replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Ok, I'm starting to get discouraged about building a quadcopter... :)"
Caleb Chamberlain replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Xander,
Good points; I'll touch on each of them:
You wrote, "I've seen quadrotors get near 30 min of flight time, something I have not seen in an electric heli (maybe they can get there, but I doubt they can do much…"
Gian Carlo M. replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Xander, that's a great video!
Maybe I was wrong about the maneuverability!"
Xander replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Caleb, I've got to question your assertions. I've seen quadrotors get near 30 min of flight time, something I have not seen in an electric heli (maybe they can get there, but I doubt they can do much better). And while they might not match…"
Jack Crossfire replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Around here we're mostly interested in autonomous systems & not model building for its own sake, so in terms of an autonomous system, the fact that it's a quad rotor isn't the limiting factor in maneuverability."
Caleb Chamberlain replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"It seems to me that the real advantage of a quadrotor is its mechanical simplicity; it makes a fantastic test platform as far as rotorcraft go, since a crash isn't as big a deal as if you crashed a heli.
But in my experience a quadrotor is…"
Gian Carlo M. replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"I don't fly Quads but I intend on building one, and one of the things that bother me about them is the lack of maneuverability. I see a bunch of videos of them but I end up thinking...: boring (except for the FPVs).
That's another reason…"
Michael Molloy replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Belts were a concern and the complexity that goes with them, but i was also concerned with the pitch control linkages, grips etc, one bump of a blade can damage all those mechanisms, a motor prop saver and prop would be alot less complex.."
Brandon Angelo replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"hmmm. I can see the belts causing some concern, but where else can you see the system failing?"
Michael Molloy replied to Brandon Angelo's discussion variable pitch quadrotor-please provide some feedback"Sound very cool, but from a systems safety approach i can see MANY points of failure and a very complex system and I think it would end being heavier and less efficent than just having the motors out on the booms, there are some light motors out…"
Brandon Angelo posted a discussionvariable pitch quadrotor-please provide some feedback
hello all!My name is Brandon and i am a student in la hoping to put together a simple but reliable quadrotor for a research project this summer. I have been flying rc helis for a couple years now and have gotten intimately familiar with the variable-pitch setup. After flying a few novelty 'toy' quadrotors i was left impressed with how easy it was to fly but quite unimpressed with the overall maneuverability of the crafthere are my goals for the build and the research project:Super Stable AND…See More
