Large CP Tricopter

A video of a huge collective pitch tricopter.

Holy Cow!

I don't think he knows it, but he needs a KK2 really bad.  Forget about the Arduino!

...Tiger

 

No, he doesn't need a KK2.  He needs his head examined.  Why on earth would you screw together three helicopter frames with all the fragile moving parts when a single brushless motor does the same thing?  If you crash one 450 helicopter you are looking at a evening's worth of repairs and adjustments not to mention all the various parts you'll need before you can get back to flying.  With that thing you crash once and you get triple the damage.  Now it's not one feather shaft it's three and maybe three main shafts.  How much for main blades?  Maybe that thing seemed like a good idea once upon a time but I can't see it.  On the other hand the video was uploaded three years ago so maybe back then that's what you had to do.

 

I guess my next build project comes with a head examination 

Cause I want to do one of these, but not three whole helicopters, and no electronics, and 12 channels, I think it can be done a lot more simple, one way to find out  ;D

 

I can't imagine anyone doing it now like that guy did.  There are several different variable pitch enabled brushless motors on the market that probably weren't available three years ago when that guy built that.  I know I've posted some, but just in case here is an example:

Yeah, we have talked about those before, I am interested in something a bit larger. I worked up some CAD drawings last night. Once I get something machined I will start a build thread. But also waiting on a HobbyKing China order for parts. Might take a while.

 

Cool.  I'd like to see what you've cooked up.

 

LOL, I noticed that also but didn't mention it.  Funny how even the dog knew to get the heck out of there.  Maybe he saw some previous iterations of that contraption?
