"Mike,
It is funny that I just read your comment here since I started a project back in December to build a variable pitch hex copter using 450 tail assemblies. (single motor) I just finished putting the assembly together and have begun…"

Hey guys,I'm building a larger quadcopter for a project. I have all the construction down and everything like that, just having some trouble with the code. I was wondering if anyone knew if you can…Continue

Hey guys,two questions on this topic:1.I just would like to know if anyone is using, or knows how to use, the ardupilot Mega 2.5 to just stabilize a quad copter so that i can drive it while the…Continue

ABSimon replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"Hello Harry,
yes, currently we work on an variable pitch quadrocopters
But we are still working on it (it fly's since ~ two weekends :))
Under the video on youtube, you find some data about the model.
Best Regards

Nathan Rae replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"Hi Harry,
I've been following this along and I was wondering what it was you were aiming to lift with the beast of a Multi Copter you are building? Are you going to be lifting and placing breeze blocks or timber for the construction…"
Mike Klinker replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"The frame was a custom cut carbon fiber foam core.
The variable pitch system I believe is posted somewhere in this forum but I can find it if you need it.
The motor in the middle is difficult. They tried that paired with trex 450 tail…"
Ireck Briones replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"Mike,
The project looks very interesting. What was the frame based off of? I wanted to try and replicate this project for myself and it would be nice to use all the same parts. My intent is to do something slightly different though and use only one…"

I don't know why or what i can do with it (except crashing), but i want that!

Brad Hughey replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"Vibration is the unfortunate bane of every lifting airscrew. I know some engineers invest virtually their entire careers in this field on full-scale single-rotor choppers.
Which brings me to my next point about variable vs. fixed pitch -…"
Mike Klinker replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"Harry,
In terms of flight planner and code, I believe that the quad was using this board with 'custom' code on it. One thing you have to remember is that it was flown indoors using a VICON system for position and velocity data.…"
Harry Hubbert replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"Thanks mike,
Do have a few questions, what did you use for the flight planner/code? i cant find out if the arducopter flight planner and code of the ardupilot Mega works with variable pitch or how to make it work with variable pitch?? Would…"
Mike Klinker replied to Harry Hubbert's discussion Variable pitch propellors on quadcopter"I worked on this project under Mark Cutler, I was his undergraduate hardware guy. If you have any specific questions about the hardware setup, let me know. I spent my summer working on that quad. Ultimately we found that your performance is going to…"
Harry Hubbert replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"Yeah im thinking of having the same sort of thing but im going to have two smaller arms for each rotor and they are going to be more vertical and rotated slightly so that when its moving forward it will produce a small amount of lift while still…"
Luke Olson replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"If you want to keep the airfoil arm shape it might be more efficient to have an "H" shape frame where the airfoil goes left to right coming from the center and then a rod goes from to back (on each side of the wing) for the motors (still a…"
Harry Hubbert replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"Yeah i was thinking that but it is going to have to carry weight, and that weight will have to be from the middle electonics case so they need to be strong, They have an aerofoil cross section aswell. but might re-think it and try think them up a…"
Luke Olson replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"The arms seem kind of wide, if they are wider than the need to be it can block airflow from the props and reduce efficiency. Is the clear middle area for the electronics and batteries? It looks very cool!"
Harry Hubbert replied to Harry Hubbert's discussion Heavy lift quadcopter/hexacopter"An update for the project, below are some pictures of the design so far, and before any of you go all "this isn't right" on me its just a rough plan trying to get the layout done and the general look i want it to have but any…"

- About Me:
- I am a current naval architecture student at the Australian Maritime college of tasmania, Australia. Studying to specialise in defence applications.
- Tell us a bit about your UAV interest
- I am extremely interested in quadcopters and some new applications for them. I am looking at creating a heavy lift quad-copter that can engage an extra 2 ducted fan jets when required to lift weight, to carry a automated submarine that myself and colleges have designed and built. I have access to 3D printers and all electronics, In real need of assistance with coding mainly.
