Its been a while so lets try again. Had a hangout with Chris and we briefly spoke about the next T3 round. Chris will work on a top prize ;-)

The mission is simple, get airborne climb to 20m 

Fly a cube with 50m sides, pausing for one minute at each corner, so your flight time cannot be anything less than 8 minutes..... Bonus points if you can stay longer at each corner....

The neatest cube KML wins.

If you can do this with a 3D aircraft I feel you would have a very strong chance of winning!

I will close the competition on April the 14th. I will be looking at where you are flying very closely. Please don't try this in public places or within 500m of any building / road.

Richard, you have a good looking cube there, I'm gonna have to go do a better one now, mine is subpar! 

Here is my latest attempt. I only flew each vertical once, total time about 13 minutes. Finish cell voltage was 3.7 per cell. I have a 3s 5Ah pack. My verticals are a little snakey, not sure why. I am unsure what heading the quad picks during my climbs and descents, it seems random, or simply not a heading hold and drifts. I have found that if I put a heading into the "yaw angle" nothing happens. 

How am I supposed to officially submit?

OK, flew with my camera mounted on top of the Quad.  Not the best of cubes, but fun to watch.  The flight was completely automated from take off to RTL landing.  Just missed the launch pad on return.

Also tried to fly with 2 - 4S 5000mAh batteries, but could not get ALT HOLD to work.  zAccel was messed up.  I'm guessing some kind of harmonic thing.  I can do ALT HOLD perfect with one battery.  Go figure.  I flew in stabilize mode for almost 22 minutes.

    Great work!  Nice to see the video.

    Re Alt-Hold, I've heard that from one other person recently (although they were using an APM1).  2.9.1b has a wider acceptable range of accelerometer's 3m/s vs 1m/s in 2.9.1.  This plus reducing the INAV_TC_Z from 7 to 5 will likely make it more reliable.  There's a slight downside to having the TC at 5 which is that bad barometer behaviour can also appear.  On  my copter this means it does a little dip after flattening out after a highspeed forward flight.  Most people probably won't notice the difference but if you do you can always increase the TC back up to 6 or 7.

Richard: Fantastic video! Tweeting...

Excellent work from everybody with the guts to give it a go. Still very surprised that no other AP has entered. T3 was never APM only. Once again though, well done!

We've still got a couple weeks right?  Still hoping to get a tradheli entry.  Gonna be tight but my new big heli is almost ready...

What about YS-XS or whatever it's called?  

MK should do it I think?  WK-M of course, does it have enough waypoints?

Of DJI Ace One for Helis at $11,000!

Well perhaps this round will push what can happen with controllers a little. The point of competitions really.

Flying a multi around bores me to tears. Lets get them working!

There are other pilots with autopilot that are ready to compete but what is the prize?

Comment by Rob_Lefebvre on April 4, 2013 at 2:07pm

Gary, I agree.  I think we've got the basic flight stuff down.  I did a bunch of manual stab flights with my 450 heli on the weekend, but that got kinda boring so I started hot-dogging it until I hit a light pole...  I find it more fun to push my limits on what I can do in the auto modes, which was one of the main reasons I did this.  To prove it to myself.  (But I would graciously accept a prize! :D )

What is the price to unlock the waypoint functionality of ZeroUAV?  Just curious.

And what's the situation with WK-M.  It has some ability right, and at what price?

What happened to AeroQuad navigation?

How come no MK entries?
