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.

I will stay aloof in these matters. A good story with peril used to go down well back in the day.

Exactly Robert, I suspect that case B is correct.

Flying the cube could mean flying all edges.

But, I think (and sincerely hope) they mean all corners.

I'm an engineer, we like to have these things spelled out.

Also, truly great interview with Chris, very informative regarding current and future activities and directions.

Chris has a real vested interest here, he is probably by default going to have to be one our main advocates with the FAA and all the half baked politicians crawling out of the woodwork who would primarily just like to see it all go away.

It is going to be really sad if the nation with by far the greatest interest interest in these things turn out to be the country with the most restrictive and destructive laws regarding them

Bonus points for winch use! LOL  (I'm not joking either).

Have you received payments from 3DRobotics or those associated with them? The reason I ask is that your topic of this thread comes in 23 minutes into a 27 minute interview, with the first part being a plug for 3DRobotics products. It's quite misleading.

25 years ago when I was crashing gas monoplanes on almost a daily basis  I knew of 3 pilots that could probably do it in manual with a gas air plane one guy was from London the other was from the States  and another guy from London with a gas  helicopter without a gyro They could bring their air plane down and sit on it's tail The guys in the " I have a Dream "video  Eagle posted a few days back  could probably do it as well. There is a lot of skilled  RC pilots out there  Following this web site there is a lot of really skilled Quad pilots that could do it    For the vertical legs they could  climb straight up tail slide down they would need some form of telemetry for altitude maby  tethered helium balloons at the 4  corners with markers at 20 and 50 m? Exciting stuff ! When the good pilots come to the field I just pack up my stuff and watch! You guys have a Great day!

Man, I would be interested but I'm not part of a club and any place 500m from a road is in the middle of the woods. Too bad!

Great to see the T3 contest back.  If you're using the arducopter code I think you'll have some problems because there's a bug in the navigation where it ignores altitude component when deciding whether to consider that waypoint complete.  I'm sure it's a very small issue somewhere so if someone finds it they may want to post it so multiple people don't waste time fixing the same bug and can focus on other parts that might make the cube better.

I think 1 minute at the corners is a bit excessive and makes the competition a lot about flight time.  How about 15 seconds?

Another bit of advice for people is that compass accuracy is very important if you want to make the lines straight.  So make sure you're not suffering from compass interference too much.

@J no I have not received any payments from 3DR or DIYD I am sorry to have misled you. Its a chat with Chris A so its bound to be 3DR centric.

Comment by Kabir on February 22, 2013 at 11:01pm

@Randy +1

1 minute is rather a bit too much.... As it is, its not easy and on top of that if it has to be an endurance run too...
