First, congratualulations to Brian Wolfe, the winner of the second round of the T3 Contest. Now it's time for Round 3.

This round's objective is to break the Stanford team's UAV altitude record of 7,142 feet by doing at least 24 circles with a 300ft climb and descent in each, as shown above. (This won't really beat his official record, because there won't be an official judge there. But you'll get bragging rights, at least).

The winner will have the highest cumulative altitude, but anyone who exceeds 7,142 feet will win a prize.

As usual, you must submit a KML track and video in the comments below. Evidence that fun was had is welcome (and may influence Gary's point assignment blackmagic equation), but is not required.

Deadline is Midnight PST on November 29th.

Wow Chris, 1 hour 24 with an Easystar, that's fantastic um er um, is 140m not at little high?? I think 120 and a bit meters is what's needed, KML would be good to see as well. I will sit on the fence for the minute as regards the altitude bust. If the area you were flying was 20m above your take off point then you would be ok!

Gary, as you know one of my attempts for the T3-2 round ended in a tree. Terrain where I live is quite hilly and full of 20-30m high trees. Therefore for me 40-50m agl is about the absolute lowest safe altitude for RC flying, if I stay whitin a circle of about 100m. Hence, I do not think I break any rules if I went to 140m agl, General aviation aircrafts must offcourse also add "extra" altitude to stay clear of ground/trees, (more then me).

If a very rapid pressure change would occur, the flight would be off by 10m worst case over 1.5h. 20-10m=10m is nearby tree.
Even if I fly in perfectly flat terrain, I am not leaving any model in such pattern below 40agl.

Well yes remaining clear of the highest object in the surrounds is ok, thats still 400' AGL from the top of that so thats all good.

But I will not look well on objects 100m high!! That means your not flying in a suitable location!!

Thanks Gary, then I just have to wait for some better weather. Winter is knocking on the doors around here.

Looks like a birthday cake.

Chris Bosak,

Nice, Chris. Very nice. That's a lot of LiPo you had on board. How much did it weigh?

Can I hold setup specs a mystery until the end of tournament?

Yes I think you can Chris, I'm back in Africa and am going upto the Berg later today, if I take off at 7000'.... No that really is cheating.

Hi,

seen that Chris does not have a simple up/down pattern but a "birthday cake" one (;P), would it be allowed a pattern with climbs in any direction?
