Chris, I think contestants can go below 100' if they dare, that could be another 50' per turn!

The blackmagic last month was in the hat.

Interesting Contest Some or the other day I will participate ! for Sure.

Gary, fair enough. Consider 100ft a recommendation, not a rule. But 400ft is a rule!

Comment by Vassilis on October 28, 2009 at 6:18pm

Gary, Chris: why put the limitation of a single ascent/descent per circle? If for example my model can climb up and down twice in a single circle will that be acceptable (while not exceeding the 400ft limit)?

If a single ascent and descent is allowed in a circle then that will either put very strict limitations on the climb rate or if the target altitude (400 ft) is reached before the circle is done then we will have to hold altitude until the circle is completed. If this is the requirement then it will not be fair to compare our results with Stanford team since they did not have that limitation (to my understanding anyway).

I am fine either way, I would just like to know before I give it a try, the good days in this part of the world are very limited so I do not think I will have more than one attempt at it.

Circles are just round trips, right? We're not going to be judged on the beauty of our loops are we? I'm afraid mine might be pretty ugly.

Hi,

is it required to be circles, or is it enough to fly between two wp, one bottom and one on top?
In other word, is it possible to program a different fly path?
This way we can see wich path is more efficient with wich model, because I guess this is not the same as to climb straight one time.

Regards.

I don't think it has to be circles, I have a feeling that has to be the best way, but could be wrong, and yes if you can get up and down again within one circle then thats fine, just as long as the radius is within VLOS which for our purposes I think we can set at a radius of 300m any more is getting far.

3D Robotics Comment by Chris Anderson on October 29, 2009 at 4:35pm

Yes, it doesn't have to be circles, pretty other otherwise. We just want you to stay under 400ft and within VLOS.

My results from the last weekend:
Easystar lipo 3S 4400mAh wiht FLEXIPILOT,
33 climbs about 91m each
5044s total 1h24m4s
4694s in pattern
Cumulative groundtrip 38.190km
3118m cumulative climb

kml and video in preparation.

Plots in order are:
1. temperature (IMU and baro)
2. groundtrip
3. baro altitude
