Yes, that drift was strong, especially when the crowd was large. Human induced thermals!

If you played your cards right, you could actually ride the thermals to keep the plane up in the air up longer, especially with those hot lights up top.

The net lowering and raising seemed to cause drifts towards it, as well.

[coachchuckaahs]

Not sure how to "play cards right" in this case. Air was going up over people, across the ceiling, then down near nets. This circulation moves a plane up top toward the nets, and more importantly, toward the downward motion. Ideally you would launch in neutral, or even in the downdraft, to absorb the launch torque. You would then want to drift to the updraft for the letdown, so the updraft helps your letdown last longer. However, since the drift is a function of the updraft, it is always AWAY from the updraft. The upward moving air must go somewhere! Therefore, I don't know how you could get your letdown centered on the updraft.

On my first flight, it seemed when the plane was in the center, the plane kept getting pushed up on the descent. Was just odd. If it was just me disregard my comments.

It is quite possible that the air currents were different. Since we flew early in the day, and you few late. If there were localized thermals, it is possible you flew in and out and could take advantage. In our case there was a strong drift across at the top, but not at mid levels. But, still, if there is an updraft, there will be a top-level drift away from the updraft, the air needs to go somewhere. If there are local circulations ( from local heat sources, like the lights), one could catch the slightly lower inward rushing air and get drawn back into the local thermal. If these were R/C or otherwise controlled, one would purposely fly it into any rising air (say, over the crowd).

when we flew, it seems there is strong air current on top, I would say maybe above 20ft. after that, it seems to be better

I was flying 3:20 in a 28' ceiling. Added 25 winds more than practice for a 'safe' first flight. In last session there were a lot of people watching and my plane went so high it hit the curtains a couple of times before hitting the wall, and crashing to the floor. Second flight I again flew on the opposite side of the room as the nets (where the observers were sitting) and again saw abnormal climb rate (during one part of a particular circle the plane jumped about 5' feet in height in a few seconds. Then while cruising at the top it moved all the way across the room (my circle size is approximately one of the quadrants of the room) towards the nets and at about 2:50 and ~20' the prop clipped the net. Ended with a 3:13 time and 10th place. Considering the circumstances it could've been worse, but I am still a bit disappointed in my time.

Shoutout to Brian Turnbull and Dan Simko for providing advice and helping us improve significantly in the past few weeks!

Scott,

Great job in WS! Your airplane probably had 4:20 in it except for the bad luck with the curtain.

Great Job to everyone! I was wondering if everyone in the top 10 could post a picture of their plane onto 2019 best of nationals page. Next year's specs will be different and hopefully, there will be an interesting bonus so the plane will have a different design.
