One model hit the scoreboard wires, and was lucky to escape. A few other flights had light touches on the bottom of the main beam. These flights are mostly safe. All other flights were "no touch."

The beams are 106' high in the middle and probably 100' high at the 250' boundary. In essence, the open air space is 124' x 250' x 100' high. If you fly in this space, you are free from obstacles. This is a lot of airspace.

The main obstacle is the scoreboard and the wires from which it hangs. You won't be able to steer successfully on your first try. With practice, you eventually get better. This year, I had about five successful steers and one unsuccessful.

All the others came straight down. Flying in a restricted airspace 62' wide that's bordered by two of the beams, these flights were nevertheless uneventful. Pick the right moments when the East-West drift is low to challenge the ceiling. You also cannot challenge the top with every model. I don't fly my EZB all the way to the top because it cruises for a very long time. At the top, it may be in danger for up to 15 minutes, whereas the LPP might only be in danger for 5 minutes.

Of course, it would be even better if the scoreboard were absent, but that's history. If you fly a smart game, you can minimize the chance of a hang up. Study the conditions, get your launch torque right, and you can fly long and safe.
