I set the limbo rig up today at the field.

I have two 15" metal stakes that pound into the ground.
The PVC poles fit perfect over the stakes.
the poles stand straight but will bend easy if hit with a plane.
Crepe paper is 80' on a roll, just the width of our runway.
Paper was 8' - 9' high in the center of the runway.

It sounded like it would be easy to fly this but after seeing it set up, at my skill level, this looks pretty tough.
better pilots could have it lower.

I would give a penalty for cutting the ribbon!
to much work to replace it.
Score points for flying under the ribbon.
How many times can you fly under it in 2 minutes?

Sorry forgot camera.
