Last year we drilled two holes opposite eachother in the top of the PVC Tube (probably not legal
) and stretched a piece of surgical tubing through the tube. This held the flag in very well and would also allow for the addition of a second flag if needed. Face it, when the flags stay in, they really do the job they are designed for. Others have stated and I agree, next year and beyond we will probably not have a game piece that can get stuck on them. Lights use power and can break. Changing out bumpers, forget it. Our team was in que, next up, when the first call for quing for our next round was heard. With only a few matches between matches the kids had all they could do to run the check list and swap out the batteries. No way could they have changed out the bumpers. I agree with another post that talked about a bolt on flag with a spring on bottom of the shaft. Why not offer flags that have poles 2', 3', 4', 5' long or what ever to make sure that the flag is above the max height of the robot (starting configuration) giving teams the ability to design a robot where the flag could be mounted at several different places on their robot and still have the flag above the robot? It seems like this would give the teams the greatest flexibility in flag location and would not be a constriction on robot design and allow for easy identification during matches.
