XC Triker, The red gloves do help when you have four or six aircraft in a formation the other pilots can see the leaders hands when you are on the ground or in the air.
Thank XC, I had only just turned to take the photo, and I wasn't even looking or viewing through the lens at the time. After seeing the shot once on the ground, I thought I should do that more often...
You can draw a rectangle on ground like on competition 100x15 meters. Then you can take off from this box and land also there. Like on aircraft carrier, if you go out of the box you will swim in the sea :)
