So you like the pretty eyes bit.
To loosen up before the race:
I wack people with my antenna on my way up the stand and pretend i'm a noob that deosn't know better. Works best on the non-regular racers of course.
Sing show tunes.
Line-up backwards on the grid, then drive away when a marshal reaches for my car (an E thing).
Yell out "less than five" at random intervals.
spin around three times before picking a spot on the drivers stand.
say something random and stupid to the driver on each side of me before every race. IE: " I have a cat named molly."
Do at least 1 stupid thing during the warm up before the race. Doughnuts, run over the marshals foot (slowly), drive backwards down pit lane (if empty), hack a backmarker and say "there, needed that out of my system."
Bring an extra Traxxas radio up the stand with you. Throw it on the track, and point to the nearest person without a radio in there hands.
have fun, stress less.
