There's a lot of interest in R/C planes on here, what about cars/trucks? I race locally everything electric. Here are some of my cars:
1/10th scale electric on road:
Team Associated TC4
1/18th scale electric off road:
Duratrax Mini Quake - brushless motor and lithium batteries; I don't know how fast it goes, I'm too scared to pull the trigger all the way back!
King of the old school 2WD buggies:
1987 Traxxas Bullet
In the winter, it's too cold to race outside, so I race 1/28th scale Mini Z's indoors:
I've got a lot more, a purpose built rally car, a stadium truck, a few shelf queens, and more stuff than I really ever should have.
