I'm a bigtime Traxxas RC Truck user, and I frequent their page and forums often. I also visit a really popular RC store for info and supplies. There are TONS of Traxxas users, since they are one of the industry leaders. I think many could benefit from such logos.

Main site: http://www.traxxas.com

Models that are popular:
Summit
Revo
TMaxx
Emaxx
StampedeVXL
RustlerVXL
JatoVXL

The online superstore that is used the most is
Tower Hobbies: http://www.towerhobbies.com

I don't have any real design preferences, just as long as they look good! Anything you guys make will look better then my screen shot images! Tower Hobbies is particularly hard because they really don't have a "logo" per se. It's usually just their name as shown in the upper left corner of their site.

Thanks!
