Hey Swingnamiss...

Ya buddy, you need two servos. Keep them the same brand, but different models. There are different kinds at different price ranges, ones with plastic gears, ones with metal/titanium gears and digital ones. Use two different kinds, same make, but different torques and response speeds. Talk to the store you're buying it from and ask them for their opinion. It depends on what's available in your local market as well. JR9000 range is considered amongst some of the best, Futaba digitals also up there. Hi-techs are good as well. Everyone has an opinion and personal choice about almost everything related to this sport mate. Also, keep in mind that some servo arms don't fit all servos. So make sure you get servo arms made for the servos you're running. And make sure the screw that goes through the servo arms fits the hole...

Your LHS (local hobby store) should be more than happy to point you in the right direction and explain all the reasons for the different requirements for the servos on you car. Satisfied customers tend to return with more business.

And as far as your choice in car...you'll love it
