I want to get into drifting. I would like to get a medium sized car around a 1/16 scale, but would consider a 1/10. Reason I want it smaller because I want to be able to do this in my basment. I have a Losi rally car brushed. Is there a micro drift gyro that will work with this car? Please reccomend a decent car to get into drifting. Any comments help, thanks.

Gyro's really make stuff less fun. Just wrap electrical tape around the tires and drift away. As for what 1/10 or 1/16 car you should get, it comes down to more information from you.
Do you want a car purely for drifting, or one that could rally or drive grip as well?
What is your budget?
Do you want a counter-steer setup?
Do you plan on upgrading later?
