Hi,
I am using and Arduino uno r4 for a rc car uni project, I have used a 6v servo attach to a 3d printed rack and pinion system for steering. However I want to make a fast accelerating rwd car and I was wondering what would be the best 6v dc motor for torque. My current dc motor just doesnt have the torque to move quickly any suggestions?
For some extra clarity of my setup I am sending the current motor thru a mini 3d printed diff and im using a simple mos driver module for the motor and servo is just wired into common 6v and ground with signal going to ardunio.
thanks,

From a Google search:
Fast RC cars use brushless systems including Traxxas VXL, Team Corally motors, and Hobbywing ESCs, deliver 50,000+ RPM power, and reach 80+ km/h speeds.
RC car performance multiplies with higher cell counts from 3S to 8S LiPo configurations providing 11.1V to 29.6V with 4x4 all-wheel drive systems.

A 6V 10,000 RPM motor is just not going to cut it.
All my RC carts are pretty slow with normal RC cart motors and NiMH cells.

PS Steering and diff sounds awesome. Have to look into that.

Thanks Jim, ill look into a 3s lipo system.
