It seems like I have to give the car way more throttle to get the tires to start turning than what I remember. My transmitter is showing 20% throttle before the tires start spinning even sitting on a stand. Does this seem right? Once the tires start spinning it's like the drivetrain is out of balance as tires fluctuate in speed. What should I start looking at? Thanks for any help.
