Higher timing = higher kV, so higher RPM, lower torque*. Motor temps will likely increase, and run time will probably decrease.
Lower timing = lower kV, lower RPM, higher torque*, lower motor temps, longer runtime.
*With torque, some sources say higher timing = higher torque, some say higher timing = lower torque and I'm not sure. I believe that higher timing = lower torque, as a higher kV motor has less torque than an equivalent size lower kV motor.
