Upgrading a Lamborghini Aventador ride on car

This car was a birthday present for my son, a sleek styling and powerful ride on car, which can be manually or wirelessly operated. Although running on a single 6V lead-acid battery, the motor is quite strong and enough to carry an one-year-old baby at 3 km/h for over one hour.  The wireless controller is a nice feature, which allows parents to directly control the car have fun with the baby, however the controller only has a limited function: forward/backward and left/right at full speed. Since the motor is switched on and off by a mechanical relay rather than MOSFET transistors, the speed of the car is fixed at a maximum level and that is uncomfortable for the baby when starting up.

Fixing a brushless ESC

I have recently received a RC car from Hobbyking, the 1/10 Quanum Skull Crusher 2WD Brushless Monster Truck, very powerful, very fast and it actually roars like a monster. Comes with a 35A (190A burst) brushless ESC and a 3650 size 2700KV brushless inrunner motor, these parts are getting very hot when running (and the ESC needs an extra cooling fan).
