JJRC Q65 Make it crawl

I will try to make my JJRC Q65 almost as capable in terrain as my other 1:10 scale cars. After all it´s allmost exactly 1:10 scale in length and height but only 1:12 in width. What I have to do is uppgrade the motor to get torque and drivetrain to stand the torque plus find the right wheels that give grip and a wider stance, as the car is a bit too narrow and will roll over too easy. This video shows my first attempts, plus some of the small other modifications, of which the functional roll cage is the most important.
