Me and my brother have build offs to see who can build the better model. and I decided that I will use gears to up the speed on an old design of mine.
here is the result.
Word of warning: do not use more than three gears to increase speed. This requires you to use the bigger wheels at the back creating more weight. As the increase in speed causes lower torque your model will fail to reach top speed.
Step 1: Body
follow as the images show
Step 2: Front Axle
the wheel is 2 wheels thick
Step 3: Back End
Step 4: Rear Axle
Step 5: Back End Assembly
Step 6: Insert Gears
Step 7: Finished
if you don't want a racer just extend the rear axle. and swap the gears and use larger wheels. this will provide more torque so it can be an offroad racer.
hope you enjoy and feel free to post mods such as the offroad mod.
and I hope to be posting the Automatic RBG.
