On a hobby-grade electric RC the most common adjustments you'll probably be making are getting your drivetrain gear ratio (spur gear/pinion gear) set right and making adjustments to the slipper clutch.

That's all well and good but if you're new to hobby-grade RCs it may also sound completely foreign. So, first things first. Let's get back to the basics and describe the key elements we're talking about here:

• Drivetrain
• Spur Gear
• Pinion Gear
• Slipper Clutch

Now back to those common adjustments.

The gear ratio setup helps determine things like speed and power. Some gear setups provide your RC with a lot of get-up-and-go right off the line while others may have you starting off more slowly but give your RC more top end speed. Changing your gear ratio setup is most often a bit of trial and error, mixing and matching different spur gears with different sizes of pinion gears. Often RCs will come with a selection of different size gears so you can choose the setup that works best for you.

If your RC is equipped with a slipper clutch you may find yourself making adjustments to suit the type of track or terrain. On a short track you might want to tighten the slipper to give a little more punch around the corners and off the line. You may also want to try tightening the slipper clutch if you're having trouble pulling wheelies with your RC.

Loosening the slipper slightly on longer tracks can help you maintain consistency on the long sweeping turns. But on any type of track, long or short, if you have a lot of jumps you want to loosen the slipper a bit because it can put too much stress on the drivetrain during landings if it's too tight. As with the gear ratio setup, it can take some trial and error to find the balance for your slipper clutch -- and you may want to tighten or loosen it for different driving conditions and for the experience of knowing first hand how different settings affect the performance of your RC.
