Definition: To upgrade or improve either the performance or parts is to hop-up your RC vehicle. It is usually only possible to add substantial hop-ups to hobby-grade RC vehicles. Installing a better tire, motor, or new body are common hop-ups.
Many RC manufacturers produce upgrade kits for some of their RC vehicles that include some of the most popular hop-up options.
Also Known As: upgrade
Alternate Spellings: hopup

Installing a faster, more powerful motor is a typical hop-up for professional RC race cars. Upgrade kits for XMODS typically include hop-ups such as alternate style body parts or more stylish wheels.
