Crawler Electronics & Tires
Motor & ESC
If you buy a kit, clearly you will need to also buy electronics. But - even if you get a few of the RTRs noted elsewhere, you will probably want to upgrade to one of these cutting-edge brushless setups anyway. The amount of power you can get from a small package is really surprising anymore.
Tires
Traction is king in rc crawling. Without the right set of tires, you are not going anywhere. Good news - one of my favorite things to do is try new tires! Below are the crawler tires that I tested and confirm perform well in my area. They are a great starting spot for anyone, but know that you may want to keep testing as all terrains are not made the same.
Tire Inserts
Foams have been the standard for crawler tires for years - but the invention of inserts has really pushed them to the side now. There are MANY individuals that create GREAT products that out perform standard foams. Even if you are not super-serious about crawling a set of these is well worth it!
Wheels
The world of RC crawler wheels is HUGE. Soo many companies, soo many designs. It is enough to make your head spin. This list includes wheels I have personally used and tested and can fully recommend.
Servos
You never really appreciate what a strong servo will do - until you get to use one in a crawler! I have personally tested A LOT of servos. From bottom-dollar to super-premium. These are the ones I recommend.
