The Traxxas TRX4 has recently become a very popular crawler. The fan community is getting bigger and bigger and there are also more and more questions about how to implement what. This page should be a little guide for the beginner.

Like all things, not everything about the TRX4 is perfect. Some components are certainly in need of improvement, others are quite prone to failure. The steering servo from Traxxas is certainly worth mentioning here.

Important notice:
The steering servos of the type 2075/2075X of the company Traxxas must be regarded simply as extremely failure-prone and inferior, that Traxxas is informed about this problem since very long time, it apparently does not change, makes the whole not really better. If you buy a TRX-4 ask your dealer directly for a different steering servo. Some dealers will even tell you about it, or offer sets with a different steering servo. Please read also in the section engine and electrics!

Meanwhile, there is probably a new production of the steering servos should last much longer!

Current Traxxas bodies based on the TRX4 chassis. The bodies are still available in different colors or in clear to paint yourself.
