Is the Kraton 6S worth it over the 4S version?

If you already own 6S packs and a charger, the 6S BLX gives you the 60+ MPH headroom and stronger Spektrum electronics. The 4S truck costs less to power and is gentler on parts, so pick it if you want lower running costs.

What do I need to buy to run it?

Two 2S or two 3S LiPo packs with EC5 or IC5 connectors, a compatible charger, and four AA batteries for the transmitter. Nothing else is required out of the box.

How fast is it really?

Arrma rates it at 60+ MPH with a 6S LiPo and the included optional speed pinion, in optimum conditions. On the stock gearing and 4S it is noticeably slower.

Can I run it in wet or muddy conditions?

The receiver box is waterproof, but that does not make the whole truck submersible. Wet running is fine for splashes and damp grass; clean and dry it afterward and check bearings.

Is it too much truck for a beginner?

It is adult, hobby-grade equipment with 6S power and a 10.67 lb curb weight. A smaller 1/10 truck is a safer first step; this one suits drivers with some RC experience.

The best new price seen is $599.99 at Iron City RC Hobbies as of November 4, 2026, with three stores listing it new. Compare those listings before buying, since Arrma kits often drop around holiday sales.

What reviewers say

Owners treat the Kraton 6S as a durable, well-supported basher that takes jumps and rough ground in stride. Most complaints center on setup costs and the parts that wear or break under hard 6S use.

Pros

Tough drivetrain that holds up to repeated jumps
Strong parts availability and aftermarket support
Straightforward handling for a truck this size

Cons

Battery and charger costs add up quickly
Some plastic and driveline parts wear under hard 6S running
Heavy enough to need a large running area
