MRC Baja King Ads

The MRC Baja King, released in 1993, was the stadium truck version of Model Rectifier Corporation's "World Scale" line. Designed as a racing model the kit came equipped with bearing in both the transmission and wheels, a low mounted stadium truck body, and no electronics.

Is a World Scale a 1/4 scale? I've never heard of this before.

I don't think they were that big, 1/7 ish maybe? From memory, MRC never listed the scale as the buggies and trucks were similar in size. I remember them from RCCA, but never actually saw one in person. I found this photo with a humpback battery (looks to be an 8 cell ) in shot for size reference.

They were close to 8th scale.

Short answer:

1/8th scale

Long answer:

The Nitro Thunder King was advertised as 1/8th scale and shared the same 14 inch wheelbase as the electric Thunder King and Baja King "World Scale" trucks... which, like 1911Colt mentioned, never had a fractional scale listed.

The math on the wheelbase works out to 1/8th scale too.

A 1/7th scale truck would have a 16 inch wheelbase, very close to the 15.87 wheelbase of the Desert Thunder buggy, and likely where the connection to 1/7th scale originated.

I love the MRC World Scale items.

I always thought they were 1/7 scale as well.

I have a really nice Thunder KIng runner and a NIB Thunder King and a NIB Desert Thunder.

The previous owner of the Thunder King I have that is NIB came with metal heat treated RC4WD gears. Which was part #Z-G0048

Does anyone know what size tires the Thunder KIng takes? The one I have are deflated and need to be replaced.

At the time I remember it being a new oddball scale they were trying to have catch on that never did. My favorite was the Baja King due to never seeing a stadium truck that big before. It just seemed so awesome to me. I mean it still does.

I don't know about replacement tires but I think a lot of models these days have comparably sized tire/wheel combos if you don't mind changing both. I once came across a website where someone hopped up a Thunder KIng using all modern truggy parts I believe they were which conceivably converted it into one. It looked terrible to me, but showed what could be done with them.

A few folks, some on here, have swapped tires from other manufacturers...

The tires are Imex Dirt Dawgs and they are a perfect fit for the stock wheels, as are most of the E/T-Maxx sized tires.

Or, if you don't already have them... MRC's part numbers to help you track down some original tires:

Thunder King Tires (pair) P/N 9627001
Desert Thunder Front Tires (pair) P/N 962002
Desert Thunder Rear Tires (pair) P/N 962003
Baja King Front Tires (pair) P/N 962004
Baja King Rear Tires (pair) P/N 962005
