Default Rock Force Build with some Cow Bell...

I was so intrigued by this rig that I just had to do it.

The idea of worm gear diffs made me take the leap.

Well, I picked it up at AB-C yesterday. First impression when I opened the box was good. Only disappointment is the wheel and tire selection. These will not be good for anything but bashing. They are a wheel with a real soft tire and no foams.

First thing I noticed is you better make sure you have gear grease, thread lock, etc. This kit does not supply these items. A good grease is very important being that wormgears are known to heat up with excessive running. I am using RC4WD's Monster Lube.

Instructions are very clear as Kyosho has always been good at.

So let's start with these axles... The gears are heavy metal...great tolerances...

The axles are set up pretty neat...the drive cup is enclosed in the axle case and then there is a dogbone that comes out to the stub axle...

These dogbones are massive...look at the compared to TLT's

Both axles are build...these things are heavy and bulletproof...

Now comes the tranny or should I say the motor mount with a spur gear. To explain this, with the wormgear, all reduction is in the axles. This eliminates torque twist and also gives you the best drag brake around.

My first plan was to throw in a 35t warrior...they actually recommend a 24T. I figured, what the heck...and through in a 7T Puller... :wow:

The chassis consists of the Tranny? and several plastic cross supports.

The driveshafts are an interesting design. They consist of two half shafts, a hex shaft and an aluminum sleeve. Great design.

Axles are on the chassis...

Shocks are a nice set up. The fronts are shorter than the back for better function. The come with aluminum caps and plastic bodies...they do offer an aluminum body upgrade. I am running 30 w Oil in them...

The place where they tell you to mount the ESC and RX is two cross bars...I attached a piece of lexan to make it easier to mount.

The wheels and tires had to go...

I got my Mayhem Dbl Phattys with Rock Crusher tires and Kreepys. These things are heavy will be just add to the planted feeling...
Problem is that the RF has larger axles so I had to get the drillpress out and open them up...

Findings...

The Puller is definitely the way to go. It gives you all the torque and still wheel spin. I may try a 4s to see if I can get some more top end speed.

I will definitely need a softer tire. Actually may give the OEM tires a try with some foam in them. They are pretty soft.

Waiting on the dig set up. We're having a Test'n Tune this Saturday so I will know better then.

Need to get another body for comps though... :-(

Nice posts. Very detailed.

What is your track width though with those wheels, has to be 11"+
