Rim size is 3.2 inch and uses a 12mm hex . Basically Common rims that fit the E-Maxx and T-Maxx will fit if you use 14mm or 17mm wheel  hex's there are lots of options . Most recommend the 3/4 inch stable maxx offset for additional tire clearance.

Pinion and spur Pitch is standard 48 pitch and not mod.6 as stated on the stock replacement pinion.

The smallest pinion that can be use with the stock spur gear and without altering the stock adjustment channel is a 17 tooth pinion.

What pitch Is the Redcat Racing Ground Pounder Pinion and spur.

So what did I learn to day .

That Redcat Racing's part's Number BS701-019 is miss labeled . There website states : Pinion Gear 23T (.6 Mod), M3 Screw ~ . This is partially in correct it is a 23 tooth pinion but it not mod .6 / metric 48 pitch it is in fact imperial 48 pitch go figure . So don't waste your money if your looking to gear your Ground Pounder down  on .6 modual pinions as you will burn through a spur in no time.





P.S. if your new to the hobby the best deals on 48 pitch pinion gears is the Robinson Racing Six pack starter set Part # 1050 / 1055 .   
Part #1050 comes with a 16T 18T 20T 22T 24T 26T steel pinions Part # 1055 comes with 15T 17T 19T 21T 23T 25T steel pinion . There a heck of a deal at as each set normally sels for less than $16.00 .

Well I been playing with the Ground Pounder .


I decided early on I wanted more grunt out of the Ground Pounder. So I Swapped the 23 tooth pinion for a 19 tooth pinion and to be honest I feel it needs more torque still If its going to replace the Clodbuster for my purposes .

I played a little to day and shot a little video sadly I forgot to change the camera settings so not the best quality but hey its a running video.


I will soon be adding to the broken parts list its only a matter of time.

New Toy is on its way " Redcat Racing Ground Pounder "

Yup I did it I placed a order for a Ground Pounder I needed something to take care of my Snow driving fix and for the money I cant complain about the durability and performance I have seen from my step-dads truck so expect to see a lot of stuff when it arrives.

Current plans for the future include :




I plan to experiment  with the stock motor and several brushed aftermarket motors but eventually a brushless system will find its way in .

Since the ESC is rated as 3s lipo capable I'm thinking a 20 or 19 turn brushed 550 motor powered with a 3s lipo should be the ultimate budget system for the Ground Pounder just saying . 




Steel spur gear upgrade if necessary but the plastic version will probably do . BS801-014  MPO-017
  






Home made axle braces " Outlaw Hobby makes  makes some killer looking braces but $79.99 a pair is a

little rich for my blood "







Replacing the  shocks are on my to do list mainly because the stock spring diameter doesn't leave a lot of
options for replacements and replacing them also means I could install longer shocks with more travel.
