The first thing you should look in to upgrading on the Ground Pounder is the motor :
Really I find the top speed pretty good but I feel the truck needs more torque for driving in grass and driving off road .
My recommendation is a 550 motor with 19-22 turns here are a few examples :
Redcat Racing Part # 28446 sells for about $16.99
Traxxas Titan (21T) Part # 3975 sells for about $21.49
Thunder Tiger part # PD9221 sells for about $27.99
My second upgrade I recommend is to upgrade pinion and spur gear .
Part # bs801-014 is a 43 tooth mod 1 spur gear made from a composite plastic that can replace the stock spur .
About $10.00
Part # MPO-017 is a steel version of the BS801-014
About $14.00
Now you will need at least 1 pinion that has a Module 1 tooth profile . If you are using a motor with a 1/8th inch shaft " like the ones listed above " here are a few options.Pinion Gear, 9T/12T x 3mm, Mod 1 part # ECX232028
about $13.00 for a pair
OFNA 3mm Bore Mod 1 Pinion Gear about $12.00 each
11 tooth = Part # 21316
12 tooth = Part # 21314
13 tooth = Part # 21315
14 tooth = Part # 21306
15 tooth = Part # 21311
16 tooth = Part # 21312
Do these motor swaps mount to the stock plate and position on the frame?
ReplyDeleteYes they bolt right up only real external difference vs the stock motor is their overall length is longer .
DeleteWill it be ok use stock ground pounder motor with mod1 spur and say 15-19 pinion I ordered a set comes with 15-19t mod 1 pinions
ReplyDeleteI don't recommend using a 15 or 19 tooth pinion in a mod 1 upgrade it. Now I'm not saying it wont work but that's some tall gearing and it will probably over heat the motor unless operated for very short periods of time or on a very smooth hard surface like asphalt or concrete . With the stock motor I would recommend not using over a 12 tooth and believe most will be happiest with a 9 tooth for driving in a off road environment.
