That's a problem with all clods. It's because the motors are separate, so when one is easier to turn, the power will go to that one and leave the other dead. Now if we could just adapt some nitro buggy brakes to the axles to put a load on the easily turned axle when they start to transfer power... Destroyer |

Make sure they are wired in series, that was juice has to go through one to get to the other... then the front may spin out while the rear is stopped, but it is at least trying to move with just as much voltage. I actually really like how it works now that I got used to it. On hill climbs I can get the front to REALLY dig in while the rear just pushes softly. Almost like havin separate front and rear drive. Oh yeah, and my 12x1 motors have PLENTY of torque  |

Another thing that will help on stalling is gearing or motor turns. You should notice that when one motor stalls, if you blip the throttle it will come alive and beging working just fine. There is a certain RPM/Torque range on a motor that gives it, its max. power and efficientcy. Once you hit this you can eliminate the stall. Each motor is different though. For example: Last week one of our buddies was running his clod with the very same motors that I run. His stalled a lot more than mine. The only difference is that he was running I think a 14 tooth pinion and I a 9. What this allowed the motor to do is wind up into its higher RPM/Torque range (the sweet spot). Always run your motors in that sweet spot and you'll reduce heat build up, the stall, and prevent unecissary wear. You'll also increase run time. So the trick is low gearing and high turn motors. A soft silver brush with a heavy spring on the postive pole helps a lot too. I'm not saying that you'll never stall, but it will be very rare. I run 55x1 motors, 9 tooth pinions with 3300 packs and 1 pack runs 2 hours and 20 minutes as of last weeks meet. Hope this helps  |
