Default Re: Monster Problem

Originally posted by jedi
After reading all the rave reviews about the monster, I bought two of them with high expectations. I usually run tamiya 23t stock motors and expected the monster to be slightly faster. I ran one of my monsters and was sorely disappointed. This thing is sooooo slow. I am running an Evo3 with rubber tires in a concrete outdoor track with a 150 foot straight. The track is rather open and flowing. Tried to tune the Monster by aligning the brush hoods. Tried changing the springs to purple on both sides. Tried using Tribo. Tried all final drive ratios between 6.7:1 to 7.8:1. Nothing seems to work. Now I dont want to use my second still new in box monster for fear that it will be just as slow. Any help would be greatly appreciated. Thanks.

That is a VERY large Track. If you find yourself hardly slowing down in the corners 6.7 may NOT be tall enough yet. Also the Purple springs will drasticly cut down the Power/Torque. For a large flowing Track, I would use the Red/Green springs. Make sure that the Arm is not shimmed too tight with a minimum of .008

Another thing, Jedi, which brushes are you using in your Monster? If you have a regular Monster & are using it's original brushes, then that could be your problem. The brushes in pretty much all "untuned" motors are cheap copper/graphite brushes that really aren't very good for power. If that is what you have, then I'd suggest you try Trinity's 4505 brushes, I think you'll notice a significant improvement(although I'm not sure if it'll ever be quite as fast as a 23 turn motor like that Tamiya)....
