super slick motor in a bit
Posted: Tue Aug 10, 2004 2:19 pm
I put a purple top super slick motor in my bit. It's faster. The purple top motors are rated at 27000 but it is definately faster than a perfection 3.8 or 4.2, witch are both rated at higher rpm's.
Only one catch though. I'm using it in a car that is fet modded and has a kokam 3.7 volt 135mah li-poly battery running it. I'm pretty sure the motors almost have to use a pcb with fets. I doubt a stock bit pcb would even turn the motor over. Also, the super slicks use 2.4volts (I think). A single cell bit only has 1.2 volts.
I'm going to mod another car for dual cell nicads and fets to see how that runs. Will post on that if anyone's interested.
I used the superslick's motor because I was killing regular bit motors too quickly with that li-poly battery and fet combination. I thought the super slick motors would be a good idea because they are still small enough to fit between the rear wheels and seem more sturdy than the delicate bit motors. It's also not a whole lot heavier than a bit motor and I can still fit the NSX body on. Well it's worked so far. The motor hasn't burnt out or slowed down. I did have to dremmel out some space in the motor compartment and remove the heat sink. I'm holding it in place with metal wire.
Speed checks soon. A rear whell flew off. I had done a wheel mod and the superglue didn't hold. I put some apoxy on it and I'm going to give it a day or two get a good strong bond before running it again.
Some other people need to try this. I use it with a 2-speed bit pcb and it still pops wheelies unboosted/1st gear.
