I got a Micro Rs4.... Iz there a good 20 dolar electric 130 motor i can purchase prefalably black in color that iz faster than that motor in the title....

i do not know much about that stuf but i see a lot of 130 tamiya with diferent rpm range some 32000 some twice that....

i can shave weight and gain in speed with that motor 130 size and a motor with more power iz like the new stock motor in my micro rs4 box....

There iz a home run 78000 rpm black motor on ebay for 20 dolar....

iz that faster than the hpi....

space....

I used to have a micro rs4. I don't think tamiya motors are the best replacement. The best I've used was a graupner 300 speed 6V motor. Runs great and even better if you have a 7.2V battery pack. The downside though is that you have to purchase a different motor plate to accommodate the bigger motor. It's well worth it though. Do a google search and Good luck. Hope this helps.

I had a graupner 6 cel micro rs4 stock and 45t brushed....

Can any one here make a 130 motor all black and sensored with ceramic bearing carbon brush and match the 45t of this motor....

Actually the stock micro rs4 motors (part #1060) are 180 and not 130 motors. I believe that the number pertains to the axle length (180mm vs. 130mm).

Part #105506 looks just like the graupner 300 if I remember, they used to call them big block motors.

The popularity of the hpi micro rs4 was hugely based on the ability to use 1/10 scale electronics. So using these motors wouldn't pose too much of a problem if you're using an esc for 1/10 scale.
