Keep In Mind
We all know that now is the age of brushless powers. So, having a brushless setup is a plus. If you own a brushed motor you can continue with that, but you have the option to replace it with brushless. When you decide to go brushless in place of your brushed motor, you just can’t order any motor. You first have to know whether your model is compatible with it or not. If your model is incompatible you have to put extra money into some extra parts like Esc device, battery power, etc. You have to research to make sure what will work for your model to switch from brushed to brushless.
In our list, we have kept both brushed and brushless options. If you do not want to experiment or take risks for your brushed motor to exchange with a brushless one, you can simply buy a brushed motor. And those who own the brushless model, simply choose a brushless motor from our two choices. However, in this case, we recommend Spectrum Firma’s 84a brushless motor combo, to get the beast power.
Takeaway
Whether you own a brushed motor or brushless motor of your Arrma Granite, for heavy bashing if the motor is broken, you have the solution for an upgrade. From our list of three, you will get both brushed and brushless choices. Generally, brushless motors are more expensive with more strength than brushed ones.
