Type of Motor For Arrma Limitless
Before diving in too deep and discussing the type of motor that suits an Arrma Limitless we must first talk about the different types of motor available. You see, there are two types of motor available in the market.
One is brushed and the other one is brushless. But what’s best suited for Arrma Limitless?
Brushed Motors
On one side we have the brushed motors. Now, these are known to be quite affordable. But they don’t produce quite a lot of power. So, the question is will it be able to support a high-power Rc car such as the Arrma Limitless?
Well, the answer is yes. If you do find a compatible brushed motor it will work for a few days on the Rc car. However, they won’t be there in the long run. You see, the Rc car requires so much power that it will simply wear out.
In the long run, brushed motors won’t be an ideal option.
Brushless motors
On the other hand, the brushless motor might seem like a hefty investment. But trust us, it will be great in the long run. It can support the high power that the Arrma Limitless requires.
It also requires less maintenance. This is because there are no brushes present that you might have to clean.

Spektrum Firma Brushless Motor
First things first we have the one and only Spektrum Firma Brushless Motor. Now, this one is the number one choice if you have an Arrma Limitless RC car. But why is it the best?
Well, the fundamental reason has to be its 6.5 mm gold-plated connectors. Now, gold is an excellent resistor to oxidation.
Meaning that if your motor is ever exposed to any corrosive environment the gold plate will be able to provide protection. This way, the motor won’t get damaged and it will be safe from any corrosion.
Apart from this, it is super-efficient. So, the motor won’t waste any power, rather it will use its power in a more calculative way. Thus, damage to the environment will be less.
On top of these, the motor is made out of alloy steel. This makes the surface resistant to corrosion and renders it to be hard and tough. Thus, it can handle the power needed to support an Arrma Limitless.
Also, the weight of the motor is quite less. It only weighs 0.68 pounds. This is quite less for a motor. So, it won’t make your Arrma Limitless too heavy and it won’t slow it down.

Hobbywing Ezrun MAX 4985 SL Motor
Next, we have the all-time budget-friendly motor. This is the Hobbywing Ezrun MAX 4985 SL Motor. This one does save you some money. But that doesn’t mean it offers anything less.
In fact, this one has a higher kV rating compared to our champion. In fact, this one has a kV rating of 1650 kV. Now, the kV rating indicates the RPM rating per volt.
As this one has a kV rating of 1650 that means it will rotate 1650 for 1 volt of power. Thus, with less power, you will get more rotation of the motor. Hence, it will be much more efficient.
Other than that, it fits all the MAX 6 ESC, 1/6th, 1/7th RC cars. So, if your Arrma Limitless has any scale that falls within this category you can easily take this one as a replacement for the original motor.
Room For Improvement
The shaft can be a bit weak. So, go for the Spektrum Firma Brushless Motor.
ARRMA 2050kV Brushless 6S Motor
Next, we have the ARRMA 2050kV Brushless 6S Motor. Yes, the Arrma brand itself provides replacement motors for the Arrma Limitless. But why should you invest in them?
Well, this one has the highest kV rating which is 2050 kV. Also, it is the most lightweight motor on the list. You see, it only weighs 0.46 pounds.
Now, because of the high kV ratings, the motor will rotate more times with one volt. As a result, they will be more efficient as they won’t require high voltage to rotate as many times as the other.
Plus, its lightweight function makes it a great fit for the Arrma Limitless. This is because it won’t add too much weight to the Rc car. Hence, it will be able to race at high speed.
Room For Improvement
The only downside is that the gears may not connect at times. If that’s the problem then go for Spektrum Firma Brushless Motor. They have excellent connectors.
