Brushless Aircraft Motors Are Different Than Other Models
When deciding on a model aircraft motor it is important to know the variation between the different sizes and kinds. Each aircraft has unique needs according to the weight and propeller dimension expected.
Commonly a model aircraft engine will work optimally with a particular size prop as marked on the engine itself.
Brushless motors are the most commonly used model of model aircraft motor used these days due to the fact of the high power to weight ratio as well as their sturdiness and capability to last a lot longer than in runner motors.
When deciding on an electric model aircraft motor be sure to verify its max burs amperage. When you invest in the speed controller you are required to obtain one that has a greater amperage than the model aircraft engine max burst amperage. So to make it straightforward, if you purchase a motor rated at 35 amps then the speed controller must be at the bare minimum a 40 amp speed controller. This way you can be sure your electronic components will be protected by the speed controller.
For slower radio controlled aircraft you will need a motor that does not spin to fast but one that is able to spin a larger propeller. This is ideal for trainer radio controlled aeroplanes with a straight wing.
For little radio controlled aeroplanes that weigh less than 300g for example you will need a motor as little and light as possible.
So in conclusion, you require a model airplane motor that is the right weight, size and amperage. Find out as much as you can, educate yourself so that you can make an knowledgeable choice rather than an high priced one.
