can a brushed motor fly a RC plane
if yes how?
if no why not?
I think you need to do some more reading before asking such questions. A lot of us on this forum have built and flown planes that used brushed motors since that was the only option we had. When brushless motors were first introduced, they were very expensive and most of us could not afford them. Brushless motor technology and battery technology has greatly evolved enabling rc enthusiasts to build lighter airplanes without sacrificing power. To answer our question, yes, you can build and fly an airplane with a brushed motor with high rpm. Whether the plane will fly or not will depend upon your design.
Hope this helps.
Use a good Brushed Motor with Lipo battery you can have decent thrust for a trainer plane.
i am thinking that brushed motor are heavier than brushless and brushless motor have high speed
On what basis you made that not completely correct assumption?
Before you can even understand the answer you seek. You tell us what do you understand by the word brushes which iverbatim a brushed motor and not there in brushless. What is its functions, advantages and disadvantages.
If you don't know you can Google and post the answer you find mind you not the link to answers i need the answers verbatim.
PS : you would be surprised to note Google will link you back this forum for the answers you seek.
sorry sir
Why sorry Ayush. I am not taking this in wrong way at all. When you find answers to my question you would have defenitely found answers to your question too. From this very forum.
To tell you in short brushed motors have been flying planes for many years before brushless arrived in RC arena and are even today flying RC planes for sure.
PS: There is also a search tab right in the top in the center in this forum too.
Can't think of any reason to use a brushed motor nowadays instead of a brushless one.
Even though it is possible.
The power to weight ratio will usually be far better with a BLDC.
Recently replaced a brushed motor (and its 6:1 reduction gearbox) with a CF2822 BLDC.
BTW, like Col Sundaram, i too am a little puzzled by your queries. Hard to believe that this thread/query has been posted by a person having experience of a model jet turbine. This is not a criticism, just puzzled, that's all.
Regards.
yes brushed motor can fly a trainer model.But it has many disadvantages over brushless motors.They use lot of power,heat up,are less efficient,and weigh more.If the motor is fixed on puller type trainer then you also need a gearbox.
