Bingo!

You would of course have to buy a brushed ESC separately (although I think a Brushless ESC works on a Brushed Motor - not vice-versa though)

And I thought that I was the only one who started fights....................keep it up guys!

Who's fighting? Who can fight versus the terrible shawm?

Thanks Rai sahib for the email address. How good or bad were the motors you had bought from "servoelectronics"?

VC Sir, tomorrow I will weigh the boat and also make another round of search for the missing prop and let you know.

They were "Johnson" a very reputed brand. China made, of course

@ashok baijal, Is this something that you can use for your project? t's a 300 sized brushless motor. Let me know.

Thanks

I can surely give it a try. See pm.

  

What should be the rpm range for the motor? Should it have high rpm, say in the range of 18000 rpm, or medium range, say, 6000-10000, or a low rpm say below 1000 rpm?

Alas, no!

Brushed and brushless motors are quite different items, and so are the ESCs for them. For a start, a Brushed motor ESC has 2 wires coming out, which carry a DC current.  A Brushless motor ESC has 3 wires coming out, which carry a multi-phase AC current. They are certainly not interchangeable.

A brushed motor can be used with or without an ESC. It does not need complex electronics to function. But a brushless motor HAS to have a special ESC because the brushless ESC contains all the electronics which make the motor work.

@Dodgy
Yes the two ESC are different but will try out the better of the two once I am back home. Currently busy caring for my dear ones in hospital.
