Need some advise for changing from brushed to brushless

[stebedford]

Ok, so I know about the different types of brushed motors and esc's out there at the moment but when it comes to brushless I havent got a clue, at the moment im running a 15*3 brushed motor, I do want to change it to brushless, but no idea what the different types are, whats the difference between the number and stuff? what speed controller and lipo would I need for brushless motor, ive seen people talk about 8.5 motors but still no idea what the difference is between an 8.5 and 13.5

If anyone could shed any light on it I would be greatful, and also any suggestions for any cheapish/beginner brushless setups would be great

Very approximately - If you divide the brushed motor wind by 2 - you end up with about the same brushless.

IE 13 turn brushed is approximately a 6.5 brushless.

so a 8.5 is faster than a 13.5?

Yes the lower the number the more powerfull the motor is.

ezrun systems are good value for money from ebay. they usually come with a 8.5T and run well.

That's a bit too generalistic I think as a 6.5 is way quicker than a 13 IMHO, though lipo skews it slightly.

8.5 = 12 or 13 turn
7.5 = 11 turn
6.5 = 10 turn
5.5 = 8 or 9 turn

If you want something the same ish speed as the 13 I'd go with an 8.5.

A 10.5 I think is suppossed to be roughly equivilent of a 19t motor
