Brushless motors
 

I Know about the numbers 6.5 etc but there seems to be a massive difference
On the price between different brands of motors what are the differences and is it worth paying the extra?

Bit to vague really pal. You cant go wrong with most premium motors. Id advise going sensored and just get what you like. Maybe read a review or two before you buy.

That or ask about specific motors on here, your question is difficult to answer ;)

Thanks Danny, well you can get speed passion for £50 ish and the likes of Orion,tekin are more like £85 ish. I know to go for a sensored motor.

speed passions are great motors and for £50 you cant go wrong, The likes of LRP, Nosram, Orion etc are more money but IMO are better quality. So the choice is yours whatever happens if you stick with a well known brand you will have a reliable motor :)
