Difference between electronic brands?

[alanwheeldon]

Ok so what is the difference between say a Speed Passion 6.5t motor and a LRP 6.5t motor?

The price is double for the same turn motor so what are the benefits of spending the extra cash?

Would it be quicker or is it just build quality and reliability or is there no difference?

Same applies to lipo batteries to??

Im trying to work out if its best to buy brand new cheaper gear or spend the same amount of money on second hand higher end branded gear

Cheers guys
