Which SP motor ?

[madwestmo]

Im after a new brushless motor , I want to stick with speed passion becuase this is what i run in my TC

Im after one for a 2wd , Looking at a 8.5t as i aint a brilliant driver yet

This is where i dont know what to do as speed passion have 2 8.5turn motors....

The v3.0 , Around £75

The v2.0 (but newer design then the old ones??) This one costs half the price at £35

Now i aint going to be winning any championships so am i going to notice much differance because obviously the price differance is alot but obviously for a reason ?? surely the adjustable timing doesnt double the price ??

What would you guys suggest for a relative beginner to offroad ?
