the reason im looking to upgrade is that myself and another club member both ran the £115 LOSI combo.
We were both always left behind on the straights, and after trying various settings on the ESC (via PC hookup) we could never get the same amount of acceleration as others even after trying various pinions out.
The other club member just bought a LRP X12 and a new ESC (sorry dont know make/model) - but now his acceleration and top speed matches the other members in the club....while im still being left behind on the straights.
The other thing I notice is that a lot of the member cars can litterally 'doughnut it' (for a better term) it on the spot (due to the power), where as with the Losi combo we end up doing a circle the size of a Tractor Tyre
So either between the 2 of us, we havnt found a setup that gives us this power .... or it proves a LRP X12 motor on its own gives more power than a LOSI combo
So thats what got me thinking an expensive motor and ESC works/performs better than a cheaper version. I understand that realiabilty may be better with a more expensive model, but im thinking more out speed/performance - than fans breaking etc.
