I really am having a tough time getting my head around all the new technology in the racing side of the hobby so I apologise for my continuing questioning
I'm considering the move to a brushless set up and have read so many threads on this topic that my eyes are bleeding

so I'm looking for some straight talking advice on this purchase. I am aware that different people have different preferences so I ask that if possible you put them to one side and consider the requirements of a brushless numpty.
I'm going to be racing mainly 2WD using TrakPower 4900s on a pretty slippery surface, the other chaps at the club seem to be running 6.5 combos.
I very much like the aesthetics and price of the Losi Xcelorin but there seems to be a lot of threads highlighting problems with these sets and all the talk of firmware upgrades has my head spinning.
So in essence I'm looking for a brushless combo (I guess that sersored is the way to go) that will fit easily into a 2WD, is easy to set up and run straight out of the box, has no serious reliability issues and is reasonably priced?
Any advice will be gratefully accepted,
thanks.
