I ran a Hitec 985MG on steering and 645MG on throttle and brake in my Losi 8.
Crimefighters are o.k. might want something like some Badlands as well, any 17mm hex wheels should be o.k. as not many buggy wheels run an offset.
Personally I find OS No.8's are a good starting point as an all round plug and you can go up or down a grade depending on temps.
A good all round pipe is the Jammin JP4 if you can afford it if not a Hong Nor 053 is a pretty good cheap pipe.
The starter kit's are o.k. and you can then add or upgrade them as you go along, you'll need some imperial hex drives for the Losi as the dear old yanks haven't discovered metric yet.
