GEt the LRP .28 its i direct bolt in, extremly easy to tune and it takes 4-5 tanks to break in. when i gear it 18/47 and it still pulls wheelies. the 4.6 and the 5.9 are good motors but for the same price the lrp kicks their rear ends! bte get the hpi bulletproof hardened diff gear sets for the front and rear. with a 5.9 or a lrp 28 the diff is gears are not strong enough. ive gone through many gears in the diff
and i say get a rotostart, those pullstarts a pain in the @$$ they pull out alot and if your engine is not perfect tuned its a pain to start. The lrp comes with an internal one way bearing end it has never failed on me.

You will need to buy the backplate adaptor for the rotostart which i cant find on towerhobbies
