HI! I'm a really beginner in RC, its amazing! I just bought a HPI RS4 3 (not evo) 2002 edition and i want to hop up it... What i got to do first? Was a good choice? Thank you! Sorry but my english isn't very well.
 
yes, i just break in only 4 days ago. i want to know the first tuning to hop up. 2 speed transmission? racing clutch? pipe? AH... Yesterday i was buy a NIB sirio .18 (3cc) engine. i hope change it when i take more driving experience...
 
That sirio will make that car fly! If you are trying to learn on the stock mill with that single needle carb, it is going to frustrate the hell out of you. That stock carb is junk. If you really want to use the stock mill right now, you may want to change out the carb, an OS 10 e carb is a real nice choice but finding one is going to be tough.

Well since you bought a new engine already, (that sirio will make that car fly!) I would suggest a one piece tuned pipe, like either the THS racing tuned pipe, or RD Logics pipe, or the two speed tranny next, you're really going to want to replace both.

The carbon fiber upper deck and sway bar kit really helped the handling on mine a lot. But with the carbon upper deck you will also need a flat receiver battery pack.
