Hi Ranz, when you get it read the instructions (especially for the engine) a couple of times before you do the break in. They are spot on and will help alot.
Also if you want to order spare parts online try WWW.INFERNOSONLY.COM.;)
There is also a forum here on RCU called "KYOSHO INFERNO U.S SPORTS" where you will find alot of info about the MP7.5 whether it be the U.S sports or other types. Post a couple of pictures for us.(please)
