HPI NITRO RS4 Running and Head Mod
This is ALL STOCK!! Just a new engine and homemade intake air filter, I cut 2 fins off of the heat sink head so my body will get lower and beats of buying a new head also its very fast for a small rc car with the help of the HPI Nitro Star T-15 and new clutch that i got (since the oldf clutch bell was worn and shoes also). Since my old .12 died and a new .16 cheap china rc engine i traded them for a Palm Treo 680
