I will be purchasing a brand new Spartan within the next few weeks. I have done a bit of research and know the boat is "6S Lipo"compatiable to get the boat cloaser to 50mph. I also have seen the boats engine benifits from a cooling upgrade requiring two tubes instead of the one from the factory. Where can I get these upgrades, and is there a write-up somewhere on nhow to install them? I have also noticed different propellars can be added to increase speed. Also, does the instruction manual that comes with the boat explain the trim and how it needs to be adjusted to suit desired driving types? Thanks in advance!
