Long time Kyosho driver. I have also owned a couple of EB48's. I'm excited about building this NB48. I got a couple of questions....didn't want to bother my team manager. What size is the flywheel? Rear motor position not very popular? What is the equivalent to Tekno 450 or 350 oil...and the Tekno diff oil? I don't think Tekno sells oil. Good starting point box set-up or Lutz Fall Brawl or Battle of the Sickest? 6 washers on Ackerman popular?

Thanks ahead of time. I am sure I will have more questions.
