I race both on small and large tracks with ns3 motor . The r40 definitely needs a taller second gear. I find myself backing off the gas half way down 180'-200' straightaways. Most of the time I find myself passing up races on very large tracks because I dont want to blow my engine. I'm planning to do the .8 module conversion.
What size tires do you run though? 57 mm or 65 mm; makes a huge difference.
