Disclaimer:
All of the following factory settings are suggestions only and should be followed by people who know about tuning nitro engines. Any adverse results are the responsibility of the tuner and not BYNB.
Key:
HSN - High Speed Needle which will be highlighted in RED
LSN - Low Speed Needle which will be highlighter in ORANGE
IDLE - Rev Regulator which will be highlighted in GREEN
All turns should be followed as if it were a clock for example 4 turns out would be 4 times round a clock i.e 1 full turn being 12 hours if it states to 'Turn out' this is anti clock wise i.e left from 12am to 11pm to 10pm etc etc. If it states 'Turn In' this is the opposite way which would be clockwise.
