One of the most common newbie tuning problems I've come across on here is instant stalls on throttle or when the starter is removed. Once tuned your car should have a fast smooth acceleration, impressive top speed, steady idle and ALWAYS a good trail of smoke Turn clockwise if its too slow/low - eg revs drop then stall, stalls on throttle or wen starter is removed. Turn anti clockwise if it runs too fast at idle - wheels spin with no throttle Your idle may be affected after these changes, make adjustments in small increments at a time, Too Lean - little or no smoke on acceleration/immediate stall on throttle or stutters / high engine revs Too Rich - Lots of smoke and unburnt fuel at idle/slow acceleration/stall If it stalls, stutters with high revs / no smoke on acceleration then turn anti clockwise 1/8, if no good unscrew another 1/8 - this should be enough Note: it takes time for the LSN adjustments to be visable, it helps to accelerate at full throttle for 5 seconds then brake and idle for a few seconds then accelerate again, repeat until u see the improvement in acceleration then carry on making adjustments. You are looking for a fast and smooth acceleration with some smoke, a steady idle with some smoke and a bit of unburnt fuel won't hurt The LSN is very sensitive and u can potentially cook your engine if its set too lean. Tune the LSN in the same way, but only make adjustments in very small increments at a time. Too Lean - Little or no smoke/very fast/loss in performance at full throttle or stall - Turn anti clockwise Too Rich - Lots of smoke/slow-poor performance/stall/groggy sound to the engine - Turn clockwise I am going to call this the longest running, nitro name in the rc hobby. Turn the HSN clockwise (Leaning) in a 1/8 increment and drive down a straight, each time you do this you'll see a small increase in performance (and a good trail of smoke), keep doin it until :Ī : theres little or no smoke from the exhaustī : the cars gets slower at full throttle (down a straight) or stalls at full throttleĪt this point turn anti clockwise (richen) 1/8, if its still no good turn another 1/8 that will be enough Traxxas Nitro Rustler The Oldest Name In Nitro RC Gets a 3.3 Engine Make Nitro Great Again. Note: Most engines are happy with changes to the needles in 1/8 increments however in my expericience I've found Traxxas engines to suit 1/16 and also Cen engines, tuning them using 1/8 increments will only have you pulling your hair out Its should very rich(boggy/lots of smoke/ possible stall) at these settings and performance poor. Tune in order, make sure the car is at its base settings - the setting u broke it in with.
