Nah he just need to start leaning it out, high speed needle first then low spd needle. That's all

My RS4 had a .15 CV and ran as fast with only .65hp! Something's not right here, this engine goes for 1.35hp... This car should be pushing over the 90km/h line

the box on my rs4 3 evo does 65 mph out of the box, great car, though my electric rc18r is 2 times faster with exotec carbon kit

i think you can get this to 70km/h, change the gear ratio to suit the engine.

[traxxasman4life2010]
