can some one help me with my rc nitro I'm a noob at this i just bought a 1/8 scale and its too speed but it doesn't shift to the second gear. please help me out.thanks for your time.
Before you mess with the shift point you need to make sure you're engine is tuned for performance. If the engine is not hitting the rpm the tranny needs to shift, then it will never shift into second gear.
In that case it could be a couple of reasons its not shifting. One is that if its running too rich it wont shift. Try leaning the hsn in small increments after the engine is warmed up until you see the performance getting better. Here is a link for tuning. If you follow it to the T your engine should be performing to its best potential. http://www.extremercmods.com/content/tuning-popup.html
