Please use the search function and try to do a search. There is a thread about tuning stock motors here. I believe there may even be a thread with regards to tuning the Binary.
It seems that there have been a lot of new threads posted lately that are repeats of existing ones, and these have been authored by newer users. Perhaps, futureal needs to make the "Forum Rules" section a much bigger click lol. Please do a search, there's a HUGE repository of information here.
