futaba 3vc help needed

[rondoolaa]

hi,

i'm asking this for a friend as i tried to help him last week but couldnt suss it out,

he has a futaba 3vc and both him and his son race the same car with the same handset,

instead of going into the settings each time and adjusting the epa / atl he wants to set up the "knob" as the adjuster so he can speed up or slow down his car just by twisting the "knob" to the desired value for him or his son,

on the 3vcs its very easy, you go into menu 2 then func-dl then adjust "knob" settings until it reads "atl"

but on the 3vc i cant suss it out and hes new to rc so hes even having problems even with the manual instructions,

if someone knows how to set the "knob" up so it adjusts top end speed then please reply in detail how to do it, stating what the screen should read and what to press in each step,

he and i would appreciate the info,

thankyou
