Wow what a difference didn't really expect that!! mounted the box next to the battery box where does everybody else have their's ? Set it to 7 when i put it on and ran it for yesterday and have now progressed to 8 i think that will do! lol i'm used to plantint the foot in 2nd and 3rd and it wants to rip up the black stuff i'm not really botherd about much more power it seems to do what i want it to do now! I know other engines are different but anyone else have theirs set higher?
