Well, my little Go 5 port ran like a champ all day of the mo rc pro series yesterday and gave me more than I needed all day without needing the needles set all day. low 90's and it purred all day coming off at about 212 to 226 all day without touching it. Could have leaned it out for more power but traction was more of an issue than power. Front diff went out in the beginning of the main, so it got a rest. I know another guy running a 7 port Go in his Truggy (Serpent 811T) took 3rd in intermediate truggy and was screamin!
Hey and by the way, I flamed out twice earlier in the week during practice with a 97T plug in it, grabbed a 77T by mistake (found out after looking at the package later) it purrs now and seems much happier with it in there. FYI
