If I had to have 1 engine to run depending on track size and how deep the sand was I would go with the 7 port. spend the extra money and have it modded you will not be disappointed. From what I'm seeing out of my gxr3port,I don't think it will be coming out any time soon.
I do get my parts from racer 22 but I can't justify spending money on the mod. Where having a hard time keeping nitro going in West MI so there's not alot of races or mutiple tracks on the same day and nothing the next weekend.

The 7p runs great exept on 30 min main where it leans it's self out to much. I might try the 5p this time and see how it compares since 75% of the tracks are fairly large. Not sure the 3p stock would have enough grunt down the long stretches. Wish I had money to get one of each.

The 7p has been my first true race eng and I love the GO.
