The track we race on has a front straight that's 170' long. It was dry slick so I was running my 1600, during practice just for the fun of it I put in a 5s pack. I would give almost any thing to have a picture of what the front tires looked like at the end of the straight, my guess is about 9" in diameter, I could be way off but they looked like they were going to fly off the rims at any moment. Good think I use AKA glue or they probably would have flown away. Oh by the way my lap times were pathetic with 5s setup, way too much power for my skill level. No I didn't turn any thing down. I put a 4s in for the main and came in 2nd for the day and for the season. Hot Bodies d8t Tekno conversion, awesome setup imo! Can't wait to upgrade!!!
