I built a track for the first time, and will be running it tomorrow for the first time and will fix anything that can be improved. Its a good size track that has 2 small doubles and 3 big doubles. The biggest should put the truck at least 8-9 ft in the air and travel for about 18-20 ft. If anyone would like to ride to it one day and run on it drop me a message and we will work something out. I plan to add more to it, but need something fast before thursday when my friend is coming over to race me on it.
