right now your front is too thick. with 10k in the center and 7k in the front the center can't spin the front as easy as the back. so your getting a little too much power to the rear. most of the time you should run 3-5k up front. a good starting point is 3f-10c-5r. you want some powerup front and a little more in the rear. right now you have it backwards. understand what i'm saying?
Everyone by me always runs thicker oil in the front then in the back that is why I have it like that and it is like that on the other truggies I have but this mantis is the only one giving me a problem. You are saying opposite.
