got it, broke it in, harder to tune right than my 4tec, but let me tell you---i love this buggy. my g/f son (6 yrs old) stepped out in front of it at about 30 and it took his feet right out from under him. didnt even hurt the buggy---and he is alright also. i have yet to even put the 9mm throat in it, i figure i should get used to the buggy first after i saw how fast it is. and the radio that comes with it is amazing to be in a rtr kit as far as the adjustability of it. i have not had a problem with the brakes on it, it will lock the tires at will and rip grass up or tear knobbies off of the tires on asphalt. i have not had a problem with the clutch yet either.
