hey its great to see another person from las vegas drifting. personally i would take the 2 speed out because it is not necessary to dirft. you will only be drifting low speeds anyways. i would lock the front and rear and if you can find out if hpi made a front one way diff, i would look into buying it, make drifting a lot more crisper. thats all up to you though. the d box is basically a gyro, it just keeps a center for a drift, personally i would rather learn to drift without it.

good luck and message me sometime if you want to go meet up at the track and drift around or something.
