Firstly - a 25% off coupon at TH won't work on a Sl4sh... try to go through to checkout, and you'll see Traxxas don't allow the use of discount coupons.
Secondly - a Platinum edition is a great idea, but run it on 2S first, you may find on dirt/gravel 2S gives you plenty of speed. Always remember all the power in the world is no good if the tires can't give you traction.
Thirdly - stock Sl4sh tires are utter rubbish, especially for where you're considering running. Proline Badlands are the way to go.
