Well, heres some stuff to think about. First off, with the muggy, you'll be changing the clutch shoes right away. They are prone to failure. While the muggy shares some components with the LST2, it does not share the nice synthesized radio... So you are no better off having that. For me, one of the big disappointments with the Muggy, was the lack of thought put into the suspension. Mainly in one area. Team Losi shortened the shock shaft, the shock body, and the shock tower. However they forgot to shorten the springs... You'll find yourself hurtin when it comes to proper suspension setup.

With the Hellfire, you have more setup options. The towers, the springs, etc. And its already equipped with 17mm hubs. So you are ready for some racing treads. If you buy the SS, you'll be supplied with em. Now personally, i've seen TQbatman punish his Hellfire RTR at the races. I cant see how he can claim it sucks. I do feel the Hellfire is a little pricey for what ya get. Though the SS Hellfire i believe is available, or soon to be available with a motor. So that might make the deal better.

Regardless, i think if i were to choose from those two, i'd take a Hellfire... Though i think you'd probably enjoy them both.
