Hiya Mike, check out Trade-me. There's 3 on there now, starting bids as follows one @ $450.00, one @ $500.00, and one @ $590. Go for the Mad Force dude, I've got one and it's the Dog's B******s. Ideal for that Golf Course, and whatever else you throw at it. Really tough truck, with the solid axles. No fears of snapping one of the poxy little drive shafts, like all the other Nitro Monsters have.
Once you get over the run in process, (which takes time if you do it wrong.[] DOH!!)it hauls. 3-speed trans on the Mad,46mph top speed right outta the box.[}] 1-speed trans on the Mega, top speed 18mph.[]
So far I've had mine at the Wiamak river, (on the dry bit lol) out on the road outside home, over the road and into the neighbours yard, climbing over my rock garden. Going to the local skate park soon, just to stir. Then I'm going to the local BMX track for some air-time.
Like raemin said, lots of up-grades. Can add another set of shocks if you want, I will be doing that soon.
Anyway that's just my opinion. If I was you I'd go for the RTR, just for the ease of not having to build it. It's a pretty basic set-up anyway, so if you had to strip it down it'll be simple. I had a look at the Traxxas Revo, the only thing I liked about that truck was the body shell.
