RE: crawler=£££?
The parts no rc4wd are excellent, but way over priced. Making your own links is very easy. It's your choice wether to buy a chassis or make one. The Gecko 2 is great, but I would get the new gecko pro kit.(It is not shown on website) It includes: Gecko Pro 60/40 split chassis, 4 wheel steering kit, adjustable motor mounts, axle braces, & a custom set of 8 tooth pinions. I believe it is $283 + $25 for S&H. Not sure about the t-maxx roll cage idea, might work..
