Buggy to run competitively at Wakefield ?

[andys]

I went over to the new Wakefield track today, and really fancy getting an 8th buggy to run.
Ive read the previous 'which buggy' posts, so here's another !

ideally I'd get an RC8 after seeing one in the flesh. Thing is I don't have that kind of cash, and I know NOTHING about nitro. I've run 10th electric off road for decades, so can drive pretty competitively, so I'm wondering will any of the RTR kits be any good. Some look like super value ?

Any standout recommendations for a Nitro Newbee ? I like the idea of RTR as I get everything o need in one hit, although I like the idea of building the kit too, its the whole engine / setup stuff that scares me and I guess there's plenty of help with all that in an RTR kit ?
lastly, what are the engines like in the RTR kits ? What do I need to be on the pace ?

Cheers.
Andy.
