Newbie needs advice On 1/5 scale buggy

[OldGuy]

Hi ALL

Just found the forum, and would like to say HI to everyone. I've read the thread on HPI VS KM buggies and think both sides have merit. That being said, I could not find enough reason not to buy a KM Baja. Bought it on eBay from Heat Hobbies, delivery scheduled for 10/11. I am a total newbie to R/C trucks although I have R/C experience with helis, gliders, fixed wing powered planes and sailboats.

A couple of questions on the KM Baja:

1) is there anything I really, really should know before I go for my first "ride"

2) I noticed in one thread that some folks use Coleman fuel in their buggy. Is this recommended?

3) What are the first mods that you recommed it improve a KM buggy?

Thanks in advance for your help!
