mud bogger? 10th or 8th scale? new to this whole thing

[tha5150]

i have some experience with buggies, emaxx, drifters. i think i was to attempt a mud slinger or bogger. no 8th scales? only 10th? what would i need to look for as a cheap, first timer chassis, etc. i dont think my Medusa 2300 would do good for this so i guess i need motor too. what size? just a titan 550 maybe? i could pick several of those up for pretty cheap. anyways, i have no idea what i am looking for and i want some help

what i want needs to be waterproof. this is a defiant.. i would like to end up with some sort of scale look but this isnt needed at first. just a decently painted f350 body and some big mud slinging tires. i would be content with that. i have a Spectrum DS2 and a Futuba 3PM FM system. maybe i can tie the receiver up in a bag and seal it? still need an ESC and servo.

who wants to start with some tips..
