Hi all,

After following multiple conversations, videos, forums, etc, I have a common understanding of the general workings of the average 1/10 scale crawler. However, I am a little confused on a couple points.

I intend my first purchase to be either, SCX10 Honcho, Deadbolt or a Trailfinder II

I assume if I were to purchase a waterproof RTR or a kit with waterproof electronics, I just have to install the appropriate LiPo, and away I go. This of course includes knowing the do's & dont's of LiPo care. Or, are their still components I have to install to accomidate the LiPo.
(I intend on running a 3 cell)

I get foggy when it comes to the when a BEC is required, and what if there is another built-in BEC on another part on the unit? I have to be sure I don't fry it before I take my first run.

I have searched using several combinations of wording and what I have found so far seems to be pretty vague on the requirements and normally all relate to a "brushless" motor, not "brushed". I can't seem to find a video on this specific area. No doubt I have dropped the ball. I'm sure it exists.

I am looking for:
"requirements and instructions for a 1/10 scale, brushed, Off-Road crawler, to be waterproofed and S3 LiPo ready"

Can I be kicked in the right direction guys? ( & girls)

Thanks!
