Newbie here, ?'s about what to buy.

[ToddD81]

First off hello all and thanks for a great site with lots of good info.
Now on to what I have. Im am new to the whole rc world and have an emaxx with a few upgrades I just purchased.
Gorillamaxx carbon fiber chassis & motor mount.
Integy shocks, a-arms, shock towers, f&r bumpers, chassis braces, skid plates and body posts.
Once I get all of this in I plan on looking to get a new motor and batteries, but have no clue as to what to get. Any advice would be much appreciated and I'd like as many opinions as I can get also. What I'm looking to spend more is around 750 or so. But I would like to get everything else I need. I would like to upgrade the drivetrain parts to what I need to hold up to the power. Guess first off I would like to know what motor and esc and batteries would be the best. Im not looking to get a whole lot of speed, but would like to at least leave behind a stock 3.3 T-maxx. If I need to go beyond the budget then o well guess I will. But if you guys could give me some info and some links on what I should get. If you would go into specific detail that would be great as well seeing that I know about next to nothing on batteries and brushless motors and whats good and not. I was considering gettting the hv-maxx 4.5 setup since its not too expensive and seemed to be like it would be easy to install and do. But from what I've read on here seems like they are not that good.So to sum it all up im looking for a complete listing on what I need drivetrain, motor, esc, batteries and a charger/accessories. Any and all input would be greatly appreciated and I will most definately post pics up when i get this project completed. Thanks in advance to all you contribute to my work in progress.
