You asked for suggestions! Here’s a few Jeremy

Spare Revo plastic parts with RPM’s, at least one extra diffs or start to save up for these:
http://www.rc-monster.com/proddetail...flmrvdf&cat=44 , change out your springs and upgrade your shocks to GTR or ??, upgrade to 23 mm wheels and use crime fighters or Bow-tie 40s tires, upgrade your steering servo to something that is at least 190 oz torque, get a spare wing & body and upgrade to a 2.4 ghz radio system.
That's a great setup you’re proposing,

I'm running the Nue 1515 1.5y on 5s in my buggy and it runs great! However on 3s it's crap! / slooooooowwww... can you run two 3s in series totaling 6s?? If so you will be totally stocked!.. Gearing is good, should keep things nice and cool and still provide you with the on demand punch.
Keep us updated on your build and don’t forget about the Video!..
Have a great one.
