Some questions on converting my savage

[Savage03]

With flm's kit now it seems easy to do a bl conversion so im trying to crunch the numbers if I can swing it. My question is whats the combo most recommended? Now I have a monster savage

LST tires and what not so I need a combo that can move those nicely, I dont want a wheelie monster just something controlable to bash with. Can you keep the 3speed and have reverse?
Looks like the FLM kit is around the $200 mark so the next is how much the esc and motor are.
Thanks!
