Sorry, I'm not dissing the Spektrum. Try to try one out, or at least download the manual and see what the menus look like before you drop the coin for one.
I think the DX2 has a two model memory and the DX3 has a few more, so you might want to be looking at the DX3... also, if you have need for a third channel (reverse on a nitro monster truck for instance) you'll need the DX3.
I have an Airtronics M-11 for my primary and an Airtronics MX3-S for my bashers.
I'm not familliar with that Novak ESC. I know the Traxxas one is quite good for a basher.
Gear down that motor. You can go 18.
