What would be the best brushless set up for my rustler. i will be bashing it all the time. i want to stay with novak

I will be runing it with
Pro-line M2 Moab truck tire
Ball bearings
2400mah packs and 3800mah

If i go with this set up what should i do with my gearing?

I would go with the Novak 4300 motor and super sport+ ESC.

As far as gearing Novak has recomendations in their manual.

My choice would be the 5800. My criteria for a bashing truck is "fast enough to be interesting". As you drive it more you will begin to want it to be faster. If you go with the 5800 and it is too fast initially, you can gear it down and extend your run time. Then when you get used to it and want it faster, you can gear it up again to go faster.

(An aside: my favorite bashing setup for my rustler is 7-cell GP3300 packs and a 19T motor with standup brushes and adjustable timing set to zero degrees. I get 9-11 minutes run time on well-worn 3300s even though I am on it hard the almost all the time. This is definitely "fast enough to be interesting".)

i would also go with the 4300 motor and the super sport ESC,
