Motor combo suggestions

[MentillStitch]

I almost want to purchase the mamba max pro with the 1415 series motor to run but dont know if it will be powerful enough for the truck. I had their 4 pole 3800kv motor on 2s in the truck but it wasnt that fun to be honest. Now the diffs were unlocked and the motor, using the stock pinion, was probably under geared... what do you think? It would lite up the tires and torque twist like a contortionist on crack but it would onlly do about 5mph.

the diffs are locked now... I do remember it cogging a lot though. dont know what to do. I want to be able to crawl with it but also pop wheelies and atleast be able to run about 15mph.

What do you guys suggest? brushed setup or sensored maybe? Am I asking too much? I guess an emaxx transmission swap would be a big help with this but I didnt want to get into that right now.
