Losi micro desert truck brushless conversion?

I have a losi micro desert truck and I am not sure if it is worth it to put a brushless motor in it to get longer run time and faster speeds. Would it be better just to put a LiPo battery instead? The stock NiMH battery is just not cutting it run times are too short. I understand it is a micro and the run times wont be long. I would just want alittle longer run times and not sure what to do. A LiPo or Brushless motor. I would put a LiPo either way.

Both LiPo and brushless motor and esc

Go the conversion.... I converted my Losi Baja to brushless then ended up buying a Micro DT chassis and re building as I needed more space. It is awesome fun and runs for ages... Speeds it great for the size.... I put in the 10,000kv motor and losi esc..
