Newbie here need Info on set-up.

Hi guys I'm new to electric rc. I see it's mostly monster trucks but i think you can still help me out. I have a tc3 on-road that is stock. I love it! Even though it only last abut 5-6 mins a charge. I wanted to get a better motor and battery so it was have longer run time and i think brushless is the way to go? Power is fine but i'm mostly looking for long run times. I have a $150 - $180 budget for a brushless motor, esc and lipo battery. Could someone point me in the direction of what to buy or if they sell a complete set or if i should piece them together. Oh Also I will need a lipo battery charger hopefully not over $60-$70 for that. Thanks for any info. I can't wait to see the potential of this little thing!
