Eflite Comander upgrade question
 

I have a stock Eflite Comander and I love it! Am getting just under 5 mins flight time and would like to get more time and perhaps a little bit more vertical zip. I am going from a 3s 30c 3200 lipo pack to a 5400 lihv pack with 65-130c. Will I have to upgrade my motor and or esc? I don't want to lose this little sweetie to a burn out.
This is my first electric plane so I could use some advice.
Thanks, Scott.
