Default Power 46 Help 6.25 pound plane - Help

I tried to fly a nitro planes 330L electric, and didnít really have enough power to get off the ground - aborted... I am essentially new to electric - other than several 3D foamies I fly all the time.

I have an exceed power RC 46 670 Kv motor. I was using a 5S 30C battery and 13 x 8 prop. IR on the cells 12 9 7 6 5. Also should mention the Hitec charger timed out charging this battery (balanced). I left the default 120 minutes set for it.

I did the power math this AM afterwards and it is no wonder I didn't have power. 30C on 18.5 gives 555 watts on this 6.25 pound plane - basically not enough at all.

I have an e-Flite 60 ESC in it.

I just ordered 2 HRB 4000 22.2V 50C-100C 6S. I may have to set the throttle lower if the amp draw is too much. I put a wooden 13x5 prop on it. I also ordered an apc 12 x 6e and apc 12 x 8e to try.

Am I headed in the right direction? Do I have the math better for this pound plane? I like to fly 3D and would like hover power at 50-70% throttle. Do I need more motor and ESC?

6.5 aerobatic plane, put an XPWR 22 motor, a CC 90 amp esc and a Xoar 16X7 prop in your airplane and go have a blast.
