Default Piper Cub 78.7inch electric convertion

Hello,
I am placing an order for the following products and want your advice on :

1. Is the product matching correct, I mean the correct ESC for the motor?
2. What battery should I buy to get at least 10-15 mins or more of flying time?
3. What else do i require (apart from the motor mount) for this conversion?

Rimfire 1.20 50-65-450 Outrunner Brushless
FlightPower 80A Brushless ESC w/BEC 2-6S LiPo
Rimfire Prop Adapter 50mm

If the above 3 products match correctly, please advise which Lipo battery should I buy? I would like to use these to convert from glow to electric on a Piper J3 Cub having 78.7 inch wing span with approx flying weight of 10.5 lbs. Currently, i am using OS.61fx engine with a 12X8 prop which does not give me any speed to do even a simple roll or a loop. the moment i reduce te throttle from full to 3/4th, the plane starts loosing altitude.

Really appreciate your advise.

Using [link=http://www.s4a.ch/eflight/motorcalc_e.htm]THIS[/link] online calc program, the 80 amp ESC might be to small. I used a 5000mah 6s battery, APC "E" prop 16X10, it pulls 85 amps with 263 ounces of thrust.

Might want to go with a 100 ESC.
