Default Great Planes Learjet Electric Conversion

I am in the process of building a Great Planes Learjet and would like to convert it to Electric. Most people that have posted about their nitro lears say they fly best with a .70 size motor. What size Electric motor should I be looking for as well as Battery size for 5-6min flights?

Most folks are running these type models with 150-200 watts per pound. So, with an 8 pound model, that's 1600 watts, 800 watts per motor.

Perhaps one of those programs such as www.motocalc.com might be useful.
