Hey guys,

I have decided i want to go electric. the Mojo 40 is built, and it is ready to cover, now the powerhouse of this thing... i need help.

I am was planning to use a os 50sx with 8oz tank so total weight would be roughtly around...
14oz engine w/o muffler
8oz tank
2oz misc
Total of 24oz

A123 battery.. i need help deciding between 5s1p or 5s2p. the problem with the 2 parallel that it will be a bit on the heavy side.
I was going to do just 5s1p pack. But flight time is decrease significantly....

So what i need help is with the motor. i need something that will hold this plane up around half throttle with flight time at least of 6 min. it this possible?

the plane is around 4-4.5lbs ready to fly with a .46 engine.
