Jack Stafford B-24, estimated at 13lbs, 5-10 min flights

I’m trying to figure out if I can affordto go electric forthis project, and what it would cost in 2012 dollars (the stafford b-24 threads are at least 2-5 years old and quote old, maybe out of date parts).I currently know little about electrics, other than I think I’ll need about 950-1050 watts figuring a 13lb plane.

Any ballpark cost estimate would help, using reasonable but not necessarily top of the line components - thanks.
