Minimum Power Requirement
I know this is kind of a difficult question because most here are concerned with a good performing aircraft. What I'm trying to figure out is what the absolute minimum power needed to fly a 10-15lb flying wing. I've estimated the stall speed using some calcs at around 17-20mph and doing some rough calculations, the power requirement for level flight came out to around .6 - 1.2 HP.
My question is:
1. Does anyone believe this?
2. Does anyone have a more accurate way to calculate this?
I'm trying to figure out what the smallest engine I can select would be just to barely fly.
