The better the questions, the more info, the better the answers can be.
E.g. you would not be the first one to mistakenly assume that prop thrust must be higher than plane mass in order for a plane to be able to fly at all.

As Nigel suggested in post #2 e-calculators such as www.ecalc.ch (18 languages) can get you in the ball park (software: garbage in, garbage out).
A watt-meter is a must, it will let you check/refine/debug your new/changed power system, and watt-meter will pay for itself several times over.
