If you're really good, only hover in place and have zero payload, you can get 90 minute flight times. (Which, I believe, is the record for enthusiast electric multicopters.) My guess for payload of an electric multicopter would be up to 5 kg, but the tradeoff is flight times in the single digits of minutes.
