You can jump, jumping again may be enough?
As long as you going up and not falling, do you think BodyWings© would be enough?
Raising the wings after each jump should be easy as the wings surface is made of hinged flaps so the air flows through the wings.
Some people can run 26 mile marathons...
(I know your about to jump up and down using my motion, it's quite enjoyable.)
Also, material advice for the framework would be great, I'm thinking creating moulds and using fiberglass and resin.
