Well, that's all good and well to have verbal descriptions of how you wish things worked, but until you do some analysis, determine the center of gravity and the aerodynamic center, see if it is vastly different from the center of pressure, and look at longitudinal stability to see if it's positive or negative I really don't think you have any data to support your assumptions about control via moving legs; if the center of gravity is forward of the center of pressure you will need a corresponding torque to offset the tendency of the machine simply nosing over (airplane tail). [edited to add; Conversely, if the c.g. is far aft of the c.p. it will be difficult to get out of hover]. Transition from hover to forward speed will be very tricky with a constantly changing center of pressure and gravity as the body flexes. I have no idea how you propose to transition from forward high speed to brake mode....
I especially have concerns about the ability of a human body, with an engine cantilevered off its shoulders, being able to exert controlling torque to guide this thing. The body is not a rigid structure and especially at speed I seriously doubt that moving legs around will give control. This is not sky diving or wing suit flying. You claim lift from the body and lift from the motor; how do you reconcile these? Also, the body would seem to be more hanging and causing drag than providing lift. Most lift from the body, I suspect, would be kite lift thus requiring even more power. As I have mentioned previously, in a vertical dive your device looks to be stable, which would be an ugly situation.
If you've analyzed all this stuff and come to good conclusions I would be interested in seeing your work. I thought about doing it, but lack data, time, and motivation. Your motor is interesting and kudos for building a running model.
