Paul only a mother or your friend could love that profile. That they fly well is beyond dispute but they are ugly birds. Even a buzzard is pretty by comparison (well on second thought, maybe not). But close.

Remember a few years ago when Paul MacCready built a flying model of a pterosaur configuration. He used electric motors and seemed to solve the problems inheret with the configuration. There was also the use of some elastic bands to help smooth the flapping and aid in some energy recovery in each cycle. I believe he used the toothy part (did they have beaks?) and the head for directional control. I am not too sure the model could agressively climb from the ground. It was bungy/dolly launched and it did make enough flights of extended length to show the configuration that they had was workable.
