Thanks Brian, I wish you more spare time for the new project.
I am curios to see how well this wings' motions will work. IMO they are beneficial for close to zero forward speeds and "fyling with thrust" - highly energy demanding way of flying.These motions have to be diminished gradually with every next wings' beat proportionally to the increasing of the forward speed .When the bird flies already with cruising speeds /fling with lift- really economical and efficient regime in which many migrating birds are able to cover thousands of kilometers/miles without landing / the fanning motions occur only on the ends of the up and down strokes and have to be completed before the beginning of the new stroke for the best efficiency - best ratio: (thrust+lift)/(overall drag). In order to be abbe to accomplish this, you will need variable flapping amplitude mechanism at least on the rear spars.That's one good reason why Mike and Kjell efforts are important and I appreciate it .
later when the time allow me I will post sketch of a variable flapping amplitude for conventional crank mechanism which is simpler and do not face a problems whit actuation of the variable amplitude flapping .

Success!

Otto

Probably will be good to have such a device on the RC ornithopters.It can bring back your machine every time when it going out of transmitter range automatically or turn back and fly to "home" location just before ESC cut the motor because of low battery voltage .Free hands programed in advance trajectory flight is possible as well and the pilot will be able to film the flight himself.
