does it really fly??

[royalestel]

Absolutely. It would fly longer and better if it had an electric motor instead of a rubber band, but it does indeed fly just fine.

adding the motor would be easy
the real challenge would be adding a rudder to remote controll it you could use a miniature rc submarine motor and board or
fust buy the havoc avenger and use the electronics from it as weel as rudder only problem is short range and a free flow rudder  

[Mr.NHRA]

 The radio instillation would be easy! If some one made one of these i could convert it to an rc model in under 24 hours! The difference in my model from yours is that i would use servos and an ESC instead of cannibalizing an rc helicopter. I would totally make one of these but I am to inpatient to glue all of those bamboo rods.

 i used a rc car to make a plane, but i broke the reciever I think.

[toxicwolf]

first off you could use balsen wood and second the havoc avenger is an ornithopiter as well but the why it flies is hard to control and is adgetating

I made one of these, and the wings won't flap. is it because the crank isn't straight?

[GreenAce92]

i have made one of these before, except its a singlewing type, not dual. It flew only so far, they neeed alot of torque to flap the wings. I have a vid of mine on youtube called Jacob's Ornithopter, its made of popsicle sticks lol.
