Good afternoon everyone, I am in the process of making a micro ornithopter, and I need to calculate how big the wings have to be, and how much lift they will create. (The Body at present weighs 25grams) 1. Is there a formula to calculate the wing area needed to lift a certain weight 2. Are there certain degrees the wing has to move through (whilst flapping) to create this? I have a few more questions but these can wait for the moment kind regards Th3Bozz

Just to say a BIG BIG thank you for the Reply, after down loading pages of Info I still couldn't figure it out. You've made it so Easy to understand. I look forward to presenting some other problems shortly kind regards Th3Bozz

Hello Everyone, Anyone I have recently built a model Rocket (Q-Modelling Nike-X) and I am interested in finding out how many Newtons of thrust I would need to launch it. The total weight without the motor at present is 330grams, is there a simple equation I can use to work out the above. Also could someone please explain g = 9.81 m s-2 It's the -2 (per second per second) I can't get my head around??? kind regards Th3bozz
