Greetings!
I am currently working on my outfit for SteamCon in Seattle, and I could greatly use some help with the one part of my costume that I cannot wrap my head around.

I would like to make bumble bee styled wings using wire and a opalescent cellophane material. No problem there. The problem I am having is that I want to mount them with a servo each so I can press a button and get actual movement- but I do not know what kind of servos to buy. I haven't determined the weight of the wings because I want to buy the best servos for the lowest price and then decide the wing design from that.

Does anyone understand concepts like torque load?

Thanks for your help!
