There has been alot of interest lately in various flying machines. I've priced out how much it costs to buy the supplies for various aircraft, but the economics works best if I can order about 5KG of stuff all at once.
Along that thread, if I make an order of multicopter parts, who wants in. it's about 100$ a copter for all the parts, you just need to assemble and wire it up. (transmitter not included) plus your share of shipping.
