Hi John, Id just like to point out that you can make an antweight with batteries, motors etc and fix it all together with Selotape. (http://windisch.co.uk/robots/howto/build_a_robot.htmhttp://windisch.co.uk/robots/howto/build_a_robot.htm)Try doing that with a feather and then tell me how much easier a feather is to build than an ant. Nothing against feathers, and they may be price-comparable (not if you build them with the servos that came with your transmitter though) but I would say that ants are easier to build, and more child-friendly, IMHO.
