I wasn’t planning to blog any of my contributions to Keith’s big diorama independently here. Then someone told me that they thought my helicopter was the best thing I’d ever built. I thought that in that case, maybe I should post it, in case I never match it again. I hope other people like it as much my vocal friend does. I have to give some credit for the dual-interlocking rotor idea to Tim G, as I first saw the idea on one of his creations.
