RE: smallest 3D plane you know of?
We scaled down the Tensor to 14" wing span. Comes in a bit heavy, 2.9 Oz, using AON T1215-4100 motor, Phoenix-10 controller, three Cirus 4.4 servos, and Berg 4 ch receiver. It's fully 3-D capable, but it's very quick and will get away from you in a hurry. I think that we can shed about an Ounce off the next one which should improve its flight characteristics. I'll get a pic of it ti post.
