| Martin's Mono is the first pager-powered plane I made - inspired by the much, much bigger Butterfly. It has 8" wingspan. This represented a number of firsts for me - my own design, working with carbon rod, making carbon propellors, and making actuators. I was aiming for 1/2oz, about 14 grams, and was pleasantly surprised when it came out to less than 10 grams.
The first model had solid balsa tail feathers and a 10 ohm, 6 mm motor. Wouldn't quite fly. I convinced myself that the carbon rod tail would be lighter, but the real trick was in converting to the 4.5 ohm motor. I did have to increase the dihedral a little for stability in turns, especially right turns. Now it flies well, and I have clocked probably a couple of hours on it. The first motor died after a few flights, but the current one is still going strong.
