Small-scale warbird: A challenging micro build

摘要

In the palm of my hand I hold a tiny motor—less than 3/8 inch long—and a tiny battery that's 1 inch long by 1/4 inch wide. Can I possibly build a 3-channel RC model powered by these ridiculously small parts? Using some basic estimates, a couple of cal-culations showed me that my biplane would have to be around 4 inches in wingspan, with a total weight of between 2 and 3 grams! I had never built anything that small before, but I had seen some other scratch-built models that were just slightly bigger, so it seemed possible. OK; the game is on!
