Contact is made by the brass pin (left) being squeezed against the multiple strands inside the plastic insulation tube (right).Īnother innovation was hinges for the control surfaces like the rudder, ailerons, and flaps.

The socket on the right is a 0.1″ length of plastic insulation from 32 AWG wire, with the strands from the other wire drawn through and around, and covered with 0.020″ shrink tubing. Micro plug and socket The pin on the left of the photo above is made from a 0.1″ length of 0.010″ diameter brass rod soldered to a wire lead, supported with 0.020″ ID heat shrink tubing. Whenever possible, connectors are avoided entirely but sometimes - like to connect the custom-wound motor - it needs to be done. All the usual off-the-shelf connectors are far too big or heavy to go on such a small device where every fraction of a gram counts. Two documents ( Part 1 about techniques used for small aircraft and Part 2 about the P-51 Mustang pictured) are worth a read. In true craftsman fashion, he’s aware that while he rolled his own solutions and wasn’t aware of any similar prior work, he would be surprised if none of his innovations had ever been done by someone else before.Īt such small scales many problems need re-solving, like electrical connectors. shares some of the techniques that went into the many specialized parts of the plane. Apart from the battery, everything in the plane was built or assembled from scratch.

It even includes working navigation lights and flashing cannons (both done with 0402 LEDs) and functional, retractable landing gear. There are individuals who push tools, materials, and craftsmanship to the limit in the world of micro RC aircraft, and gives some insight into the kind of work that goes into making something like a 1:96 scale P-51 Mustang from scratch.
