| The geometry (monkey Motion) was calculated by the Helicopter guys (which I am definitely not!) and I began to CAD up all the parts, then fabricate all the parts (minus the gears and motor), assemble, and test this thing. It fly successfully in the simulated Mars atmosphere in JPL's HUGE vacuum chamber the test all the Earth orbit satellites in. Just nine little "Hops" but it actually did better that the 4 channel vehicle. Here's a JPL video. I made most of the Rail vehicle, and my two channel is at 1:57ish. http://www.jpl.nasa.gov/video/details.php?id=1355e. |

| This is something I did for work last year. JPL came to Aerovirnment (where I work) to test the feasibility of flying a rotor-craft on Mars. After a successful proof with a Rail-Guided model in a very large vacuum chamber to simulate Mars atmosphere at JPL, we were asked for a Free-Flight model to further prove the concept. We decided that some control would be needed so a 2 channel (throttle and yaw)) would suffice. Atter further consideration a 4 axis craft was decided on though the Boss Man still wanted the 2 channel for backup. Hence I was told I was on my own to develop the 2 channel vehicle. |

| After a couple lunch-time builds and after hours, the tail feathers are done and the wing is almost ready for shaping. Blazing florescent lighting doesn't make for very dramatic lighting. The laser cutting on this model is superb. |

| Like this. The other sections will require additional bracing. |

| This framework is made of hard 3/32" stringers and will support the 1/16" sheeting. A 1/16" stringer (red) is glued 1/16" below the top and bottom edges of the wing root rib to support the sheeting. |
