Old log, 11/2012 to 12/2012

Got new frames. It's better except i had two small mistakes. lucky is the mistakes not enough block this process. Finally I can test flight my monster in tomorrow.

Third drawing fix and send to laser cnc. I got a great gift. The google sketchup is free CAD software. It's a wonderful meaning for me! because I from a country of always used pirate software. Thanks google and dxf_plup-in to help me export DXF, then i can finish this project and don't use pirate software. Hope it can save my soul a little.

The accident always full in the life. I plan use APM to control this monster. APM is a system of very powerful and easy to use, but his helicopter mode(ver. 2.7.3) had a few bug, tail can't control by joystick and can't save the servo position's param. Now MWC give me a big surprise, He can support helicopter mode too. Although MWC haven't too much function like APM, but basic helicopter flying control looks better than APM. It's just guess, need wait real flight testing.

So sad a day。 I got second frames after long time waiting. First cnc operator had mistake, lost some detail, and i had mistake again. So drawing must fix again. Just a good news, the test of electronic part was successful. Four servos use 6v 8a power, BEC and APM use 5v 2a power. They can work together.

Got new servo and send drawing to laser cnc.

I got great confidence from the monster rise up. I decide use better servo. Today, finished fix door and tooth size, re-design servo seat.

got the frames and first build. The doors size all was wrong!!!FML! Need fix it and laser cnc again... lucky have a good thing, thrust was enough, this heavy monster really can be fly. It can rise when throttle position at 55%.

send drawing to laser cnc, use 2mm composite laminate.

finish drawing design.
