Open Source Airframe

My project started

Well today placed the order for a few bits n bobs with a widget or two thrown in :) the Ardupilot and accessories was ordered. This includes the 900Mhz Xbee Pro, only the FMA sensors to order still as they are back in stock on the 15th :D

The new DSX9 2.4Ghz and the EasyStar with brushless upgrade can now be put to good use, well as soon as the thing is built....

Today was radio day :) JR DSX9 it was, easy to change modes, easy to program and 2.4Ghz. More than enough radio to grow into over time, good local support and the price was reasonable.

Now the build can start, well that is after the hobby room is prepared :)
