Status Update

Today the Electronic mounting has been almost finished. The Picture shows the electronic bay with assembled main board, battery, servos and connection tubing for barometer and Pitot tube.

The battery is a single cell 5 Ah rated Li-Po from China. A measurement shows up a capacity of more than 6 Ah on 600 mA discharge current (That's the consumption of the plane electronics including GPS and Transceiver but without Servos). A circuit using the MAX1708 is used to step-up the cell voltage to 5 V.
