Flight Test Log 7

================================================================================

Summary
-------

Tests of night flying, subscale, using blue LEDs as light source. Control
was marginally improved over previous night tests that used a yellow-green
lightstick. Lighting still needs work.

Also, a new LiPo battery was tested, which has a built-in charge protection
circuit. The battery seemed to work OK as far as I could tell.

   Test ID:  23
      Date:  2005/04/14 (Thu)
      Time:  20:40
      Wind:  Calm
   Vehicle:  SVC
     Scale:  41 %
      Mass:  236 g
  Location:  Pima West

Tested subscale SVC after dark with 4 high-intensity blue LEDs installed:



The vehicle was marginally easier to control than it was previously with
a yellow-green internal lightstick as a light source. Lighting still needs
work. Landing was good, no damage.

Except for its small size, the field is excellent, with a thick grass
surface.

This was also a test of a new flight battery:

                                Brand:  ElectriFly
                          Part number:  GPMP0810
                            Chemistry:  Lithium polymer
                             Capacity:  2590 C                 (720 mAh)
                      Number of cells:  2
                              Voltage:  7.4 VDC
                                 Mass:  39 g

The battery has separate connections for charge and discharge, and has a
built-in charge protection circuit.
