I am waiting for decent weather to do some flight testing using the Eagle Trees V2 datalogger.
My objective is to improve power-train selection methods for electric-powered scale models; to corelate flight performance with easily-made ground-run measurements.
------------------------------------------------------------------------
For example. We know the model's wing loading: what should the pitch-speed be on ground-test? [Might be not quite that simple]
--------------------------------------------------------------------------
Each flight will follow a sequence of "steady phases" designed to produce a lot of usable data in a few minutes of flight time.
Phases will include ; fast and slow climbs, f&s level flight and f&s glides. Phases will be of long-enough duration to establish steady conditions [about 10 seconds each].
Power-off stall will be checked.
