I have posted some data obtained from test flights. The graph's have been made using MS-Excel.

Graph showing Calibrated airspeed (Average GPS groundspeed in opposite directions at 2000') vs. Indicated airspeed

Graph showing rate of climb vs. IAS. Climb have been timed from 500' - 1500' after takeoff. (around half fuel, and one person onboard)

Graph showing climb angle vs. IAS. Obtained from same data as graph above. CAS data used for angle calculation.

Graph showing rate of descend vs. IAS. I have timed 1000' descend (usually 2500 to 1500) at different airspeeds.

Graph showing glide distance vs. IAS. Obtained from same data as graph above. CAS data used for distance calculation.
