Does anyone have access to the drag polar for the Allegro? For those who don't know, that is the graphical curve that illustrates the total drag of the aircraft on the vertical Y-axis and the airspeed on the horizontal X-axis. A related question: does anyone know the Vx and Vy airspeeds for the Allegro? I don't recall seeing these numbers in the operators manual but I've heard that 70 mph (61 knots) is Vy, but our Allegro gets a better rate of climb solo at around 75-80 mph IAS (about ~72 CAS). Since Vy decreases with weight Vy solo should be lower than Vy at MTOW, which is what most manual use for the V speeds.

The reason behind the questions is that I want to try to see if I can find some thermals tomorrow and get the Allegro to climb at idle power in a strong updraft and stay in the updraft. In other words I want to see if the Allegro can be soared a bit. The minimum sink rate speed would be helpful for this as well.
