Default Speed Astir flap speeds

Hi Guys,

One of our club members has just bought a beautiful Speed Astir.

Does anyone have an idea of speed to fly flap settings or did Dick Johnson ever do a test on one. Most of the other flapped gliders have some sort of recommendations for cruise vs climb

Check to see if the Grosskinsky ring is available for the Speed Astir at Wings & Wheels (or Bells & Whistles for gliders)

I owned a Speed Astir II for many years. N162SS
You actually control cruising airspeed with the flaps.
You trim the plane to fly at 55 knots at 0 flaps.
Then to go fast, dial in negative flaps.
To go slow, dial in positive flaps.

Be warned, if the ship does not have dimple tape or zig-zag strips on the wings it can have a very sharp stall when thermalling at slow airspeeds.

Other than that it was a sweetheart.

In the Speed Astir I flew back in Germany the flap handle was connected to a pointer in the airspeed indicator. Changing flaps let you read the associated best airspeed for that setting. Of course the ship also accelerated - slowed up nicely with moving flaps. Like DrG said: no trim changes needed.
