By: Ralph Tarver - 10/10/09

John cooks a mean flapjack! And those sausage!

Those of you who missed the breakfast this morning also missed a lot of cholesterol . Twas good.

Great flying afterward. Nice winds & weather.

Thanks to everyone who was able to be here and pitch in.

All aircraft up and flying, training and fun flying.

We are now in the process of purchasing the single everyone wants.

We have a deposit on Grob Astir Standard.

It’s time to invest those excess funds in your club. Great return on your money and help our growth.

Flying tomorrow. Come on out. RT…

From Wikipedia:

The G-102 Astir is a single seat glassfibre Standard Class sailplane, designed by Burkhart Grob and built by Grob. It was the first Grob-designed sailplane, with the first flight in December 1974. (Grob had previously built the Schempp-Hirth Standard Cirrus under licence.)

The Astir CS [Club Standard] is of composite (fiberglass/resin) construction, has a large wing area, a T-tail and water ballast tanks in its wings. The large wing area gives good low speed handling characteristics but rather poor high speed performance compared to other Standard class gliders. In early versions some of the fuselage frame was wood, but this was replaced with a light alloy casting which sometimes cracks after heavy landings. The tail dolly is unusual by being plugged into a vertical hole.

A slightly improved standard-class version, the CS 77, was introduced in 1977. It has a different rudder profile and a slimmer fuselage similar to that of the Speed Astir. The Standard II and Standard III versions followed in the early 1980s, reverting to the higher profile fuselage and with a reduced empty weight and an increased payload. The above specifications are given for the Standard III.

The Astir CS Jeans was similar to the CS 77, but had a fixed main-wheel ahead of its center of gravity, and a tailskid. Its cockpit was fitted in blue denim. Later versions were the Club II and the Club III which also had fixed gear, but the Club III had a tailwheel.

The numbers built of each type were: 536 CS, 244 CS 77, 248 CS Jeans, 61 Club/Standard Astir II and 152 Club/Standard Astir III. A flapped version called the G104 Speed Astir was also produced.

One Astir (now residing at the Steven F. Udvar-Hazy Center), flown by Robert Harris, broke the world absolute altitude record at 49,009 ft (14,938 m) on 17 February 1986. This record lasted until 2006 [1].
