Kookie (oz1695)

About this Plan

Kookie. Towline and slope glider for single channel radio control. From Model Aircraft, April 1962.

Quote: "COOKIE was designed as a cheap-to-build, general purpose, R/C glider, for use for either slope soaring or towline operation. With an all-up weight of 20 oz, and CG at 55 per cent (standard trim) the model will average 3 min 40 sec of a 300 ft towline on a calm day and one flight of 25 min 18 sec was achieved off the local hill in a 10 mph wind.

Construction is conventional; the fuselage is designed around the Unitone receiver and Conquest escapement and, although it is of small cross section, there is plenty of space for the R/C gear.

Start by cutting out the fuselage sides and chamfer the sides at the joint; cut slots for formers F1 and F2 (making sure that they are not both cut for the same side!). Glue the sides together at the joint (over the plan side view) and carefully match them up. When the sides are dry, add the 1/8 corner longerons, bend the tow-hook and sew it securely to the 3/16 hard fuselage bottom..."
