Instructions 

Introduction. 

The

Gentle Lady

sailplane was designed to be a gentle trainer for the beginning R/C modeler, yet to possess

competition capability in the hands of the experienced glider pilot. As a very efficient machine, she reacts quickly to rising air
( called lift, or thermals). To stay in the thermal, she can circle very tightly without falling off. The model has good penetration into
the wind and can really “cruise” when desired. Before starting to build, read through these instructions and familiarize yourself with
the plans. If a 6-1/2 ft. wing will not fit into your car, you will want to build the wing version with removable tips. 

The 

Gentle Lady 

can be flown a number of ways: hand tow, high-start, slope soar, or power. The simplest method is hand tow,

which resembles towing a kite into the air. High-start is a combination of elastic cord and tow line. When stretched, the high-start
will gently tow the model up to an altitude of several hundred feet from which a flight of three minutes or more in dead air ( no
Thermals) can be obtained. A variation of the high-start is the more expensive powered winch, popular with glider clubs. If you live
near unobstructed hills or ridges, slope soaring is easily possible, so long as you have a suitable landing area. Hand launching the
model off the upwind side of the slope, directly into the wind, will enable you, with practice, to soar back and forth along the slope
in the rising air for as long as the wind remains. Finally, the use of power is an excellent option, and this book and the plan show
typical installations. For the modeler who wishes to power fly the

Gentle Lady

at all times, nose mounting of engine is recom-

mended. Pod mounting has two advantages: the power pod assembly can be easily removed for flying the model as a pure glider,
and engine oils are less likely to dirty the fuselage.

Warning 

A radio-controlled model is not a toy. It is capable of causing serious bodily injury and property damage. It is the buyer’s responsi-

bility to build this kit correctly and to properly install the motor, radio, and all other equipment. The first test flights should be made
only with the assistance of an experienced R/C flyer. The model must always be operated and flown in accordance with the safety
standards of the Academy of Model Aeronautilcs. 

Per the Federal Communications Commission, you are required to use only those radio frequencies specified “for Model Aircraft.”
