The tapered nose portion 74 of the fuselage 12 deforms easily and presents a relatively soft impact area which absorbs the energy of impact and then returns to its original shape. Similarly the wing 12 and the rudder 66 deform during impact and then return to their original shape leaving the toy foam glider 10 undamaged. The relatively high coefficient of friction between the foam material of the fuselage 12 and the wing 42 and rudder 66 portions combined with the corners 60, 62, 76 and 78 on the wing 42 and the projecting tab 70 on the rudder 66 reduces the possibility of the wing 42 or the rudder 66 becoming dislodged during use.
In a preferred embodiment of the invention, the fuselage 12 of the toy foam glider 10 is made of a relatively low density open cell foam, such as polyurethane foam and the wing 42 and the rudder 68 are made of a closed cell elastomeric foam having a somewhat greater density then the foam used for the fuselage. The relatively low density of the foam used for the fuselage 12 makes possible the use of a thickness of foam which permits a more realistic representation of the thickness of an aircraft fuselage than is possible using conventional toy glider materials such as balsa wood. The relatively low stiffness and the resiliency of the foam material permits the use of the toy foam glider 10 indoors without the danger of damage to walls or furniture, or to the toy foam glider 10 itself, due to impact during collision.
The toy foam glider 10 also includes a rudder 66 which is inserted in the rudder slot 24 in the direction of the arrow 68 in FIG. 2. The rudder 66 has a projecting tab 70 which rests on the surface 72 of the fuselage 12, as shown in FIG. 3, thus locating the rudder 66 in the vertical direction.
The wing 42 of the toy foam glider 10 has a tapered leading edge 44 and a straight trailing edge 46 resulting in a delta wing configuration. The central portion 48 of the leading edge 44 and the central portion 50 of the trailing edge 46 have respective notched portions 52 and 54, as shown in FIG. 2. The distance between edge 56 of notch 52 and edge 58 of notch 54 corresponds to the length of the wing slot 16 and the width of the notch 52 and notch 54 corresponds to the width of the fuselage 12. During installation of the wing 42, the material of the fuselage 12 is stretched over the corners 60 and 62 and of the wing 42 when the wing 42 is inserted into the wing slot 16 in the direction of the arrow 64 in FIG. 2. The material of the fuselage 12 and the wing 42 return to shape after the installation of the wing 42, thus retaining the wing 42 in place.

I suspect you know there are more than a few threads dedicated to converting toy foam gliders to RC, with or without a motor. One of the more popular toy foam gliders is the Titan by Air Hogs.
