Cover the bottom of a fuselage first. When doing compound curves, as on the nose shown here, be sure to leave extra
material around that area. Grip the covering and apply heat. As the covering becomes pliable pull the covering around the
curve. Work slowly and cover small sections at a time.
10.
Trim off excess and seal edges. Repeat this procedure on the sides. Allow about 1/8" to 1/4" overlap for a fuel-proof seam.
11.
Cover the top and seal down all edges.
12.
Remove covering from areas to be glued. There must be wood-to-wood contact in the glue joints. Strips of covering may be
applied over seams to seal them.
RADIO INSTALLATION
The following information can be used as a guideline for mounting your radio in the RISER. The methods described below
are fairly standardized and should work well with any system, although you should read and follow the manufacturer's
instructions supplied with your radio.
Mounting Servos In The Fuselage
The rudder and elevator servos should be mounted side-by-side in the wing
opening so that the output arms are lined up with the ends of the nylon
pushrods. Screw the servos to hardwood mounting rails that are epoxied across
the inside of the fuselage. We recommend that the hardwood mounting rails be
made of 3/16"x3/8" spruce, pine, or basswood. Do not make the rails out of
balsa! Glue scrap pieces of balsa to the fuselage sides around the ends of the
mounting rails so that they can never come loose in flight. If you plan to use the
optional spoilers, the third servo should be mounted forward of the flight control
servos.
You can also use foam servo mounting tape and stick the servos to the fuselage sides. For the best bond to the fuselage,
coat the balsa where the servo will be seated with a thin film of epoxy. Although this method is quick and easy, it is
generally accepted that the servo rail method of servo mounting is more secure in the long run.
