RC Factory Bristol Scout Instruction Manual

Bristol Scout
Biulding instructions
Please read slowly and carefully!
Thank you for purchasing this kit. Scout was designed to be a slow and easy to fly plane but
still highly maneuverable and fun to fly.
Please refer to the Diagram Sheet while building this model.
Note: Gluing Depron – there are several different types of glue available. One of them is
foam friendly (“styro”) CA (Cyano-acrylate). The CA is often used, admittedly making the
parts joint somewhat fragile. Our preferred option is contact glue - one brand tested to
satisfaction is foam UHU-Por. You have to apply the glue on both parts (one trick is to apply
more of it to one glued part and to “stamp” this part to the other one to transfer some of the
glue) and wait about 5 minutes, until the glue is almost dry (yet still a bit tacky), then stick the
parts firmly together. You have to be precise; once glued, the parts are very difficult to take
apart, such attempt sometimes resulting in damage to one or both of them.
Sometimes polyurethane glue is used where extra strength is required. One such brand is
Purex (available in the Czech republic; equivalents should not be difficult to find). Servos can
be also very well glued in by a hot glue.
Any new kind of glue should be always tested on a scrap piece of Depron… you never
know…
Note#2: To cut Depron, use a very sharp hobby knife (and a steel straight edge). Depron tends
to wear out the edge of the knife quite fast – change your blades often.
Note#3: To make the L bend on carbon rod use lighter or tip of soldering iron to heat up the
rod in one spot. If heated enough you should be able to bend the rod easily using pliers. Fix it
in required position with drop of CA glue in the corner, with CA kicker.
Ok, let’s start the building…
Step 1
Cut off all the parts of the fuselage. Glue bulkheads A together using contact glue (such as
UHU por). Then glue the motor box , containing 3 gray parts and glue it into the holes in A
bulkhead. Trim the end of fuselage side panels (using sand paper) to 1,5mm thickness, so
when glued together they will fit to the 3mm thick rudder.
Step 2
Glue all bulkheads to the one fuselage side panel, letter side heading forward. When the glue
is hardened, glue the second fuselage side panel. Don’t forget checking the geometry!
Step 3
Locate two 41cm long carbon rods and make L bends on one end. Now push carbon rods
through holes in the bulkheads, leaving the L bend in the end out of the fuselage.
Step 4

Close up bottom rear part of the fuselage and glue the front upper part of the fuselage. Trim
edges of the upper part to fit on side panels perfectly.
Step 5
Cut a bevel to all edges where elevator meets the stabilizer and rudder meets the stabilizer.
NOTE: Elevator control horn is in the LEFT control surface! Hinge the elevators to the
stabilizer using clear tape. Connect both halves of the elevator together with 3,5cm long
carbon rod. Glue this part rather a little bit more strongly, to make it extra rigid. Now you can
glue finished elevator to the fuselage.
Step 6
Bend the airfoil of the wing panels, for example by sliding them over the edge of the table. If
the airfoil matches the wing templates, you can glue wings together. Check the wing dihedral
using the template (one half will be flat on the table and wing tip of the other half should be in
the notch of the template). Glue the lower wing to the fuselage.
Step 7
Attach wings together with templates as shown on picture. Glue 10cm long carbon rods about
2cm deep into the fuselage (locate small notches on the side panels) and later to the upper
wing. Check out geometry of your plane rather twice before using glue! Don’t forget plywood
reinforcements of the wing (Nr.4).
Step 8
Move templates to the tips of the wings. Glue 12cm long carbon rods between wings. Again,
don’t forget reinforcements Nr. 4 and Nr. 6 on the upper front hole. Nr 6 should be oriented
so remaining space in the plywood ring is heading to the fuselage.
Step 9
Glue motor mount Nr 1, tail spur Nr 3 and control horns Nr 2. Rudder control horn must be on
the RIGHT side of the rudder.
Step 10
Glue together motor cowl. Start with the outer layer and than glue inner reinforcements. You
can round off the front of cowl using sand paper. Glue rudder stabilizer in place and hinge
rudder to the stabilizer and to the fuselage with tape.
Step 11
Glue servos into the fuselage. You can use adjustable stoppers or end the push rods with Z
bend made from piece of string. Use screws to mount the motor to the firewall and install
your ESC and receiver. After checking the function of your RC system, glue the landing gear
together.
Step 12
Glue wing diagonal struts between the upper wing and the bottom wing, than glue yellow and
orange reinforcements to the A bulkhead and glue motor cowl. Place the battery to set the
CoG to 35-40mm from the LE of the upper wing.
Before first flight set your elevator throws to 15-20° up and down, and rudder throws to the
maximum that the V cut in the elevator allows.

Flying
Slowly push the throttle stick forward and let the plane take off. You can trim elevator to fly
really slow for indoor, of quite fast for outdoor flying. Also you can challenge your friends to
fly race around two trees or to land on table tennis table. Wherever you’re going to fly, just
have fun and enjoy your new Bristol Scout!
