Greetings and congratulations on your purchase of the Extreme Flight RC 69 inch Turbo
Raven EXP! This revolutionary new airframe designed by our good friend Cody Wojcik
is insanely capable, precise, and pure feeling on just a 6S power system. This aircraft is
based on the short-lived full scale Turbo Raven piloted by Wayne Handley, which was
initially based on the Giles G-202 with extensive use of composites, and was one of the only
full scale aerobatic planes with a greater than one to one thrust to weight ratio. It was
capable of full 3D flight including flying straight out of flat spins, torque rolls and stop
and start vertical up lines.
With carefully analyzed moments and areas and a CFD analyzed airfoil, the Turbo Raven
EXP was designed from the outset to perform best at an extremely low wing loading that
would make more traditional designs feel sloppy, floaty, and imprecise. Its narrow
fuselage reduces drag and keeps the ailerons in the prop blast for maximum control at
near zero airspeed. Knife-edge requires no mixing and pitch response is as smooth as a
pattern plane and as powerful as an Edge when you yank on the stick. Huge,
counterbalanced ailerons mean the roll rate is fast but extremely predictable and
consistent, and it makes rifle rolls easier than any other airplane on the market. The clean
design also makes the Turbo Raven shockingly comfortable in the wind!
Paired with modern super torque mini servos such as the MKS HV9767 or Savox SV-
1260, DualSky G1500.5 and 17x6 prop (the Torque 4016T-500 and 16x7 will also work
well), and a 6S 3700-4500 battery, the Turbo Raven offers unprecedented performance in
an extremely affordable and convenient package.

Tips for Success:
1. Before starting assembly, take a few minutes to read the entire instruction manual to
familiarize yourself with the assembly process.
2. Please take a few minutes and go over all the seams on the aircraft with a covering iron
on a medium heat setting.
3. Apply a couple drops of CA to high stress areas such as anti-rotation pins, landing gear
mounts, servo trays and motor box joints .
4. When applying decals, first clean the area where the decal will be applied with alcohol.
Mist the area lightly with Windex or Rapid Tack before applying the decal which will
allow you to properly position it, then use a rubber squeegee to push all of the liquid from
under the decal. This will result in very few air pockets trapped under the decal.
5. Take the time to properly balance and trim your aircraft and set up rates and
exponential values. Your flying experience will be greatly enhanced by doing this.
The Ultracote colors used on the Turbo Raven are as follows:
True Red #HANU866, Pearl Dark Yellow #HANU843, Midnight Blue #HANU885, White
#HANU870 and Transparent Blue #HANU954

Let's begin!
1. Locate the 2 wing panels with ailerons as well as the 2 G10 aileron control horns and base plates.
Remove the aileron and pull the hinges from the wing and aileron. Use Pacer Formula 560 Canopy Glue
to secure the hinges. This glue works very well in this application and cleans up easily with water. Apply
the glue to both the hinge holes and the hinges themselves and push the surfaces together leaving a
minimal gap between them. Use masking tape to keep the aileron in position while the glue sets. Wipe
away any excess glue with a damp paper towel.

2. Remove the covering over the slot for the aileron horn on the bottom of the aileron with a sharp hobby
blade. Make sure you are doing this on the bottom of the aileron! Insert the horn into the base plate and
into the slot in the aileron. Use a fine tipped felt marker to trace the base plate. Use a sharp blade to
remove the covering under the base plate. Scuff the control horn's gluing surface with sandpaper and
glue the horn and baseplate in place with medium CA.
3. Attach a 6" servo extension to your aileron servo and secure with an Extreme Flight Servo Safety Clip
or a piece of heat shrink tubing. Secure the servo into the slot with the output spline facing the leading
edge of the wing. Assemble and install the aileron linkage as shown in the picture using the provided
2mm hardware. Please note the ball link and pushrod are mounted to the bottom of the servo arm.

4. Locate the fuselage, carbon fiber main gear, wheel pants, fairings, wheels, axles and related hardware
for mounting the landing gear. Use the provided mounting hardware to secure the main gear to the
fuselage. Be sure to apply blue thread lock to the bolts before inserting into the gear and pre-installed
blind nuts.
5. Secure the landing gear cover to the carbon gear with a couple beads of white glue or silicon glue and
tape in place until the glue sets.

6. Glue the landing gear fairings into place against the fuselage side with silicon glue or medium CA
applied to the carbon gear leg.
7. Secure the provided axles to the landing gear with a washer and nylon insert lock nut.
