To ensure many hours of trouble free operation of your new Whirl
Wind propeller, please read and follow the operation and
maintenance recommendations in this manual.
The Whirl Wind 200G/210G Series propellers are composite blade
ground-adjustable pitch propellers. Unlike conventional ground
adjustable propellers, the blade pitch is easily adjustable in ½°
increments via a single adjustment screw. The full range adjustment
of the 200G is 10° to 26° and the full range adjustment of the 210G is
9° to 25°.
* Refer to the original propeller data sheet for initial factory low pitch
setting.
Whirl Wind propellers are experimental class and are not
subject to any Federal Aviation Administration regulations. The
operator acknowledges that these are experimental propellers
and agrees to assume all risk in operating them on an
experimental aircraft or any other machine. Any and all
information in the owner’s manual, service letters and other
documentation are suggestions only and may not apply to an
operator’s specific application.

Section 1: Introduction
2.1 Description
The 200G/210G Series propeller has been designed to
maximize the performance of your airplane! This propeller
delivers exceptional performance for the modern day utility
aircraft. The exceptional performance is derived from
advanced aerodynamic engineering techniques including
computerized airfoil modeling.
Whirl Wind has made significant developments in the
construction of the carbon composite propeller blades
ensuring a strong, light and durable propeller system. The
blade twist has been optimized for maximum performance
and the wide chord allows for more low-speed thrust and
braking. The 200G/210G propeller’s pitch is ground
adjustable.

Section 2: Overview

2.3 Construction
The 200G/210G Series propeller blades are constructed
from advanced thermoset composite materials. Each blade
is equipped with a nickel leading edge erosion shield to
protect the blade leading edge from rain and debris damage.
The 200G/210G Series hub is CNC machined from certified
aerospace aluminum alloy, which is then shot peened and
anodized. The hub blade sockets are equipped with ball
bearings to ensure smooth pitch change of the blades
throughout the life of the propeller system. This propeller
can be flown in rain and off unimproved airstrips.
2.4 Configuration
The 200G/210G uses a threaded “piston” whose position is
moved fore and aft when the adjustment screw is turned.
The piston is connected to the blade bases via pitch links.
The fore and aft movement of the piston rotates the blades
in the hub, changing their angle of attack (pitch).
Mechanical stops for high and low pitch limit the pitch
change travel; for the 200G minimum fine pitch of 10° and
maximum coarse pitch of 26°, for the 210G minimum fine
pitch of 9° and a maximum coarse pitch of 25°.
* Refer to the original propeller data sheet for initial factory
low pitch setting.
Do not change the pitch adjustment screw until the
propeller is installed on the airplane and the pitch scale
and indicator are applied to the blade ferrule and the
spinner dome (see Section 5 below).
2-2
Each Whirl Wind propeller system has a factory designated model
number and serial number, which will identify the hub and propeller
serial number. The propeller system blades will have individual
serial numbers etched on the ferrule of each blade near the root end.
All Serial numbers can be found on the owner’s data sheet.
Example: 200G-108
Series and Hub Style 200G/210G
Propeller Serial Number 108

4.1 ropeller and Spinner Installation
WARNING! DO NOT OPERATE THE ENGINE /
PROPELLER WITH ONLY THE SPINNER FILL-IN
PIECES INSTALLED!
IF THE ENGINE AND PROPELLER ARE TO BE RUN WITHOUT
THE SPINNER DOME INSTALLED IT IS IMPARATIVE THAT THE
FILL-IN PIECES ALSO BE REMOVED. The centrifugal force will
damage or destroy the fill-in pieces without the support of the spinner
dome. (The engine and propeller can be operated with only the
spinner rear bulkhead installed.)
* For safety reasons always turn the propeller opposite
of the usual direction of rotation.
STATIC (MOUNT)
POSITION
STARTING
(MAGSNAP)
POSITION
Propeller Clocking: The historical installation position of a
two blade propeller is to place the upper blade in the 10
o’clock position as shown above.
The 10 o’clock position allows for the easiest hand / prop
starting of the engine by pulling the left blade down from the
10 o’clock position to the approximate 7 o’clock position
where the magneto snaps and the ignition fires.

Section 4: Installation Instructions
Step 1: Before beginning installation of the 200G/210G Series
propeller system inspect the O-Ring located in the propeller hub
flange and make sure the O-Ring is in good condition. (Note: The
hub O-ring is not required for the non-hydraulic ground adjustable
propellers.)
For Two Piece Rear Spinner Bulkhead Installation:
Step 2: Using the supplied AN3 bolts and nuts, install the (2)
temporary spinner installation plates as detailed below. The
installation plates are provided to maintain the proper spacing of the
(2) spinner mounting plates when the propeller mounting studs are
tightened.
4-2

For One Piece Rear Spinner Bulkhead Installation:
Step 2: Note the factory position of the spinner rear bulkhead in the
spinner dome in relation to the blade cutouts to determine its
required position on the propeller hub. The spinner and spinner rear
bulkhead have been number coordinated to match the blade cutout
openings. Using the supplied AN3 bolts and nuts install the spinner
rear bulkhead to the spinner mounting plates. The supplied flat
washers are to be installed on the fiberglass side. The bulkhead is
to be installed on the aft side of the mounting plates. (The standard
200C 14” rear bulkhead is an exception; it is to be installed on the
forward side of the mounting plates. A slot is provided in the
bulkhead so it can be slipped over the mounting plates into its
forward position.) Tighten the bulkhead mounting hardware.
Step 3: If used, lightly lubricate the O-Ring with clean oil or O-Ring
lube and carefully install the propeller on the engine crankshaft by
tightening the (6) propeller bolts.
Warning: To avoid severe damage to the hub, when tightening
the propeller bolts insure that the face of the prop hub is kept
parallel with the face of the flywheel. In most cases this will
require tightening the propeller bolts a little at a time in an
alternating pattern.
Step 4: Torque and safety wire the propeller hub bolts. Refer to data
sheet for torque (dry, non-lubricated) values (65 ft-lbs for ½”
hardware or 47 ft-lbs for 7/16” hardware). Safety wire the prop bolts
in pairs with 0.32” stainless safety wire after installation.
** Installation with a one piece rear bulkhead is complete. Proceed to
Section 4.2 **
For Two Piece Rear Bulkhead Installation:
Step 5: Remove the (2) spinner installation plates. Save them for
future use.
Step 6: Note the factory position of the spinner rear bulkhead in the
spinner dome in relation to the blade cutouts to determine its
required position on the propeller hub. The spinner and spinner rear
bulkhead have been number coordinated to match the blade cutout
openings. Using the supplied AN3 bolts and nuts install the spinner
rear bulkhead to the spinner mounting plates. The supplied flat
washers are to be installed on the fiberglass side. The bulkhead is
to be installed on the aft side of the mounting plates. Tighten the
bulkhead mounting hardware.
4-3
4.2 Spinner Dome Installation
Install the spinner dome onto the propeller hub and rear
bulkhead. The spinner and spinner rear bulkhead have been
number coordinated to match the blade cutout openings.
The spinner dome has a forward bulkhead with a flanged hole
that must engage the cylinder (cap) on the front of the
propeller hub. The fit of the forward bulkhead to the cylinder is
to be snug BUT NOT SO TIGHT that excessive force is
required to push it on. If the fit is too tight, sand the inside of
the forward bulkhead flange. If the fit is too loose, apply the
provided Teflon tape to the cylinder. In some cases a
combination of these processes will be required to obtain the
proper fit.
Fasten the spinner dome and blade cutouts to the rear
bulkhead using the supplied screws and nylon washers.
IMPORTANT: Periodically verify that the spinner screws
are tight during the first few hours of operation.

WARNING: Operation of this propeller over maximum RPM
is strictly prohibited and will result in a catastrophic
structural failure of the propeller system. Any type of
structural failure may result in death or severe bodily
injury. Refer to your propeller data sheet for Maximum
RPM.
USE EXTREME CAUTION when performing ground run-up. Engine
and propeller manufacturers typically do NOT recommend high
engine power settings on the ground because it can result in
excessive engine temperatures and propeller blade foreign object
damage.
5.1 erformance Considerations
The design objective of the Whirl Wind 200G/210G Ground
Adjustable Propeller System was to provide the pilot with a
propeller that could be quickly and easily adjusted for either
maximum take off performance or endurance for long cruise
operations.
It is important to always remember that there is a trade-off for
these values: Increased endurance (lower fuel burn) can only
be obtained at the expense of take off performance. A
decrease in performance (due to a coarser / greater blade
pitch angle) will necessitate a longer take off roll and distance
to clear obstacles in the climb-out path.
The chart below shows the general relationship of the three
variables; 1. Blade pitch angle, 2. Endurance (fuel burn) and
3. Take off roll (performance).

Figure 5-1
This chart is only a guide and does not apply to any specific
airframe and power plant configuration! The actual values will
vary, and in some cases greatly, for each specific airplane.
Whirl Wind Aviation strongly suggests that each airplane be tested
with a number of different blade pitch angles and the resultant take
off roll and fuel burn figures be recorded below for future reference.
Be sure to have adequate runway length and a clear departure
path before experimenting with coarse blade pitch angles!

5.2 First Time Operation
Do not change the pitch adjustment screw until the
propeller is installed on the airplane and the pitch scale
and indicator are installed on the blade ferrule and the
spinner dome (see Figures 5-2 and 5-3 below).
Per Figure 5-2, place the pitch indicator arrow label on the
spinner dome indicating the factory low pitch setting.
* Refer to the original propeller data sheet for initial factory
low pitch setting.
5.3 First Run-Up
The primary objective of the first run-up series is to
establish baseline values for engine RPM at full power
(maximum throttle with various blade pitch angles.
CAUTION! As stated above, many airplane and propeller
manufacturers do not recommend high power run-ups due to
the possibility of debris damage. If a high engine speeds are
required be sure to perform the run up on a clean surface
and you are in a safe, unobstructed area.
Follow your airplane’s manual and perform an engine run-up
using the factory set low pitch setting.
The RPM restrictions from the engine and propeller
manufacturers must be strictly observed.
The initial factory set low pitch setting (refer to original
propeller data sheet) may be too fine for your engine and
could lead to an engine over speed. Advance the throttle
slowly to be sure that an over speed does not occur!
If the engine can not reach 2,250 to 2,300 RPM at full
throttle the factory setting is too coarse. DECREASE the
blade pitch angle by ½° increments following the propeller
pitch changing instructions below. For each ½° decrease of
blade pitch angle repeat the run up to full throttle until the
correct pitch setting is found that maintains 2,250 to 2,300
RPM at full power.
5-3
If the engine wants to exceed 2,250 to 2,300 RPM at full
throttle the factory setting is too fine. INCREASE the blade pitch
angle by ½° increments following the propeller pitch changing
instructions below. For each ½° increase of blade pitch angle
repeat the run up to full throttle until the correct pitch setting is
found that maintains 2,250 to 2,300 RPM at full power.
Note: The procedure above is recommended to establish
baseline settings of blade pitch and resultant engine speeds
(RPM) at full power. 2,250 RPM is only an example – a
conservative RPM for safety and prevention of engine over
speed. The most appropriate baseline settings will vary for each
application. As this procedure is completed record the static
RPM in the table on page 5-2 for future reference.
5.4 Inspection After First Run-Up
1. Inspect the propeller system blades and spinner for any
nicks, cracks, or chips.
2. Inspect each aluminum blade ferrule and blade intersection
(located at the root end of blade where the silicone sealant is
visible) for movement and/or signs of chafing. There should
be no movement between the aluminum ferrule and the
blade. Notify Whirl Wind Aviation immediately if movement
is detected.
3. Gently shake each propeller blade to feel for blade
movement in the hub. Blade shake movement is allowed up
to 1/8 inch measured from the tip. Radial play of up to 2
degrees is acceptable. If the check shows values above
these tolerances contact Whirl Wind Aviation immediately.
Movement is only allowed between the aluminum blade
ferrule and the propeller hub – and not as described in point
#2 above.
4. Inspect the nickel leading edge erosion shield. The nickel
erosion shield should not be loose or have any cracks. Small
paint cracks parallel to and along the edge of the shield
where the nickel and paint meet are acceptable.
5. Check the spinner dome and the aft and forward bulkheads
for cracks of any kind or looseness.
Your Whirl Wind Propeller System has been statically balanced
at the factory. However, it is recommended to have the
engine/propeller dynamically balanced before the first flight.
5-4

Repeat the same inspection after balancing as for first run-
up. All engine RPM and power settings limitations must be
followed when operating the Whirl Wind 200G/210G Series
propeller. Refer to your Whirl Wind propeller data sheet for
propeller operation limitations.
5.5 Changing the ropeller itch
Step 1: Remove the plastic hole plug from the point of the
spinner dome.
Step 2: Using the provided 1/8” hex T-handle wrench inserted
through the hole in the spinner dome, back out the pitch lock
pin (counter-clockwise) approximately five (5) turns
(approximately 1/4”). See Figure 5-2.
Do not remove the lock pin from the cap. Complete
removal of the lock pin may lead to it getting lost.
Step 3: Using the provided 5/15” hex T-handle wrench
inserted through the hole in the spinner dome, turn the pitch
adjustment screw to increase or decrease the blade pitch to
the desired pitch setting referencing the pitch scale and
indicator labels. See Figure 5-2.
Turn the adjustment screw CLOCKWISE to DECREASE
(flatten) the blade pitch.
Turn the adjustment screw COUNTER-CLOCKWISE to
INCREASE (coarsen) the blade pitch.
There are (5) spring-loaded detent positions around the
circumference of the piston driver (see Figures 5-2 and 5-3).
As the pitch adjustment screw is turned listen for each “click”
of the detent indicator. Each detent position (click) is equal to
½° change of blade pitch angle.
Step 4: Using the provided 1/8” hex T-handle wrench tighten
the pitch lock pin (clockwise) until it is snug – do not over
tighten. See Figure 5-2.
Step 5: Reinstall the plastic hole plug in the point of the
spinner dome.
5-5
NOTE: Through testing on a variety of airframe and
engine configurations Whirl Wind Aviation has
determined that a blade pitch angle of 13.5° is a good
“all-around” setting that provides reasonable take off
and climb performance and decent cruise fuel
economy. Of course, all airplane configurations are different and it
will take some experimenting to determine which setting is optimum
for each airplane.

There is no special maintenance schedule for the Whirl Wind
propeller system beyond the usual inspections listed in Section 6 and
the teardown inspection schedule listed below. It is recommended
that the operator apply a high quality paste wax on glossy finish
blades at least once a month to aide in protection from the elements
- it is important that the blades are always sealed from outside
moisture. Automotive materials such as Acryluathane paint and
Epoxy resin can be used to repair most small scratches and chips.
7.1 Teardown Inspection Schedule
Refer to original propeller data sheet for recommended
teardown inspection schedule. If the original data sheet
cannot be found, please contact Whirl Wind Aviation directly
to confirm the recommend schedule for your propeller.
7.2 Use of ropeller Log Book
Proper maintenance of this logbook is the owners
responsibility. It is an important record designed for the
owners information and protection.
If the propeller is sold or installed on another aircraft, the
logbook should be transferred with the propeller. New owner
information should be registered with Whirl Wind Aviation by
calling 440-275-1540.
It is recommended that maintenance release tags and work
orders be attached inside the back cover of this book. If a
copy of the work order is not available, the repair station and
work order numbers should be referenced in the logbook
entry.
