INTRODUCTION
Congratulations and thank you for the purchase of great product! It is our sole desire for you to enjoy
the quality workmanship and performance of any of our helicopters. We believe we have the latest
designs and technology incorporated into our model helicopters. Our CNC parts are produced using
the best high density materials & anodized using material hardening finishes with the tightest of
tolerances. Our new helicopters feature the latest advances in R/C helicopter design. The simple
and mechanically superior EMS design (also known as CCPM) ensures a helicopter that will be more
responsive and more stable than any other R/C helicopter you have ever flown. In the Gasser, three
servos are attached in a push-pull system ensuring precise control. Frames are specially designed
with “floating system” engine mounting. This new design eliminates most engine vibrations. The
Gasser kit comes in 2 versions: Sport with G-10 composite frames and Pro with carbon fiber composite
frames. Each frame is 3mm thick offering the utmost in rigidity and strength. This helicopter features a
separately purchased kit allowing the owner to change the helicopter from a belt-powered tail rotor
to a torque-tube-drive system. The owner may also purchase the helicopter initially with the torque-
tube-drive system. Along with great products, our staffs are RC guys that fly and have hands on
experience with total manufacturing & testing of our helicopters. In addition, we stand behind all our
products 100% with satisfaction guaranteed. Our kits will be shipped 100% complete and we can
assure you that once you fly your helicopter you will love it.
We believe you hold in your hands one of the best helicopters manufactured in the world today. The
brand new Little Dominator is the newest version of our Big 26CC Gas Dominator. It has thicker 2.0MM
frames and is a powerful machine. This baby delivers amazing power smoothly throughout the entire
range of its gas engine. Its functions are very responsive and stable. The Little Dominator Pro version
features a fully machined dual-spindle head, metal tail rotor, metal grips, carbon fiber frames, bigger
carbon rudder push rod, carbon linkage rods, and carbon fiber boom supports. The Little Dominator
Sport version features a G10 fiberglass frame, fully machined metal head, carbon boom supports,
carbon rudder push rod, and molded tail blade grips. Our helicopters are carefully designed and
tested, and manufactured of the highest quality materials available.
In a short time, you can be flying.
We ask that you please read the entire manual before starting the construction of the Little
Dominator, and if you have any questions our technical support staff can be reached at

OTHER REQUIREMENTS
Radios:
Any radio that supports EMS/CCPM Mixing will work fine.
Note: Please consult the instruction for your Gyro for setting the overall travel and
limits to ensure proper operation and travel of Tail Pitch Slider.
Servos:
Any premium, sport, or high quality servo will offer acceptable performance.
However, because servos operate all critical functions of the helicopter, they can be the
single most important component that contributes to proper function of the helicopter. Due
to the nature of EMS collective, we suggest the use of digital servos to enhance and ensure
matched servo timing without servo interaction.
Loctite Warning (CRITICAL):
This is a general warning about the use of Loctite and
its importance. Loctite must be used anywhere that a metal
fastener i.e. (M2, M3, M4 Cap Head Bolts, Set Screws etc.) is
threaded into a metal part i.e. (Bearing Blocks, Cross-members,
etc.). Failure to use Loctite can result in loosening of critical
operating components, loss of control of the model, and can
lead to a crash.

PART LIST
•In your kit, parts are bagged according to each major assembly and are labeled “Bag
1, Bag 2, etc.” You will note that the heading for each assembly indicates which bag correlates with
each assembly.
•For a good installation, only open up the bags that you need for particular assembly.
•Please check the parts in that bag against the parts list shown for each assembly as well
as each subassembly to make sure there are no missing parts.
•Small parts such as nuts and bolts can be put into containers or trays to prevent losing
parts.
•Part No. with ***** means that part is not included in the kit.
•The colors of drawings and appearances of parts in this manual may look different from

Step 1
Read the entire manual to become familiar with the layout of the machine and
these instructions. Verify the parts in each bag with the Pick list that came with your kit. Be
careful to set up a good work area so parts do not get lost and always reseal the bags
when you are finished working or have taken out the parts you plan to install in the current
work session.
Secure and organize the tools you need at your work area so they are close by
when you need them, you will thank yourself later. Check the assembly table for each
section to find the tools and parts you will need before you start.
It is easiest to build the main assembly in the order given here although separate
sub assemblies such as the head, washout, swashplate, and tail assemblies can be built at
any time and set aside for when you need them for the main assembly. Shown below is the
finished Lower frame assembly with engine installed.
Left side: As if
you were sitting
in the pilot’s seat.
Optional Finishing Caps

Step 2
Check and layout the parts for the lower frame assembly. The table below shows
the parts and tools necessary for this work session. Building this part first will give you a strong
base for the entire assembly. It will help to keep your hands free eliminating the need for a
third hand.

Step 3
Attach the gas tank assemblies to the right lower frame with two 3 x
8mm SHCS as shown below. Be sure to face them away from each other as it
will make the area that touches the tank larger and more stable. Use a frame
angle or any flat surface to press against the bottom of the crossmembers
making them aligned parallel to each other as you tighten them. Now the
frame piece will stand up while you work on it. Next attach the frame angle
through the first three holes of the frame angle and the last three holes of the
frame. Use 3 x 8mmSHCS for the nuts and a 3mm locknut as shown below.
