While many of these procedures are applicable to the T-1
and T-1 Mini jets as well, this guide is specific to the T-3 With Electric Gear Set.
This guide does not cover radio setup, programming or turbine operation. You will
need to refer to the documentation provided with those systems for information on
proper setup and operation.

Tips for Success:
•Don’t rush! Allow plenty of time for your build. Take your time, enjoy it, and do it right.
•Don’t be afraid to ask questions! In addition to this document there are several build threads on RC Universe
where you can get input and assistance with your build:
•Complete the latter part of your build on a CG stand…when you’re down to the components that can relocate in
order to adjust CG.
•After your build is complete, have another turbine operator/pilot review your build. A fresh set of THIS s is a
good sanity check.

The kit will come very well packed.
Carefully remove all the parts from the
bubble wrap that they are encased in. Do
not use a knife or razor as you can
inadvertently cut through the packaging
and damage the finish of the parts. Peel or
use scissors to carefully cut and remove
the tape.
Inspect all parts for any shipping damage
and test fit. Check all packaging, parts and
components. It’s good to organize and
identify hardware and components before
you start the build.
You can use some of the packaging
material to place your air-frame parts on to
keep from damaging or scratching during
your build.
Sometimes the painting process results in a
rough edge that might cause binding. This
is easily resolved by using a common emery
board to gently smooth the
underside/inside the flight surface and the
top/outside on the control surface. Use
tape to protect the painted areas on
control surfaces. Go slow and don’t be too
aggressive with the file to avoid removing
too much material.

AFT Fuselage Zip Tie Mounts & Harness
Installation.
For this process we use self-adhesive Zip
Tie mounts and small Zip Ties to secure the
wire harness in place. Use the photos for
reference on where to install the Zip Tie
mounts and harness. Note: Start wire
harness installation from the AFT forward
leaving at least 2” of wire out of the
fuselage at the connection points for the
stab and rudder.
Once wires are secure use CA or Hysol on
edges of Zip Tie mounts for permanent
adhesion.
Make sure to have no sagging wires. You
can use aluminum tape around
Midbody Fuselage Zip Tie Mount
Installation.
For this process we used the self-adhesive
Zip Tie mounts. Use photos for reference
on where to install the Zip Tie mounts. Use
CA or Hysol on edges of Zip Tie mounts for
permanent adhesion.

Midbody & AFT Fuselage Assembly.
Make sure the bell mouth is secure and
tight to the pipe. If you plan to use the
PRCJ 36” Smoke Stick, pre-install now at
the top center of the pipe and slide pipe
into AFT Fuselage. Pull your wires through
at the top access area, line up the
AFT/Midbody sections, apply Blue Medium
Thread Locker and install top bolt with the
provided wrench, (Lightly Tighten Bolt)
then loose install the remaining 5 bolts
with Medium Thread Locker. During
tightening, ensure proper alignment of the
AFT and Midbody sections before fully
tightening down the bolts
Securing Pipe and Smoke Tube.
Install the pipe mounting “L” tabs at the
center line of the pipe and secure with
provided hardware, see Photo for
reference. Using your turbine for mock-up,
set the distance and pipe alignment. The
end of the pipe should be flush with the
rear section of the jet as shown in photo.
Once alignment is achieved secure pipe
with provided screws as shown in photo.
Bring smoke tube end out of the rear of the
pipe about 1.5 inches and bend down to
get into the hot exhaust stream. Adjust
rotation of smoke tube and then bend at
the bellmouth area as needed. We used Zip
Ties and mounts to secure smoke tubing.
Wire tie and run smoke tubing forward to
tray.

Engine to Pipe Spacing and Installation.
This is a crucial part of any engine
installation. Please refer to your engine
documentation for proper installation and
engine to pipe spacing practices. The
photos show a proper reference for engine
spacing and alignment.
You should have 1” spacing between the
end of the engine tailcone and the
beginning of the pipe inlet
(NOT THE BELL MOUTH)
The tailcone of the engine should be tucked
inside the bellmouth. Once center
alignment and distance is achieved, you
can drill/mount your engine using wood
style screws or bolts with blind/lock nuts.
Fuel Tank Assembly and Installation.
Pre-fit and dry install your fuel tank fittings,
you will drill can vent holes where needed.
NOTE: when locating the vent hole for the
fuel tank, be sure to pay attention to where
the split line is. You must be under the
tank/smoke tank separation line; you can
see inside the main tank for reference.
Carefully clean and Hysol in fittings. Note
fitting directions. Build tank clunk pick-up’s
as seen in photos. Be sure to solder collets
to both ends of the brass tubing. Measure
lengths of tubing as needed and pre-fit
after curing of fittings. Use wire tie to
secure fuel tubing. Pre-drill aluminum
mounting tabs before installing into
Midbody. Use provided wood screws to
install tank. We recommend a bead of
silicone around the front edge of the tank
to the fuel tray for added security.
Tank must be installed in Midbody
before nose section installation!

Page 7
Midbody & Nose Section Assembly.
After the nose gear installation is
completed, line up the Nose/Midbody
sections, apply Medium Thread Locker and
install top 2 bolts with the provided
wrench. (Lightly Tighten Bolts) then loose
install the remaining 5 bolts using Medium
Thread Locker and provided wrench.
Ensure proper alignment of the Nose and
Midbody sections and test canopy fitment
before fully tightening down the bolts. You
can use a straight edge across the fuselage
canopy edge surface to help with
alignment as well. You can use the Zip Tie
mounts to rout gear, steering and door
servo wires to the main tray area on the
right or left side of the nose gear
depending on your install.
TANK MUST BE IN MIDBODY BEFORE PROCEEDING!
Electric Nose Gear Installation.
Locate the nose gear steering horn and
install into strut using Medium Thread
Locker.
Install the steering servo using the
hardware that came with your servo to
mount onto the steering servo plate. Use
Medium Thread Locker
Center up your servo using a servo
centering device, adjust and install the
linkage as shown in photo.
Test fit the nose gear in the nose gear bay.
Verify that there is clearance between all
moving parts in the area such as the gear
door servo, arm, pushrod, and gear door
hinges. Mark hole locations and us a small
pilot drill for the holes then bolt gear into
place.

Electric Main Gear Installation.
Feed the main gear and brake wires to the
access area and plug into the wing wire
harness. (Always secure wire connections)
Slide the retract into place and locate the
strut, wheel and brake in the wheel well
making sure that you have equal distances
all the way around the tire and strut as
seen in photo.
When proper location is achieved, mark
holes and drill pilot holes, NOTE: Use a drill
stop to set drill depths as to not accidently
drill through wing. Use the (4) provided
screws to mount gear in place. Install gear
cover using provided hardware, slight
trimming may be required for fitment. Use
Aluminum tape to secure brake wires.
Electric Gear Controller Setup.
Each of the three gear units is
independently programmable.
• Long press the mode button to enter
programming mode.
• Short press the mode button to cycle
through the programming options below.
• When the A or B light is blinking, you can
press the + or –button to change the servo
direction. This setting is used if the door is
open when it should be closed or vice
versa.
• When the A and B lights are alternating,
pressing the + or –will increase or
decrease the servo throw on one end of its
movement. This setting is so that you can
adjust the door to open or close all of the
way without excessive binding at the
extents of motion.

Electric Gear Controller Setup Continued.
• When the C and D lights are alternating,
pressing the + or –will increase or
decrease the servo throw on one end of its
movement. This setting is so that you can
adjust the door to open or close all of the
way without excessive binding at the
extents of motion.
• The C light blinking alone indicates Mode
1 operation for that gear unit.
• The D light blinking alone indicates Mode
2 operation for that gear unit.
• When you have completed making your
programming adjustments, long press the
mode button to save your changes and exit
programming mode.
Electric Brake Controller Setup.
Connect the two-wire break leads from the
main gear to the “Brake output” port on
the side of the brake controller. Connect
the radio lead from the brake controller to
the appropriate channel that you have
configured for brake operation. Lastly,
connect the power lead to your power
source (7.4V-25.2V). Turn the strength
screw adjustments to their weakest setting
(completely clockwise). You will need to
execute some taxi and brake tests at your
flying location to tune the brake strength
and radio settings that will work best for
you. Ensure that you have your brakes and
landing gear tuned and working prior to
any flight operations.

Congratulations! You have completed the
assembly and configuration of your T-3
turbine sport jet!
Make sure you have another set of eyes give
your aircraft a good looking-over. Quite
often, a problem can be spotted by a fresh,
experienced pair of eyes. It’s better to find
and fix rather than fly and fail.
FLY SAFE AND HAVE FUN!!!
