VI. ASSEMBLY INSTRUCTIONS
1. Test fit the vertical stabilizer. Use a soldering iron or wood
burning tool to remove Mylar covering from the vertical stabilizer
that will be ‘buried’ inside the vertical slot at the rear of the
fuselage. Use 5-minute epoxy to secure the vertical stabilizer into
its slot at the top-rear of the fuselage.
2. Slide the supplied tail wheel onto the tail wheel strut. (You may
need to file or sand the end of the strut so the opening in the tail
wheel smoothly slides onto the strut.) Secure the tail wheel onto
its strut with a provided wheel collar. Position and secure a
second provided wheel collar at the top of the spring on the tail wheel strut.
3. Slide the tail wheel strut fully through the hole in the end of the aluminum tail wheel
mounting bracket, and test fit this tail wheel assembly at the bottom-rear of the fuselage so
the tail wheel’s wire strut aligns at the centers of the aft-ends of both the vertical stabilizer
and the fuselage. Measure 3/4-inch from the top end of the tail wheel’s wire strut and bend
the strut back (toward the rear of the airplane) at a 90-degree angle. Attach the tail wheel assembly to the
bottom of the fuselage with two approx. 9/16-inch (15-mm) long wood screws. (Apply thin CA adhesive to
reinforce these holes in the bottom of the fuselage.)
4. Test fit the rudder to the rear of the vertical stabilizer. Mark where a horizontal hole and a vertical notch are
needed in the rudder for the tail wheel’s wire strut. Drill the required hole and cut the notch in the front edge
of the rudder to fit the tail wheel strut’s wire.
5. With the rudder prepared for the tail wheel’s wire, apply some 5-minute epoxy to the end of the tail wheel
strut’s wire and insert the wire into the hole in the rudder. Before this epoxy thickens, insert two(2) supplied
CA hinges to secure the rudder to the vertical stabilizer and apply thin CA adhesive to the CA hinges; also
apply some masking tape to hold the tail wheel strut’s wire in position until the 5-minute epoxy has cured.
6. Using the provided 6 ea.
20-mm long steel bolts
and blind-nuts, attach
both halves of the
aluminum landing gear
struts to the bottom of
the fuselage.
(NOTE: See page 9 if
you are assembling your
Mentor-G V3 with
optional floats.)
S140131
Mentor-G V3
Page 4 of 10
7. Test fit the horizontal stabilizer, then use a soldering iron or wood-burning tool to remove the Mylar
covering that will be ‘buried’ inside its mounting- slot at the rear of the fuselage.
8. Using 5-minute
epoxy, secure the
horizontal stab. into
its slot at the rear of
the fuselage; before
this epoxy thickens,
make sure that the
horizontal stabilizer
is aligned at right
angles to the fuselage by measuring the distance between the outside rear
bolts on the landing gear and the outside end of each half of the horizontal
stabilizer – and adjust the horizontal stabilizer so this distance is the same
on both sides of the fuselage.
9. If you will use 1 elevator servo, insert
the prebent elevator connector into its
precut openings each half of the elevator as shown at the right. Test fit
the elevator to the horizontal
stabilizer. Use epoxy on both ends of
the prebent connector to both halves of the elevator. If you will use two elevator servos, do not connect the two halves of the elevator. Secure the elevator to the horizontal stabilizer by applying thin CA adhesive to each of the elevator’s CA hinges.
NOTE: a) For hi-stress aerobatic flying the Mentor-G’s tail section may be reinforced by adding stranded
metal wire (not included) to surround the entire empennage. Begin by attaching the wire at the bottom of
the fuselage, pass the wire through one end of the horizontal stabilizer, then through the top of the
vertical stabilizer, through the other end of the horizontal stabilizer, then draw it tight and attach it to the
bottom of the fuselage. b) If you convert the landing gear to a tricycle configuration, you may use scrap
plywood to reinforce the more-aft mounting position of the main landing gear on the bottom of the
fuselage and you may use a spare opening in the servo tray for your nose-wheel-steering servo.
10. Position the pushrod-openings in the control horns directly over the hinge lines and drill holes in the
rudder and elevator for the control horn mounting bolts. Attach one control horn to the rudder and one
control horn to the elevator. (Note: If you setup the elevator to be driven by two servos, remove the
covering material from the precut servo opening in the top of the fuselage directly in front of the rudder,
and mount your rudder servo in this ‘extra’ servo-mounting opening.)
11. Connect a 12-inch servo-wire extension to each of your rudder and elevator servos.
(Note: To ensure the security of your servo extension connections, we recommend you
install an optional “servo extension safety clip” at each servo wire/extension junction.)
12. Guide the servo extensions through the rudder and elevator servo openings and into the fuselage, then secure
the ends of the extensions inside the fuselage on the radio receiver’s tray with a piece of masking tape.
13. Using your servos’ hardware, mount your elevator and rudder servos in their openings. Using the
preformed Z-bends and the supplied clevises, attach the pushrods as shown. (NOTE: The provided
control horns give the ailerons, rudder and elevator a wide range of adjustability to accommodate the
builder’s preferences. We recommend beginner pilots start with the pushrods connected to the outermost holes; more advanced pilots may adjust pushrod positions for additioal throw, if desired.)
S140131
Mentor-G V3

14. Connect a 12-inch servo-wire extension to each of your aileron servos. Secure each connection with
an optional “servo extension safety clip” and use masking tape and the provided string to pull each
servo extension through its wing panel and out the hole near the wing root.
15. Insert the aileron’s CA hinges in their precut slots and test fit each aileron to its wing panel. Secure the
ailerons to their wing panels by applying thin CA adhesive to each of the aileron’s CA hinges.
16. Test-fit the aileron control horns. (Note: You may minimize the effects of any possible adverse yaw by
the use of ‘aileron differential’ by locating each servo horn slightly behind the aileron’s hinge line.
If you are not concerned about adverse yaw, or if you have a computer-radio with the option of setting up
aileron differential at your transmitter, position each aileron control horn direclty over the ailerons hinge
lines as shown.) Mark the position for each aileron control horn, then drill a hole in each aileron for each
aileron control horn’s mounting bolt.
Attach one control horn to each aileron.
Using your servos’ hardware, mount
your aileron servos in their precut
openings.
17. Use the supplied clevises to attach the
aileron pushrods to the aileron
control horns.
18. With your aileron servos centered, test-fit the free end free end of the
aileron pushrods to the control arms on your aileron servos. Form a
Z-bend in each pushrods, then use the hardware supplied with your
servos to securely mount the control arms with their aileron
pushrods to each aileron servo. (Note: If you wish to enjoy the
benefits of flying with flaps, use separate channels for the ailerons
and set up your computer-radio’s ‘flaperon’ function if available.)
19. Form a Z-bend in one end of the 13-inch long throttle pushrod. Insert the pushrod almost fully through
its opening in the firewall, leaving approx. two or three inches exposed in front of the firewall.
20. Select a servo control arm for your throttle servo that will provide enough pushrod ‘travel’ to go from ‘full
throttle’ to ‘just-below idle’ (i.e., throttle ‘cut-off’). Ream the hole in the throttle servo’s control arm to
accept the ‘mounting bolt’ in the end of the supplied quick-connector. Using the provided washers and
knurled mounting nut, ‘snugly’ attach the quick connector to the servo control arm, then permanently affix
the quick connector onto the servo control arm by applying a tiny drop of thick CA adhesive to the
exposed threads at the bottom of the quick connector’s mounting nut.
21. Slide the opening in the quick-connector onto the end of the throttle pushrod inside the fuselage;
temporarily tighten the quick-connector’s set screw to affix the quick-connector onto the throttle pushrod.
22. Select which of the fuselage-mounted servo tray options you prefer and mount your throttle servo in the
fuselage.
23. Assemble the provided fuel tank (i.e., open the ‘stopper’ for the vent and clunk lines, add the included
short length of fuel tubing to attach the clunk to the clunk line, and use the included screw to seal the fuel
tank’s opening). Attach clunk and vent fuel lines to the outside of the tank, and insert the tank into the
nose from the opening under the wing-saddle. You may use scrap wood or nylon tie wraps (not included)
to hold the fuel tank in position.
24. Test-position your engine’s battery and your receiver’s battery on the floor in the nose of the
fuselage.(During setup and adjustment you will re-position these batteries to fine-tune the CG.)
25. Decide on where you wish to position the engine’s and receiver’s power switches. You may
choose from among the precut switch openings, or decide on a new switch position if you wish.

(Note: Regardless of your engine’s or radio’s manufacturer, it is wise to maximize the distance
between your engine’s and your radio’s electrical components.)
Trial fit both switches (trim the openings if necessary) and install the engine and receiver switches.
Test-fit the engine’s ignition module immediately behind the firewall. Decide how
you plan to route the power, sensor and spark-plug wires. (Note: If you find the
ignition module’s spark plug cap does not easily pass through the hole in the firewall, you may relieve the inside top of the hole in the firewall with a drum sander
on a high-speed rotary tool; the ignition module may not include mounting flanges.)
Test fit your engine and muffler to the firewall. Use the engine’s supplied
standoffs, mounting bolts and blind-nuts to temporarily attach the engine to the
firewall, then determine and mark where wood may need to be cut away from the
front of the fuselage to allow clearance for the engine’s cooling fins and muffler.
Remove and set aside the engine.
Remove any excess wood identified above
and smooth all edges. Apply 5-minute epoxy
to seal and fuel-proof all exposed/raw wood.
Once the epoxy is cured, install your engine,
its muffler, and make all engine connections:
As you bring the engine toward the firewall,
your first connection should be the throttle
pushrod’s Z-bend; then, secure the four sets
of mounting bolts and standoffs and apply
Lock-Tite or a similar thread-locking
compound. (NOTE: EZ Link connectors may
Page 7 of 10
be used, but are not included.)
Route the high-voltage wire along the
engine’s left side, between the cylinder head
and muffler; route the sensor wire and the
fuel and vent lines along the engine’s righthand side.
Place the throttle servo’s control arm onto
your throttle servo’s output shaft, attach the
servo arm’s mounting screw, rotate the
servo’s shaft to ‘full throttle’ and position the
throttle servo so the engine’s throttle linkage
is at ‘full throttle.’ (NOTE: If necessary,
make a new hole in the firewall for the
pushrod to align with the location of the
carburetor’s throttle arm. We recommend you
do not void your engine’s warranty by
disassembling or modifying the engine.)
Cut away the Mylar covering material from the wing’s hold-down bolt holes and from the corresponding holes in the plywood wing hold-down plate.
Connect the rudder and elevator extensions, the throttle servo, and the receiver’s battery switch to your
receiver. If you are not setting up your radio for electronically-managed differential aileron response,
connect a Y-cable to your receiver’s aileron channel. If you have a computer-radio and will be setting up

aileron differential at your transmitter, connect two 6-inch servo extensions to the two channels you will
be using for aileron control. Wrap your receiver in cushioning foam rubber, position your radio receiver
on the radio tray and secure your radio receiver safely in position with criss-crossed rubber bands. (If you
are using a 72MHz. radio, route the antenna out of the fuselage and attach it to the top of the vertical stab.)
Slide the two wing panels toward each other on their supplied aluminum wing rod. As these two panels
merge, allow them to self-align onto the factory-installed wooden dowel-pins.
While holding the wing above the fuselage, connect the aileron’s extension wires to the corresponding
aileron wires attached to your receiver.
Align and insert the plywood projections at the middle of the wing’s
leading edge with the opening behind the ‘windshield’ in the fuselage, then gently lower the wing onto the fuselage’s wing saddle.
Place a flat washer onto each of the two (approx.
2 1/4-inch long) wing hold down bolts.
Guide the bolts (with their flat washers) through the
holes in the plywood wing hold-down plate, then into
and through the hold-down holes in the wing.
With the wing squarely aligned in the wing saddle, drive
these bolts firmly (but not so tight that wood becomes
crushed) into the fuselage-mounted blind nuts at the rear
of the wing-saddle. Then, carefully lift the airplane and
lay it on its back on a soft surface.
We recommend you add a short length of rubber tubing
(not included) at the inside-end of each axle to rub
against the wheel and cause friction – which acts as a
gentle ‘brake’ and helps reduce unwanted airplane
movement when you are landing and/or taxiing. This
friction is easily overcome during take-off by the
application of throttle.
42. Slide a provided mains-wheel onto each of two
(approx. 1 1/2- inch long) axle bolts.
Twist a supplied hex-nut onto each axle bolt against
the hub of each wheel (and adjust it to compress the
rubber tubing, if used).
43. Insert the remaining threaded end of each axle bolt
into the holes in the main landing gear struts.
44. Tighten a supplied self-locking nut onto the remaining
exposed threads at the inside of each axle bolt, secure
the axle bolt against vibration by applying a drop of
thick CA adhesive to the exposed threads at each self
locking nut, and return the airplane to its ‘right side up.’
Congratulations! Assembly is finished!

VII. FLOATS INSTALLATION AND SETUP
If you are considering flying your Mentor-G V3 with optional FLOATS, you may wish to see our
YouTube video at http://www.youtube.com/watch?v=PgHPmFH4FOc&lr=1&feature=mhum.
If you are not yet experienced at setting up a float plane, we recommend you review the detailed
floats instructions written for our profile P-47 and P-51 on pages 9 through 11 in the instruction
manual found on-line at www.maxfordusa.com.
We offer the following tips to help clarify the instructions packaged with the floats …
1. The steel struts provide strength and durability. Trace the hole-pattern from
the ends of the aluminum spreaders to drill mounting holes in the struts.
2. After you have attached the spreaders and struts to the floats, install an extra
layer of plywood inside the fuselage to reinforce the strut mounting points.
3. Position the floats’ STEP approx. 1-inch behind the Mentor-G’s center of
gravity. Drill two holes through each front and rear strut and through the
fuselage at approx. 8 1/4 and 21 inches behind the front edge of the fuselage.
4. Securely attach the struts to the bottom of the fuselage with mounting bolts and blind nuts.
5. Use an EZ Link Connector to attach one end
Toward the nose
of the rudder’s control cable to a spare hole
in the control arm of your Mentor-G V2’s
rudder servo.
6. Guide the cable in its housing forward from
the rudder servo along the fuselage, the
smoothly bend the cable/housing to the aftend of the right-side float, then use 2-piece
plastic clamps and a nylon wire-tie to secure
the cable’s position.
VIII. SETUP AND ADJUSTMENTS
1. For initial flights set the MENTOR-G V3’s center of gravity (CG) at approx. 3 3/4inches back from the leading edge of the wing. If necessary, move the batteries and/or
add weight to the nose or tail to ensure the CG is correct.
(Hint: Once you have determined the final position for your CG, you may secure both
the engine’s and radio’s batteries in place with double-sided foam tape and pack
some scrap foam rubber into the fuselage’s nose-area around the batteries and fuel
tank to help secure these items against vibration.)
2. Check the Mylar covering material’s joints and surfaces; if necessary, carefully use a
dedicated covering-material iron to secure the edges and to tighten any loosened areas.
Recheck and retighten from time to time.
3. Check/adjust servo centering, direction and end-point adjustments. When you pull the
right stick toward you, the elevator should deflect upwards; push the right stick to the
right and the right aileron should deflect upwards and the left aileron should deflect
downwards; push the left stick left and the rudder should deflect to the left as viewed
from the rear of the fuselage. Review your radio’s instruction manual if you require
assistance with any radio-related setup and/or servo-adjustment questions.
4. For initial flights set all linkages for near-max. possible deflections. If you are using a
Computer Radio: soften the aileron’s and elevator’s control throws by applying 30%
exponential.
S140131
Mentor-G V3
Page 9 of 10
Initial settings if you are using a Non-Computer Radio:
Low rates
High rates
Ailerons ................. +10 degrees (+3/8-inch) ........... +15 degrees (+1/2-inch)
Elevator ................. +10 degrees (+3/8-inch) ........... +15 degrees (+1/2-inch)
Rudder ................... +10 degrees (+3/4-inch) ........... +15 degrees (+7/8-inch)
5. Trim adjustments: The ailerons and rudder will probably require no adjustments (in all
probability you will be able to leave them centered, as assembled); however, be
prepared to set the elevator trim depending on how slow or fast you fly. For example, if
you like flying low and slow, your MENTOR-G’s elevator may require a bit of up-trim.
IX. PREPARATION FOR TRANSPORT AND FIELD SETUP
1. Unscrew and safely set aside the two screws that secure the wing to the fuselage.
2. Gently lift and slide the wing back, then lift it up and away from the fuselage.
3. Disconnect the two aileron servo extension cables. (If your radio uses separate channels
for each aileron servo, be sure to mark each aileron connection so they always get
connected to the same channel.)
4. To reattach the wings, reverse the above procedure. Be careful to firmly connect both
aileron servos and to snugly reattach (but not over-tighten) the wing hold-down screws
into the blind nuts inside the fuselage.
X. PRE-FLIGHT CHECKS
1. Double-check the security of the engine, and make certain that all screws, linkages,
clevises and other connections throughout the air frame are secure.
2. Double-check the control directions of the throttle, ailerons, elevator and rudder.
3. As with all radio-controlled model airplanes, this model must pass the radio range
ground check recommended by your radio’s manufacturer, or you may not safely fly.
4. Get into the habit of moving your transmitter’s throttle to minimum before turning ON
your transmitter, and carefully break-in and operate your engine according to the
manufacturer’s instructions.
REMINDER: T H I S P R O D U C T I S N O T A T O Y .
