Congratulations on your acquisition of Maxford USA’s version of the Hughes H-1 from the Golden Age

of Aviation – the 20-year period between the end of World War I and the beginning of World War II.

The H-1 was Hughes Aircraft Company’s first aircraft. Though originally conceived simply for speed, the H-1 had many

new features that influenced the design of high-performance aircraft for years, including …

• Retractable landing gear.

• Gently curving wing fillets between the wing and the fuselage to help

stabilize airflow, reduce drag, and prevent potentially dangerous eddying

and buffeting.

• Rivets and joints made flush with the aircraft’s aluminum skin.

• The ailerons could be drooped 15 degrees when the flaps were fully

extended, improving lift along the full length of the wing for takeoffs

and landings.

With Howard Hughes at the controls in 1935, the H-1 succeeded in breaking

the world land-plane speed record, clocking 352 mph over a specially

instrumented course near Santa Ana, California. Hughes then set a

transcontinental speed record, flying his H-1 at an average speed of 322 mph,

non-stop from Los Angeles to New York City in 1937. The original H-1 was

donated to the Smithsonian National Air and Space Museum in 1975, where it

remains on display in the Golden Age of Flight gallery.

After nearly 2 years in development, this model of the H-1 is smooth and stable at both low and high speeds. True to the

original, all of the rudder, elevator and aileron linkages are fully concealed within the fuselage, giving this model a more

scale-like, streamlined appearance. This Hughes H-1 model also includes a spring-loaded tail wheel, magnetic battery hatch,

scale fixed landing gear plus the option to easily add retractable landing gear, and a new “Max Cowling” fiberglass cowl.

(Developed by Maxford USA for RC airplanes, "Max Cowling” is a new technology to preserve the cowl’s smooth, scale-like

appearance and to make removal and reattachment quick and easy. With this technology, just push and twist, and the cowl is

safely secured with 3 screws and a magnet.)

Enjoy the pride of ownership and the joy of flying this high-quality model of the famous Hughes H-1!

HUGHES H-1 ASSEMBLY INSTRUCTIONS

Step 1: Power system.

1. Solder connectors to the motor’s and the ESC’s matching sets of 3 hi-current wires, and solder a polarized

connector to the ESC’s and battery’s red and black leads. If your connectors are not already fully insulated, cover

exposed metal surfaces at each connection with heat-shrink tubing to prevent short circuits. (At this time leave

the motor’s 3 wires NOT connected to the ESC’s 3 wires, do NOT connect the ESC to the battery, and do NOT

attach a propeller to the motor.) Set aside the ESC and the battery.

2. Using the predrilled holes in the motor-mount pylon and 4 screws provided by the motor’s manufacturer, attach

the motor to the front, outside of the motor-mount pylon. Connect the

motor’s 3 wires to the ESC’s 3 wires, plug the ESC’s 3-wire

BEC/throttle connector into the receiver’s throttle channel, connect

your aileron, elevator and rudder servos to the receiver, and check the

motor’s rotation (and center your servos) as follows …

a. If you are using a computer radio, ensure the transmitter’s “end

point adjustments” are set to their normal, full-range settings. Set

the transmitter’s throttle and throttle trim controls to minimum and

center the transmitter’s aileron, elevator and rudder trim controls.

With NO PROPELLER on the motor, switch ON the transmitter.

b. Connect the ESC to the battery and listen for a series of initialization

sounds from the ESC, and the aileron, elevator and rudder servos should travel to their centered positions. Then,

raise the transmitter’s throttle stick approx. halfway up, and the motor should power-up in the clockwise

direction as viewed from the rear of the airplane. If so, proceed to step 3.

c. If the motor powered-up in the counterclockwise (wrong) direction as viewed from the rear of the airplane,

return the throttle control to minimum, disconnect the ESC from the battery, swap either 2 of the 3 ESC to

motor wires, and repeat “a” and “b” above to ensure the motor rotates in the correct direction.



Page 6 of 13 pages

3. With the servos centered and the motor tested, return the transmitter’s throttle control to minimum, disconnect the

ESC from the battery, switch OFF the transmitter, and set aside the battery, receiver, servos and transmitter.

4. Insert the ESC into the front of the fuselage-mounted battery box; then slide the motor-mount pylon onto the

battery box, with the magnet cutouts aligned with the magnets on the bottom of the battery box, and positioned so

that the tip of the motor’s shaft is approx. 4¼ inches from the front edge of the firewall.

(Note: Depending on the size of your motor and its collet, you may need to adjust the motor opening in the

“Max Cowling” to complete #5.)

5. Temporarily install the “Max

Cowling” and a propeller onto

the motor’s shaft. Make sure

the rear of the propeller’s blade

does not strike the front of the

cowl by repositioning the

motor-mount pylon on the

battery box. Then remove and

set aside the “Max Cowling”

and propeller, and secure the

motor-mount pylon by driving

4 ea. 3/8-inch long wood screws through the motor-mount pylon’s predrilled holes (two on each side) and into the

battery box. (NOTE: You will have the opportunity to fine-tune the propeller/cowling clearance when

you finally mount and position the propeller on the motor’s shaft in step 4.)

Step 2: Tail group (with rudder and elevator servos and the receiver) and canopy.

6. Remove and set aside the cockpit’s clear plastic canopy by lifting off two pieces of masking tape. If you will

NOT be using a 72 MHz. receiver in this airplane (i.e., If you plan to only use a 2.4 GHz. radio system in this

airplane), proceed to step 7. If you WILL (or may) use a 72 MHz. receiver, insert a drinking straw that reaches

from the hole in the fuselage former at the front of the tail group into the cockpit area, and secure each end with a

drop of CA adhesive.



Page 7 of 13 pages

7. Assemble the rudder (short) and tail-wheel (long) control arms,

the two pushrods, and their plastic keepers, as shown …

8. Insert the tail wheel’s mounting rod into the hole in the bottom

of the fuselage. As you feed the rod up through this hole, place

the long control arm and the small wheel collar onto the rod.

Position the rod’s top end just beneath the top surface of the

horizontal stabilizer’s mounting platform. Space the wheel

collar and the long control arm to hold the rod in this position,

then firmly tighten the setscrews in the wheel collar and long

control arm to secure the rod’s position.

9. Place the horizontal stabilizer with its prehinged elevators onto

the horizontal stabilizer’s mounting platform. Look down into

the small rectangular opening toward the rear of the horizontal

stab. and position the horiz. stab. so its opening is aligned

with the same-sized opening in the horizontal stabilizer’s

mounting platform. With these slots aligned, secure the

horizontal stab. to the horizontal stabilizer’s mounting

platform with a few drops of CA at both the top and

bottom surfaces of the overlapping round holes.

10. Install the vertical stab. rudder control rod and hinge rudder by guiding

the rudder’s control rod down into the opening in the short control arm

and insert-ing the tab at the front of the vertical stab. into the opening

in the fuselage former at the front of the tail group. Press the tabs on

the bottom of the vertical stab. fully into their openings in the

horizontal stabilizer. Apply CA adhesive to all contact surfaces

(including the tip of the tab beneath the horizontal stabilizer’s

mounting platform).



Page 8 of 13 pages

11. Position the two wooden empennage/fairing reinforcements on top of

the horizontal stabilizer, on each side of the vertical stabilizer.

Apply a drop of CA adhesive where these reinforcements touch the

vertical and horizontal stabilizers, as well as where they touch the

fuselage former at the front of the tail group.

12. Secure the rudder in a neutral/straight-ahead position with a small

piece of masking tape. Then, while holding the rudder and tail-

wheel control arms in neutral/side-to-side position,

move the short control arm approx. 1/8 inch above

the lower end of the rudder’s control rod, and

securely tighten the short control arm’s setscrew

against the rudder’s control rod.

13. Notice that one of the Z-bend wires in the ends of

the elevator pushrod (which is over 19 inches

long) is firmly fixed, but the Z-bend wire in the

other end can be adjusted. Insert the adjustable

end of this pushrod into the fuselage through the

opening in the last fuselage former, and guide it

toward the area of the servo tray.

14. Twist and turn the push-pin-type elevator’s control

horn to attach it to the the Z-bend in the aft (rear-

most) end of the elevator’s pushrod. Mount the push-pin-type control horn

approx. 1/8 inch off-center on the underside of the elevator’s joiner,

secured with a drop of CA adhesive.

15. Mount the elevator servo

in its precut servo-tray

slot using the hardware

supplied by the servo

manufacturer. After you

have determined the servo

mounting screw locations,

use CA adhesive to

harden the servo tray’s

wood where the screws

will be inserted. Hold the

elevator in its neutral/

centered position while adjusting the pushrod’s length; then, connect the pushrod to the elevator servo’s arm and

attach the servo arm to the servo. Permanently secure the location of the Z-bend wires within the elevator pushrod

by applying a drop of CA adhesive to both ends of the pushrod where the Z-bend wires meet the pushrod’s tube.

16. Use two crimp-tubes to attach the two rudder cables to

two metal snap-hooks. As you attach the cables, keep

the loops (shown over-sized in the photo for routing-

clarity) to a minimum. To perform the cable-

attachment process: a) Slide a crimp-tube onto the

end of a cable; b) Pass the end of the cable through the

snap-hook’s small end; c) Bring the end of the cable

back into and all the way through the crimp-tube;

d) Loop the end of the cable back into the crimp-tube,

but this time leave the end of the cable inside the crimp-

tube; e) Using long-nosed pliers, firmly squeeze

several places along the length of the crimp-tube to

crimp the tube securely onto the cable.



Page 9 of 13 pages

17. Temporarily anchor both loose cable-ends to the servo tray with a piece of masking tape. Then, temporarily attach a

small weight to the metal snap-hooks, feed the weight and metal snap-hooks through the fuselage, and bring them

out through the largest hole in the fuselage former at the front of the tail group. Remove the weight, and connect

one metal snap-hook to each of the second-from-the-outside holes on the long tail-wheel control arm.

18. Mount the rudder servo in its precut servo-tray slot using the hardware supplied by the servo manufacturer. After

you have determined the servo-mounting-screw locations, use CA adhesive to harden the servo tray’s wood where

the screws will be inserted.

19. Connect each of the two clevis assemblies to the

rudder servo’s arm, and attach the arm to the

rudder servo. Free one loose cable end from its

masking tape, place a crimp-tube on the cable,

and pull the cable “snug” between the long tail-

wheel control arm and the brass pull-rod

screwed into the end of the clevis. (Don’t pull

so hard that the servo arm or rudder is moved

from its centered position, and don’t allow the

cable to get wrapped around the elevator

pushrod.) Once the cable is snug, use the crimp-

tube to secure this rudder cable to the brass pull-

rod in the end of the clevis. Use the same

attachment process as in #16, except: When you

loop the end of the cable back inside the crimp-

tube for the last time, allow the excess cable to

extend out of the crimp-tube; then, after you have crimped the tube securely onto the cable, snip off the excess cable

with a pair of diagonal or side-cutter pliers and discard the excess cable.

20. Free the second loose cable-end from (and discard) the piece of masking tape. Place a crimp-tube on the cable, and

(using the same process as in #19) pull this cable “snug” between the long tail-wheel control arm and the brass pull-

rod screwed into the end of the clevis, and use the crimp-tube to secure this rudder cable to its brass pull-rod.

21. Screw the brass pull-rods further into or out of each clevis to adjust the tension on the cables and center the rudder;

then secure the adjustment by tightening the lock nut on each brass pull-rod against its clevis. Remove and discard

the piece of masking tape (applied at the start of #12) from the rudder.

22. Connect the rudder and elevator servos and a

6-inch servo-wire extension for the ailerons to

your receiver. (Connect a second 6-inch

servo-wire extension to the receiver if you are

using the optional retracts.) Position your

receiver in front of or behind the servo tray

(or, if you are using one of Spektrum’s

multiple receiver options, use both of these

locations) and secure the receiver(s) with

Velcro-brand or equivalent adhesive-backed

hook-and-loop material. If you use a 72 MHz.

receiver, guide the antenna wire out of the cockpit area and into the

end of the drinking straw. Push the antenna through the straw,

down through one of the holes in the horizontal stabilizer’s

mounting platform, and out through the opening in the last fuselage

former, where it will be left to simply dangle behind the aircraft.

23. Test-fit the upper empennage fairing. (Normal production toler-

ances and minor variations in assembly may make it necessary to

slightly trim the top and/or front edges where the upper fairing

meets the vertical stab. and the fuselage former at the front of the

tail group.) If required, trim carefully. Do not take off too much.



Page 10 of 13 pages

(Note: Some H-1 owners have reported they attached the upper empennage fairing and/or the canopy by simply using

a little clear tape, such as Scotch-brand clear tape or equivalent! If this is your choice, skip #24 through #29.)

24. Once you are content with the fit of the upper empennage fairing, sparingly apply a uniform amount of windshield

glue (such as J & Z Products’ “Z RC/56” or equivalent) along the following areas:

a. The horizontal, left and right sides of the outer edges of the wooden empennage/fairing reinforcements.

b. All the top edges on both sides of the

fuselage former at the front of the tail

group.

c. The inside-top, curved surfaces of the

upper empennage fairing, wherever the

fairing touches the sides of the vertical

stabilizer.

25. If you will NOT be using a

72 MHz. receiver in this airplane

(i.e., If you plan to only use a 2.4 GHz.

radio system in this airplane), proceed to

#26. If you are using a 72 MHz. radio, pull

firmly but gently on the end of the antenna’s wire to

“stretch” the wire between the end of the drinking straw and

the hole in the horizontal stabilizer’s mounting platform.

(This mild tension on the antenna wire will keep the wire

from sagging into any excess glue applied beneath the

upper empennage fairing in #26.) Use a piece of masking

tape to secure the end of the antenna wire to a fixed object,

or connect a small weight to the end of antenna wire to

maintain enough tension to keep the wire safely out of the

way while the adhesive dries.

26. Carefully position the upper empennage fairing into its final

position around the vertical stabilizer. Wipe away all

excess windshield glue, and use bits of masking tape to

align and hold these gently curving, smooth surfaces in

position while the windshield glue dries.

27. Test-fit the cockpit canopy. (Normal production tolerances

and minor variations in assembly may make it necessary to

slightly trim the bottom and/or rear edges where the cockpit

canopy meets the fuselage.) If required, trim carefully. Do not take off too much.

28. Once you are content with the canopy’s fit, sparingly apply a uniform amount of windshield glue (such as

J & Z Products’ “Z RC/56” or equivalent) along the outer edges of the canopy’s inside surfaces. Then,

carefully position the canopy into its final position over the cockpit. Wipe away all excess windshield glue,

and use bits of masking tape to align and hold the canopy in position while the windshield glue dries. Plan on

a drying time of at least 3 hours (overnight is better).

29. Set aside the fuselage to allow the windshield glue to fully dry, and immediatley proceed to step 3, below.

Step 3: Aileron servo and landing gear.

30. Using the hardware supplied by the servo manufacturer, mount the aileron servo in the rectangular opening behind

the spar; route the aileron servo’s wire through oval hole beside the aileron servo. Use CA adhesive to harden the

servo rail’s wood where the screws will be inserted.

31. Connect the Z-bend in each of the two aileron pushrods to the aileron servo’s arm, attach the arm to the aileron

servo, and slide a plastic pushrod keeper onto each aileron pushrod. Twist a nylon horn bracket onto each of the

two aileron torque rods’ threaded ends.



Page 11 of 13 pages

32. Secure each aileron in a neutral position with masking tape. Line up each pushrod beside its mating nylon horn

bracket, place a mark on each pushrod at the pushrod opening in the nylon horn bracket, and make a sharp 90-

degree bend in each pushrod at this mark.

33. Leaving approx. 3/16 to 1/4 inch of pushrod

wire after the bend, cut off and discard the

remaining, excess pushrod wire. Insert each

pushrod’s bent end into its mating opening in

each of the nylon horn brackets. Use a plastic

pushrod keeper to secure each aileron

pushrod/nylon horn bracket connection.

Remove and discard the masking tape from

each of the ailerons.

34. If the pushrod(s) did not get bent at

exactly the right place and one or

both of the pushrods is too long,

fine-tune the length of the too-long

pushrod with a series of three small

bends.

35. Install the supplied scale fixed landing gear …

(Note: If you are going to install the optional retractable landing gear at this time, skip #35 and follow the

instructions supplied with the H-1’s mechanical retracts.)

35.1. Remove and discard the piece of masking tape that holds one of the fixed-landing-gear mounts into the wing

and lift out the fixed-landing-gear mount.

35.2. Slide a blue metal fixed-landing-gear retainer onto one of the preformed fixed-main-landing-gear wires.

35.3. Put a wooden fixed-landing-gear retainer

with its edge that is painted blue

facing toward the blue metal

fixed-landing-gear retainer, and positioned

within the “squared-U” shape at the end of the

preformed fixed-main-landing-gear wire.

35.4. Position the preformed fixed-main-landing-

gear wire‘s coil nearest to the fuselage, and

start it into the slot in the fixed-landing-gear

mount. Start 2 ea. 1/2-inch screws through the

blue metal fixed-landing-gear retainer and

into the fixed-landing-gear mount. Place the

fixed landing gear mount back into the wing,

then tighten the screws as you firmly press the

preformed fixed main landing gear wire with

the wooden fixed-landing-gear retainer into the slot. Secure

the fixed landing gear assembly to the wing with two more

1/2-inch screws.

35.5. Install the other scale fixed landing gear by repeating

#35.1 through #35.4, above.



Page 12 of 13 pages

35.6. Loosely mount both wheels (do not tighten the wheel-collar setscrews).

Using the main wheels as a visual guide, position a landing gear legging

onto each of the preformed fixed main landing gear wires. Remove the

wheels, and secure the landing gear leggings using two 3/16-inch screws

through each of the landing gear legging mounts and into the attachment

points on each legging. Re-mount both wheels and firmly tighten the

setscrews in their wheel collars.

35.7. Prevent the landing gear leggings from accidentally rotating by applying

a drop of CA where the upper landing gear legging mount touches each of

the preformed fixed main landing gear wires.

36. When the windshield glue is fully dry from #29, remove the masking tape from

the upper empennage fairing, vertical stabilizer, and rear

of the fuselage; then remove the masking tape from the

canopy and fuselage. Clean any dried glue or residual

masking-tape adhesive with a glass cleaner such as

Windex or the equivalent. Align the opening in the

bottom-center of the lower empennage fairing with the

steerable tail-wheel rod, and, as you slide the lower

empennage fairing into position, capture the ends of the

upper empennage fairing at the rear of the fuselage

inside the end of the lower empennage fairing. Bring the lower empennage fairing toward the

fuselage and it will secure itself in position using the supplied, premounted magnets.

37. Inert the opening at the top of the tail-wheel bracket onto the steerable tail-wheel rod, align the

wheel’s direction with the rudder, and firmly tighten the combination setscrew/spring mount-

ing bolt to secure the tail wheel to the rod.

Step 4: “Max Cowling” and propeller.

38. Align the keyed-slots inside the “Max Cowling” with the

three screw-heads mounted at the front of the firewall;

twist the cowl clockwise and it securely locks in position

by means of a rare-earth magnet.

39. Install a propeller onto the motor’s shaft. Make certain

the rear of the propeller’s blade does not strike the front

of the cowl by careful placement of the propeller’s

mounting collet on the motor’s shaft.

Step 5: Attach the wing, and final setup.

40. Cut away the covering material to open the precut wing-mounting holes for the plastic wing bolts; connect the

aileron servo to the 6-inch servo-wire extension for the ailerons; align and insert the 2 carbon rods pre-installed at

the center of the wing into the corresponding openings at the bottom of the fuselage; then, insert the two nylon

bolts through the two holes at the trailing edge of the wing and snug them into the threaded holes inside the

fuselage (but do not tighten them so much that the wing’s trailing edge becomes deformed or crushed)..

41. Charge and install your Li-Po battery. Check/adjust servo centering, direction, and end-point adjustments. Please

review your radio’s instruction manual if you require assistance with any radio-related, servo-adjustment

questions.

42. Close the battery hatch. (Note: The battery hatch is secured by one carbon fiber rod at the rear and two magnets at

the front. TO OPEN the battery hatch, push FORWARD until the rod clears the hole in the bulkhead, then pull UP.)

43. Check the model’s center of gravity (CG). If necessary, try moving the battery, ESC, and/or receiver, or add weight

to the nose or tail, to ensure the CG is 3 to 3¼ inches behind the leading edge of the wing, measured next to the

fuselage.

44. Recommended setups and adjustments:

• With a Computer Radio, set aileron and elevator control linkages for max. possible deflections and soften the

aileron’s and elevator’s control throws by selecting 60% (or more) exponential, and 30% for the rudder.

• Non-Computer Radio: Low rates High rates

Ailerons …….. + ½ inch ………. + 1 inch

Elevator …….. + ¾ inch ………. + 1 inch

Rudder ……… + ¾ inch ………. + 1 inch

Congratulations, assembly is complete!

Final Checks Before Flying:

1. Check that all screws, linkages and connections are secure, but do not overtighten the nylon wing bolts.

2. Double-check the control directions of the ailerons, elevator and rudder (i.e., pull the right stick toward you

and the elevator should deflect upwards; push the right stick to the left and the left aileron should deflect

upwards and the right aileron should deflect downwards; push the left stick right and the rudder should

deflect to the right as viewed from the rear of the fuselage).

3. Make sure that all controls operate smoothly.

4. 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.

5. When you are ready to fly, always be in the habit of moving your transmitter’s throttle and its trim control to

minimum, turn on the transmitter; then connect the airplane’s battery to the ESC.

REMEMBER: A ROTATING PROPELLER IS DANGEROUS!

• ALWAYS SWITCH THE TRANSMITTER ON (WITH ITS THROTTLE ALL THE WAY DOWN) BEFORE

CONNECTING THE BATTERY TO THE ESC, AND ALWAYS RETURN THE THROTTLE TO MINIMUM AND

DISCONNECT THE BATTERY FROM THE ESC BEFORE SWITCHING THE TRANSMITTER OFF.

• HANDLE THE MODEL WITH EXTREME CARE WHENEVER THE BATTERY IS CONNECTED TO THE ESC.

• STAY CLEAR OF THE PROPELLER AND THE PROPELLER’S ARC.
