ASSEMBLY:

1. Locate aileron control horns and push rods. Install the aileron control horn using the

screws and screw driver provided. Now connect the pushrod to the aileron servo

horn as shown. Repeat this step for the remaining wing panel.

2. Using a sharp scalpel, cut both ailerons free of the main wing at the tip leaving 1mm

of clearance. Ensure your cut is at a equal distance from the wing tip for both ailerons.

PB1.7 x 10mm

3. Locate the plywood wing spar and glue it into either one of the wing panels. Push

the spar into the wing until the center of the spar meets the edge of the wing panel

as shown. Apply some glue to this same edge and the exposed portion of the spar.

Now push the remaining panel fully onto the spar until both sides meet, ensuring

both wing halves are completely aligned with one another at the center and that all

wires are pulled neatly through to the top of the wing. It is recommended that you

do a dry assembly of all parts first.

4. Glue both wing bolt plates into place on the wing and set the wing aside until

the glue has completely cured. Again ensure the wing remains fully aligned at the

center when left to dry.

5. Offer the completed wing up to the underside of the fuselage installing the leading

edge first. Pull through all wires from the wing into the opening of the fuselage,

ensuring the wing sits centrally to the fuselage when installed as shown. Use one of

the two wing bolts (35mm in lenght) to secure the trailing edge of the wing to the

fuselage.

6. Referencing the images below, locate the bomb rack and place over the front wing

bolt plate. Ensure the wing bolt hole at the front of the rack lines up exactly over the

hole of the front wing bolt plate. Use the remaining wing bolt to secure the leading

edge of the wing to the fuselage.

PM3.0 x 35mm

7. The bombs can now be glued in place. Alternatively velcro can be used to make

them removable.

8. Locate the vertical stabilizer and install the rudder control horns as shown. Now

glue the vertical fins to both ends of the horizontal stabilizer ensuring they at 90° to

the tail as illustrated. Put the tail aside and allow the glue to dry.

9. With the fins firmly glued in place, the rudder control rods can be installed. Power

up the servo’s to center and raise the arms. You’ll now be able to access the control

horns easily to connect the push rods as shown.

10. Locate the elevator control horns and install as shown. Connect the rudder servo

leads to the Y-lead that’s taped in place at the rear exit of the fuselage.

11. Pull forward into the fuselage as much of the rudder Y-lead as possible. Then with

the tail plane turned over, apply glue to the entire portion of the fuselage shown.

PB1.7 x 10mm

12. Flip the tail plane back over and position firmly in place on the fuselage, pulling

through any remaining servo leads as you do. Ensure there are no gaps and that

the tail is level and aligned correctly to the wing and fuselage. Measuring equal

distances bewteen the point shown with ensure this.

13. Once the tail glue has dried, center the elevator servo and connect the elevator

clevises to the control horns as shown.

14. The final stage of assembly is to fit the props and spinners. Pay close attention

when fitting the props and ensure that both motors turn in towards the fuselage when

the motors run. The right hand side motor/prop (looking from the front) turns in a

anti clockwise direction with the leading edge of the blades facing the fuselage and

the left hand side motor (looking from the front) turns in a clockwise direction, again

with the leading edge of the blades facing the fuselage. The images shown below fully

illustrate the correct installation of the propeller and correct rotation of the motors.

15. Once you have established propeller orientation, offer each prop up to the prop

shafts and locate into position on the spinner back plate. Use the nut from the prop

shaft to secure the prop in place on the shaft. The spinner can now be screwed in

place but be sure to double check that each blade retaining bolt is secure and all

blades are at an equal distance from one another before you do.

16. Locate all numbered servo Y-leads and connect to their corrosponding servo

leads. Connect these servo leads to your receiver of choice (as stipulated by

your receiver manufacturer). Connect the esc Y-lead (supplied) to both XT60

plugs that exit the center section of the wing as shown. Note the UBEC coming

from the esc Y-lead. This powers your receiver and servos and should be

connected to any free port of your receiver. With all leads now connected, install

your receiver in the location shown, keeping all cables as tidy as possible. A

Hobbyking OrangeRx R620 recevier is shown and recommended.

Assembly of your Bf.110 is complete.

Now perform a final check on all screws, bolts and components,

ensuring all are secure and firmly in place.

SETTING UP YOUR MODEL:

1. Once you have established a connection between your receiver and transmitter

turn on your transmitter followed by your receiver (by connecting your 2200mah 3s

lipo to the speed controller (ESC). Also ensure the battery is fully charged.

2. With the electronics powered up and the servo's centered, ensure that all control

surfaces are level. If not, adjust by turning the control clevis's accordingly until the

control surfaces are level as shown below.

3. Check all control surfaces are moving in the correct direction with the correct stick

input (see below).

4. The Bf.110 handles extremely well in flight, and on the ground and setting it up

correctly is vital. The following set-up below is recommended for the best Flight

performance.

Control throws:

* Elevator ‘low rates’ 8mm ‘high rates’ 12mm in either direction from neutral.

* Aileron ‘low rates’ 6mm ‘high rates’ 10mm in either direction from neutral.

* Rudder ‘low rates’ 6mm ‘high rates’ 8mm in either direction from neutral.

CG Location:

5A. The suggested CG for the Bf.110 is approximately 60-70 mm from the leading

edge of the center section of the wing. With a 2200mah 3S lipo installed the model

should balance between these points. The C/G given will make for the best all

round sports/scale flying characteristics though you maybe want to adjust this later to

better suit your own flying style. Do this by moving your flight battery more fore or aft.

5B. It is recommended that velcro be used to hold your flight battery firmly in place in

the model. Note the location of the recommended Turnigy 2200mah 3S lipo when

installed in the fuselage. This is the correct approximate location for installing the

lipo and achieving the suggested CoG.

With assembly and set-up now complete, your Durafly Bf.110 should be ready for

flight. However we recommend you read and follow the advice given in the next stage

of this manual before flying your Messerschmitt.

MODEL FLYING PRECAUTIONS:

- Select your flight area carefully. Always choose an open space that is unobstructed

from trees and buildings and away from crowed area's. Avoid flying in area's with

roads, electric/telephone poles/wires and water near by or within close proximity to

full size air traffic.

- Do not fly this model in poor weather. High winds, low visibility, inclement

temperatures, rain and storms are to be avoided.

- Never attempt to catch this model whilst in flight. Even a slow moving model can

cause harm to yourself and/others and risks damage to the model.

- This model is recommended for children no younger than 14 years old. All children,

not matter what age, should always be supervised by a capable and responsible

adult when operating this model.

- Always unplug your model battery when not in use. Never leave the battery installed

in the model.

- Please remember to keep clear of the propeller at all times when your flight battery is

connected.

- Before flying, always turn on your transmitter first then plug your flight battery into

the model.

- After flying, always unplug your battery first then turn off your radio transmitter.

- Exercise caution when charging your batteries and follow in full your battery

manufacturers safety guideline when doing so.

BF-110

PRE-FLIGHT CHECKS:

1. Always range check your model before any flight (especially when flying a new

model for the first time). Follow your radio manufacturers guidelines for performing

this check.

2. Check all screw/bolts and mounting points are firmly secured, including control

horns and clevises.

3. Only fly with fully charged batteries (both in your radio and model). Failure to do

so could result in loss of control, damage to the model and/or persons/property

around you. Check your batteries are fully charged.

4. With the model powered up (Transmitter on first, then receiver/model) check that all

surface are free from damage/obstructions, moving in the correct directions and

freely with stick input.

5. Inspect the model and prop for any damage that may have occurred during transit

and listen for any unusual sounds from the electronics when powered up. If in

doubt, do not fly.

6. With the model held securely and the prop free of obstructions, increase the throttle

just slightly to confirm the rotations of the prop is correct. The model should want to

pull straight forward with throttle.

7. If this is your first flight with the model double check the C/G is at the correct

position. If not adjust battery position inside model accordingly.

8. If you are an inexperienced model pilot seek the help and assistance of an

experienced pilot to perform these final checks and to test fly the model for you.

FLYING THE BF.110:

The Durafly Bf.110 may be close to scale in its outline, yet it flies exceptionally well for a twin

engined model. With its counter rotating configuration and powerful set-up, the Bf.110

enjoys a great flight envelope, maintaining its maneuverability and aggressive stance in the

air throughout the speed range. Use of rudder in the air (although not completely

necessary), does add its overall flying prowes when used in turns and of course

complements the steerable tail wheel on the ground. The Bf.110 is capable of all manner of

scale and sports maneuvers yet will not bite you in the stall, benefiting from very benign stall

characteristic. With the recommended 2200mah 3S lipo you have a good combination of

power, with respectable flight times. You should typically expect flight times of approximately

7 minutes with varied throttle use in flight. For greater duration you can of course fit a higher

capacity pack (the Bf.110 will handle the extra weight). On the ground the handling is

excellent on both short grass and paved surfaces, though hand launching would be advised

if you're flying from longer grass.That said, this Bf.110 does hand launch easily.

Taking off directly into wind should require no more than 3/4 throttle to be off the ground.

Care should be taken to increase throttle slowly during taking off, allowing time for any

correction to direction with the rudder/tail wheel, whilst allowing speed/lift to gradually build.

It is recommended that some up elevator be held in for the initial rollout to help keep the tail

down whilst you build up speed, and to prevent the model from nosing over. As momentum

starts to build, gradually reduce the amount of 'up' you have held in to allow the tail to lift.

From this point the Bf.110 should take to the air with minimal amount of further 'up' elevator.

If you do wish to hand launch your model, this should be done with full power into wind and

at a slightly nose up angle with the wings level and the landing gear retracted. Climb out

from hand launch is good, with no noticeable loss in height immediately after launch.

Flying a twin engined model is an exciting and unique experience yet has traditionally been

more of a challenge. With the Durafly Bf.110 however you needn't worry. It easily handles as

good as any of the single engined warbirds in the range whilst, providing that twin sound and

experience in the air. All basic aerobatic maneuvers can be done with ease at full throttle

(even more so with coordinated stick inputs). For closer to scale flying you'll want to bring

the throttle down to approximately 3/4 throttle. Here you'll benefit from a more realistic speed

and a slight lengthening of flight times, whilst maintaining complete maneuverability. Also to

avoid over heating your motors and ESC's, it is generally not recommended to fly on full

throttle for the entire duration of the flight. In slow flight the Bf.110 still maintains a good level

of control and authority for both low/slow fly-bys and landings. The Bf.110 does land easily

and will not present a challenge for pilots with low wing experience. When you are ready to

land, lower the gear on the down wind leg to help the model bleed off excess speed ready

for when you make the turn into the approach. A high angle of approach is recommended as

this will help maintain a steady descent rate when coming into land. The Bf.110 has a

reasonable glide for a twin, but the drag of an additional prop does need to be taken into

consideration. So, always 'fly' into your landing with the combined use of throttle and

elevator. As you flair for landing, be sure to hold in some additional up elevator once you’ve

touched down. This will prevent the bf.110 from tipping up onto its nose especially when

landing on longer grass. Once down, you can enjoy the exceptional ground handling of the

Messerschmitt thanks to its tough metal trunnion electric retracts and steerable tail wheel.

Happy flying and thank you for choosing Durafly.

BF.110 TIPS:

1. Whilst not essential to flying, the use of rudder in flight will greatly improve the look

of the model as it flies through maneuvers. It will let you explore the full potential of

this fine model and improve your flying skill. A mix of 40% aileron-rudder is

recommended as a good starting point.

2. Although it can be, the Bf.110 doesn’t need to be flown at full throttle all the time.

Dropping back on the throttle will not only let you enjoy the Bf.110 at a more scale

pace, it will also result in longer flight times, reduce the risk of the motors and

ESC’s over heating in hot weather and increase the life of your flight pack.

3. Flight packs of 25C dischrage rate or above are recommended for use in the Bf.110

to ensure optimal performance in flight.

4. Keep all leads within the fuselage area (under the battery hatch) as tidy as possible.

Following closely the slender lines of the original means there is not a great deal of

space in this area and tidy wires not only looks better but also allows the canopy to

attach fully whilst allowing air to pass around the internal electronics.

5. Inspect the propeller blade mounting nut/bolts frequently, especially if you’ve

suffered a hard landing or the prop has been knocked. The blades can come out of

alignment if forced, so it is important to maintain an equal distance between all

three blades to avoid any unwanted vibration or a drop in efficency. Keep them tight!

6. When the Bf.110 is not in use, it is recommended that it is stored with the landing

gear in the retracted position. This will prevent the gear door springs from stretching

and thus improve the operational life of the system.

Thank you again for purchasing the Durafly Messerschmitt Bf.110.

We hope you’ll have many happy days of dog fighting with other Durafly

warbirds and straffing runs down the strip ahead of you.

Don't forget, spare parts are available for this model,
