Dear fellow-modeller,

Congratulations on your purchase of the robbe

Flitework Midi Corsair; the full-size machine

was the ﬁrst aircraft ever to be operated by the

Flying Bulls. We also wish to thank you for the

trust you have shown in us by purchasing this

model, and hope you have many enjoyable

hours building and ﬂying the robbe Flitework

Midi Corsair.

CAUTION!

Radio-controlled model aircraft are not toys! A

high level of technical expertise and modelling

experience are required to complete, ﬂy and

maintain this model aeroplane. Handling the

model and its technical equipment carelessly

or incorrectly may result in serious personal

injury and property damage.

Building and Operating Instructions - Corsair ARF No. FW004006

Be sure to read these Safety Notes before

you assemble your model. Always keep to

the procedures and settings recommended

in the instructions.

If you are operating a radio-controlled model

aircraft, helicopter, car or boat for the ﬁrst

time, we recommend that you enlist an expe-

rienced modeller to help you.

Safety Notes

Radio-controlled models are not toys in the usual

sense of the term. Young persons under four-

teen years should only be allowed to operate

them under the supervision of an adult.

Building and operating these models requires

technical expertise, manual skills, a careful atti-

tude and safety-conscious behaviour.

Errors, negligence and omissions in building or

ﬂying these models can result in serious perso-

nal injury and damage to property.

Since the manufacturer and vendor are not in a

position to check that your models are built and

operated correctly, all we can do is bring these

hazards expressly to your attention. We deny all

further liability.

Aircraft propellers, and all moving

parts generally, constitute a constant

injury hazard.

It is essential to avoid touching such

parts.

Please bear in mind that motors and

speed controllers may become hot

when operating.

It is essential to avoid touching such

parts.

Do not stand close to the hazard area

around rotating parts when an electric

motor is connected to the ﬂight battery.

You must also take care to keep all other

objects away from moving or rotating

parts.

Observe the instructions provided by

the battery manufacturer.

Overcharged or incorrectly charged

batteries may explode. Take care to

maintain correct polarity.

Ensure the equipment is protected from dust, dirt

and moisture contamination. Do not subject the

system to excessive heat, cold or vibration.

Use the recommended charger only, and charge

the batteries only for the prescribed period.

Check your equipment for damage at regular in-

tervals, and replace defective components with

genuine spare parts.

Do not re-use any devices which have been da-

maged in a crash or by water, even when they

have dried out again.

Either send the equipment to the robbe Service

Department for checking, or replace the parts in

question.

Crash or water damage can result in concealed

defects which may lead to failure in subsequent

use.

Use only those components and accessories

which we speciﬁcally recommend.

Do not carry out modiﬁcations to the radio con-

trol system components apart from those descri-

bed in the instructions.

Building and Operating Instructions - Corsair ARF No. FW004006

Operating the model

Never “point” the transmitter aerial straight at the

model when operating it. The transmitter signal

is at its weakest in this direction. It is always best

to stand with the long side of the aerial angled

towards the model.

Insurance

Ground-based models are usually covered by

standard personal third-party insurance policies.

In order to ﬂy model aircraft you will need to ex-

tend the cover of your existing policy, or take out

speciﬁc insurance.

Check your insurance policy and take out

new cover where necessary.

Liability Exclusion

robbe Modellsport is unable to ensure that you

observe the assembly and operating instruc-

tions, or the conditions and methods used for

installing, operating and maintaining the model

components.

For this reason we accept no liability for loss, da-

mage or costs which are due to the erroneous

use and operation of our products, or are con-

nected with such operation in any way.

Regardless of the legal argument employed, our

obligation to pay compensation is limited to the

invoice value of those robbe products directly

involved in the event in which the damage oc-

curred, unless otherwise prescribed by law. This

does not apply if the company is deemed to have

unlimited liability according to statutory regulati-

on due to deliberate or gross negligence.

No. FW004006

1. Installing the elevator and rudder horns (Figs. 1 and 2)

The horns and spreader plates can be glued in place initially using robbe Speed Foam,

before they are fixed permanently using the screws supplied in the kit. Always sand the

plastic parts before gluing, and remove all traces of grease beforehand. This method saves

you the awkward task of holding the small plastic parts, and allows you to concentrate on

tightening the screws just to the correct extent, i.e. without deforming the moulded foam

part. Use the shorter screws for the elevators.

Please use the four long plastic screws for the rudder horn.

2. Joining the wing panels (Figs. 3 and 4)

All the joint surfaces must be sanded carefully before the wing panels are glued together,

with the aim of removing almost all the blue paint. As adhesive we recommend Ropoxi

5-minute epoxy thickened with micro-balloons. Apply the adhesive to the joint surfaces,

push the wings together, and screw them to the fuselage while the epoxy is curing. Wipe

off excess resin with a cotton bud or similar.

3. Installing the aileron and landing ﬂap horns

The aileron and ﬂap horns are ﬁtted and screwed in place using a similar procedure to that

described in Point 1. Use four shorter screws (2 x 15 mm) for the landing ﬂaps. For the

aileron horns use the longer plastic screws (1.8 x 20 mm) towards the nose of the aircraft.

Building and Operating Instructions - Corsair ARF No. FW004006

4. Gluing the tailplane to the fuselage (Fig. 5)

The tailplane should be glued to the fuselage using a similar procedure to the wings. Sand

all joint surfaces thoroughly before applying glue.

Glue the tailplane unit to the fuselage using Ropoxi 5-minute epoxy, and pin it in place.

Do not use adhesive tape to hold the parts together while the glue is drying, as it may tear

the paint from the EPO foam when peeled off again.

5. Gluing the fin to the fuselage (Fig.6)

Sand the joint surface of the fin thoroughly to expose the white EPO foam. Apply a very

thin coat of glue to the joint surfaces, to avoid excess glue being squeezed out of the joint

and into the retract unit below it, where it could jam the spindle or mechanism. Insert the

fin as far as it will go, then pull it back by 1 mm.

Pin the fin in place until the epoxy has set hard.

Building and Operating Instructions - Corsair ARF No. FW004006

6. Wiring the RC system components and the retract units (Figs.7 and 8)

The seven-way central connector represents the core interface between the fuselage and

the wings. Ensure that the central connectors fit together snugly and lock mechanically.

The flap servos are linked together to a single 3-pin RC connector, and must be connected

separately to receiver channel 6. If you intend to remove the wing every time you transport

the model, we recommend the use of a 200 mm servo extension lead (Order No. 4644) for

connecting the flap servo lead. The wing can now be screwed to the fuselage.

Check that no wires are caught between the fuselage and the wing when the model is

rigged. Connect the leads to the receiver in accordance with the cable numbers.

Please note that there are differences in channel sequence from one RC system to ano-

ther. The cable numbers are correct for Futaba equipment.

Cable assignment:

1 - Aileron

2 - Elevator

3 - Speed controller

4 - Rudder

5 - Retractable undercarriage

6 - Landing ﬂaps

Please check carefully that all the RC components respond correctly to the controls, and

work as expected. If you are using a Futaba radio control system you will need to reverse

the throttle channel before operating the model for the ﬁrst time.

Building and Operating Instructions - Corsair ARF No. FW004006

8. Connecting and adjusting the control surface linkages, travels

a) Connecting the rudder pushrod (Fig. 9):

Set the servo to neutral (centre) and screw the clevis onto the pushrod, holding the push-

rod tightly in a pair of pliers. When the pushrod is the correct length, connect the clevis to

the outermost hole in the rudder horn. The rudder should now be at centre. The correct

rudder travel is about 20°.

b) Connecting the elevator pushrod (Fig. 10):

Move the elevators up and down repeatedly to ease the hinges, but don't over-stress them:

the elevators should move relatively easily over a range of +/- 20°. Screw the two elevator

clevises onto the pushrod, and adjust them so that both elevators are exactly at neutral.

You may wish to loosen the clamp behind the elevator servo, set the correct elevator

neutral position, and then re-tighten the screw in the clamp. If the elevator servo moves

excessively in the mount, the elevator hinges are still too stiff.

c) Connecting the aileron pushrods:

Use the same procedure as described for the other linkages. You may need to open up

the outermost hole in the servo output arm to 1.2 mm using a piece of steel rod heated

in a match-ﬂame. Set the aileron servos to centre from the transmitter, then connect the

pushrod to the outermost hole in the servo output arm, and the second hole from the

outside of the aileron horn. Screw the clevis in or out to set the aileron exactly to centre.

Travel: +/- 20°

Building and Operating Instructions - Corsair ARF No. FW004006

d. Connecting the flap linkages (Fig. 11):

When installing the flap linkages please ensure that maximum down-travel is possible.

Use your transmitter to program the servo end-points in such a way that none of the servos

strikes its end-stop in either direction, as this causes very high currents to flow. To obtain

the optimum travel, connect the pushrod to the outermost hole in the servo output arm, and

to the innermost hole in the flap horn.

9. Assembling / Installing the propeller (Fig. 12):

For safety reasons the propeller should not be fitted until you have completed the adjust-

ments to the control surfaces. This ensures that no damage or injury will result if the motor

should burst into life accidentally during the set-up procedure.

Fit the propeller between the two chrome-plated dummy hub components and tighten the

M6 nut. Cautiously tighten the nut with a 10 mm spanner. The black spinner cap can now

be screwed in place.

Building and Operating Instructions - Corsair ARF No. FW004006

10. Before the ﬁrst ﬂight:

The Centre of Gravity will automatically be correct if you install the 4S 2650 mAh ﬂight battery in the compartment and slide it towards the

fuselage nose, where it will be held in place by the lug on the canopy.

Check carefully that all the control surfaces deﬂect in the correct direction in response to the appropriate stick. Check the operation of

the retractable undercarriage and ﬂaps.

We recommend assigning the retract system and the ﬂaps to a single three-position switch with the following functions:

Position 0: ﬂaps retracted, undercarriage retracted

Position 1: ﬂaps retracted, undercarriage extended

Position 2: ﬂaps lowered, undercarriage extended

10. The ﬁrst ﬂight:

Ensure that the battery is fully charged, and carry out a complete check of the control surface functions. Allow the model to accelerate

steadily on the runway, using the rudder to keep it on a straight heading. on long grass you may ﬁnd that slight up-elevator is required in

the early stage of the ground-roll to prevent the model tipping forward onto its nose.

The aeroplane is very good-natured during the landing approach, and with the ﬂaps lowered it can be brought in to land slowly at a fairly

steep approach angle. The ﬂaps are not intended to increase aerodynamic lift, but just to reduce the model's

airspeed.

Building and Operating Instructions - Corsair ARF No. FW004006

11. Test-flying, flying notes

- Do not allow persons or loose objects, such as rags, tools or similar, in front of the model. Caution: whenever you are working

on the power system (for installation, set-up or maintenance), keep well clear of the rotational plane of the propeller - injury

hazard!

- For your first few flights it is best to wait for a day with no more than a gentle breeze.

- A good flying site consists of a tarmac runway or a large, flat, closely-mown grass field, devoid of trees, fences, high-tension overhead

cables etc.

- Repeat the check of all the working systems.

- The model should be taken off from the ground – it must always be launched directly into any wind.

- Carry out a series of taxi tests to become accustomed to the model's ground handling and response to the control surfaces.

- With the nose pointing straight into wind, apply full-throttle and allow the Corsair to pick up speed. When flying speed is reached, lift off

with a brief application of up-elevator.

- Keep the model flying straight and level at first; don’t initiate a turn while it is still close to the ground.

- Adjust the control surface trims if necessary, so that the model flies straight with a reasonable rate of climb “hands off”.

- Check the model's response to control commands. You may need to increase or reduce the control surface travels after the first landing.

- The stated control throws are just a guide for the first few flights. Every pilot should adjust the settings carefully to meet his personal

preferences.

Building and Operating Instructions - Corsair ARF No. FW004006

- Check the machine's stalling speed at a safe height. Keep the model's speed well above the stall for the landing approach.

- If you needed to adjust the trims during the test-flight, correct the length of the appropriate pushrod once the model is back on the ground,

then return the transmitter trims to centre so that full trim travel is available to both sides of neutral for subsequent flights.

Caution:

Stopping (obstructing) the motor when it is turning can cause serious damage to the mechanical system, and may even result in a

ﬁre. If the propeller is forcibly stopped, immediately move the throttle stick back to Idle!

Note re. the ﬂight battery:

As soon as you notice a reduction in motor power, land immediately and disconnect the battery. Never continue ﬂying until the

battery is ﬂat, as this causes a deep-discharge condition which results in permanent damage. Allow the battery to cool down before

recharging it.

Replacing the propeller:

A damaged propeller must be replaced immediately.

Building and Operating Instructions - Corsair ARF No. FW004006

Corsair ARF power unit

Technical specification, 40 A speed controller:

Continuous current: 40 A

Peak current: 55 A, (max. 10 seconds)

BEC mode: Linear

BEC output: 5V / 3A

LiPo cell count: 2-4

Low voltage protection: yes

Dimensions (speed controller): 68 x 25 x 8 mm

Weight: 35 g

VERY IMPORTANT: since different transmitters feature different throttle

settings, we strongly advise you to use the "Throttle range set-up function" to

calibrate the throttle range.

Caution: this controller is not protected against reversed polarity.

Connecting a battery to the controller's terminals with reversed polarity

will instantly destroy the unit.

If you prefer to use a separate receiver battery instead of the

BEC system, you must withdraw the red wire from the receiver

lead attached to the controller, and insulate the bare end to avoid short-circuits.

Using the controller for the first time:

Move the throttle stick to the Stop position, then switch the transmitter on.

Connect the flight battery to the speed controller, special beep sequence "123".

You will hear the following according to the selected battery type:

Beep, beep, beep, beep for detected 4S LiPo battery. At the end a long beep

---- is emitted: the speed controller is now ready for use.

Move throttle stick forward: motor starts.

Setting the full-throttle and stop positions:

(if the transmitter is new, the throttle range should always be re-calibrated)

Switch transmitter on, move throttle stick to full-throttle position.

Connect battery to speed controller.

"Beep-Beep" sequence sounds, indicating that the upper throttle position

stop has been correctly confirmed. Move the throttle stick to the desired Stop

position.

"Beep-Beep" sequence sounds again, indicating that the Stop position has been

correctly confirmed. Finally a long beep will sound.------. The speed controller is now

ready for use.

Note: When programming the Stop position, you will hear a series of short

sequential beeps heard followed by 2 short beeps if the throttle stick is at the

wrong end of its travel.

Protective functions

1. Start-up guard: if the motor does not start within two seconds of the

throttle command, the speed controller switches off the output voltage. If

this should happen, you MUST move the throttle stick fully back before

the motor will start. Failure to start may be due to the following reasons:

intermittent connection between speed controller and motor; the propeller

or the motor is jammed; the gearbox is damaged, etc.

2. Overheating protection: if the controller's temperature rises above 110°C,

the unit reduces the output voltage.

3. Throttle signal failure protection: if the throttle signal is absent for one

second, the controller reduces the output voltage. If a further failure occurs

for two seconds, the controller switches off the output voltage completely.

Description of functions:

1. Setting the brake: Brake: ON / OFF. Preset = Brake OFF

2. Battery type: Li-xx (Li-Ion or Li-Poly) = Li-xx.

3. Low voltage cut-off mode. Soft (power reduced) or hard (full cut-off).

Default = reduced power

4. Low voltage cut-off: Low / medium / high. Default = Medium 1) For

Li-Ion / LiPo batteries, the cell-count is automatically recognised. Cut-off

voltage low / medium / high at:

2.85 V / 3.15 V / 3.3 V. e.g.: medium cut-off voltage with 3 LiPo cells:

3.15 x 3=9.45 V. 2).

5. Start-up / Power-on mode: Normal / Soft / Super-soft, Default = Nor-

mal Normal is suitable for ﬁxed-wing model aircraft. The start-up speed

at the soft / super-soft settings is fairly slow at one second (soft start)

/ two seconds (super-soft start) measured from start-up to full-throttle.

If the throttle is closed (throttle stick moved back to Idle) then opened

again (throttle stick advanced) within three seconds of initial start-up,

the controller switches automatically to Normal mode in order to prevent

crashes due to retarded throttle response.

6. Timing: Low / medium / high, default = low.

Low timing can be selected for most motors. For high power we

recommend low timing for two-pole motors, and medium timing for

motors with six or more poles. For higher rotational speeds the High

timing setting can be used. Caution: setting the timing too high

can cause problems!

Programming:

1. Start programming mode:

1) Switch transmitter on, move throttle stick fully forward, then connect

battery

2) Wait 2 seconds, then “beep-beep” sound should be emitted

3) Wait a further 5 seconds, then the special sound "56789" should be

emitted: this means that programming mode has started.

2. Select menu:

In programming mode, you will hear eight beep sequences. If you move

the throttle stick to the Stop position and hear a tone sequence within 3

seconds, then the appropriate set-up menu has been selected.

1) “beep” Brake (1 short beep)

2) “beep-beep-” Battery type (2 short beeps)

3) “beep-beep-beep-” Cut-off mode (3 short beeps)

4) “beep-beep-beep-beep-” Cut-off voltage (4 short beeps)

5) “beep-----” Start-up mode (1 long beep)

6) “beep-----beep-” Timing (1 long, 1 short beep)

7) “beep-----beep-beep-“ Default setting (1 long, 2 short beeps)

8) “beep-----beep-----” Interruption (2 long beeps)

3. Select settings:

You will hear sequences of beeps. Move the throttle stick forward

to conﬁrm your desired value in accordance with the sequence of

beeps. You will then hear the special beep "1515"; this conﬁrms and

stores the value. (leave throttle stick forward, then Point 2) and you

can select and alter additional menu points.

Building and Operating Instructions - Corsair ARF No. FW004006

4. Concluding programming mode

(2 options):

1) When you hear the special tone “1515 ” move

the throttle channel to Idle within 2 seconds.

2) When you hear the sequence "beep----beep----"

move the throttle stick back to Idle within 3 se-

conds.
