Before you start

1. If you are not an experienced RC pilot, plan to have a fully competent pilot check your completed model and help you with your first flights. Even though we have tried to provide you with a thorough instruction manual, RC models are rather complicated and an experienced modeller can quickly check over your model to make sure your first flights are successful.
2. Please assemble your model exactly according to these instructions. Do not attempt to modify or change your model in any way, as doing so may adversely change its flying characteristics.
3. Before you begin, please check the entire contents of this kit to make sure that no parts are missing or damaged. This will also help you to become familiar with each component of your plane. If you find that any of the parts are either missing or damaged, please contact your dealer immediately for replacement.
4. Trial fit each part before glueing it in place. Make sure you are using the correct part and that it fits well before assembling. No amount of glue can make up for a poorly-fitting part.
5. The manual contains a drawing showing the default position of the Centre of Gravity (CG) and recommended control surface throws. Please note it is essential to keep the recommended CG position for the first flight otherwise the model could be unstable, hard to control or even unable to fly at all! Start at the forward end of the specified range for greater stability. A rearward CG makes the model more responsive and less stable; adjust it only after becoming familiar with the model, keeping within the specified range.

Note

Your dealer cannot accept kits for return if construction has begun.

Safety precautions

This RC model is not a toy. Use it with care and strictly following the instructions in this manual.

Assemble this model following strictly these instructions. DO NOT modify or alter the model. Failure to do so, the warranty will lapse automatically. Follow the instructions to obtain a safe and solid model at the end of the assembly.

Children under the age of 14 must operate the model under the supervision of an adult.

Assure that the model is in perfect condition before every flight, taking care that all the equipment works correctly and that the model is undamaged in its structure.

Fly only on days with a light breeze and in a safe place away from any obstacles.

General warnings

• An RC aeroplane is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only in a safe place and follow all instructions and recommendations in this manual. Beware of the propeller! Keep loose items that can get entangled in the propeller away from the spinning propeller, including loose clothing, or other objects such as pencils and screwdrivers. Ensure that your and other people's hands and faces, and animals are kept away from the rotating propeller.
• As the user of this product, you are solely responsible for operating it in a manner that does not endanger yourself and others or result in damage to the product or the property of others. This model is controlled by a radio signal that is subject to interference from many sources outside your control. Interference, equipment failure or pilot error can cause loss of control, so it is advisable to always keep a safe distance in all directions around your model, as this margin will help to avoid collisions or injury.
• Never operate your model with low transmitter batteries.
• Always operate your model in an open area away from power lines, cars, traffic or people. Avoid operating your model in populated areas where injury or damage can occur.
• Carefully follow the directions and warnings for this and any optional support equipment (chargers, rechargeable batteries, etc.) which you use.
• Keep all chemicals, small parts and anything electrical out of the reach of children.
• Moisture causes damage to electronics. Avoid water exposure to all equipment not specifically designed and protected for this purpose.
• The model is mostly made of plastics – it is not fireproof. Keep it away from heat sources, direct sunlight and hot enclosed cars; high temperatures can distort the foam airframe or cause other damage.
• Disconnect the flight battery whenever the model is not in use. Even at zero throttle, the ESC draws current; leaving the battery connected for hours or days can deeply discharge it, damage it and create a fire risk.

Model assembly

Danger

Remove the propeller before the initial radio, ESC and motor setup, including throttle calibration. Refit it only after confirming correct operation, with the flight battery disconnected. Keep the throttle at minimum during control-surface checks; centre only the aileron, elevator and rudder controls and their trims.

1. Slide both horizontal-tailplane halves onto the carbon joiner inserted through the fin. Secure them with four M2.5×8 mm socket-head screws. Attach the elevator pushrod ball link to the ball on the elevator horn. (Fig. 1)+(Fig. 2)+(Fig. 3)
2. Connect the wing multi-connectors to the corresponding sockets in the wing halves. Insert both wing halves fully into the fuselage until they click into place, then secure the wing with one M6×40 mm nylon screw. (Fig. 4)+(Fig. 5)
3. Connect the receiver, servos and ESC according to the wiring diagram. Secure the receiver at the rear of the cockpit with hook-and-loop tape or double-sided foam tape. With a diversity receiver, arrange the active antenna sections perpendicular to each other. Connections marked × in the diagram are not used on this model. (Fig. 8)
4. Secure the flight battery in the central cockpit bay with the installed hook-and-loop straps. Switch on the transmitter with the throttle at minimum, then connect the battery. Calibrate the throttle range according to the KAVAN Plus ESC instructions, with the propeller removed. Keep the throttle at minimum, centre the other controls and trims, and tighten the pushrod-connector screws on the elevator and rudder servo arms with the surfaces neutral. (Fig. 6)
5. Fit the canopy.

Note

The supplied connection board links the aileron, flap, elevator and rudder servos and the ESC to the receiver, allowing basic control with a 6-channel radio. For independent aileron and flap control with a suitable computer radio, bypass the board for these servos using a pair of wing adaptor cables, then assign and program the separate receiver channels. Independent control is required for the differential and advanced mixes described below.

Pre-flight preparation

Radio and control surfaces

Follow your radio instructions for installation and programming. With the propeller removed, switch on the transmitter at minimum throttle and then connect the flight battery. Check the neutral position, direction and travel of every control surface. To reduce travel mechanically, move the linkage closer to the servo-arm centre or farther from the control-surface hinge on its horn; reverse these changes to increase travel.

Control throws

Control surface	Low rate	High rate
Ailerons	20 mm up / 10 mm down	25 mm up / 13 mm down
Ailerons (Butterfly)	20 mm up	20 mm up
Ailerons (Thermal)	3 mm down	3 mm down
Ailerons (Speed)	3 mm up	3 mm up
Elevator	±10 mm	±15 mm
Elevator (Butterfly)	1–3 mm down	1–3 mm down
Rudder	±30 mm	±40 mm
Flaps	12 mm up / 18 mm down	12 mm up / 18 mm down
Flaps as ailerons	7 mm up / 3.5 mm down	10 mm up / 5 mm down
Flaps (Butterfly)	30 mm down	30 mm down
Flaps (Thermal)	4 mm down	4 mm down
Flaps (Speed)	4 mm up	4 mm up

Use low rates for less experienced pilots and normal soaring. High rates allow an experienced pilot to use the model’s aerobatic capabilities. Aileron differential, with downward travel about 50 % of upward travel, requires a computer radio and independent aileron channels.

With suitable radio programming and independent wing-servo channels, the following mixes can be used:

• Butterfly airbrake: both ailerons move up and both flaps move down, with 1–3 mm of down-elevator compensation as listed in the table.
• Thermal: both ailerons and both flaps move down by the listed amounts.
• Speed: both ailerons and both flaps move up by the listed amounts.
• Flaps as ailerons: the flaps assist roll control, following the ailerons with the asymmetric travel shown in the table.

Motor rotation

Check rotation during the initial propeller-free test: the motor must turn clockwise when viewed from the cockpit towards the nose. If it turns the wrong way, return the throttle to minimum, disconnect the flight battery and swap any two of the three wires between the motor and ESC. Test again before fitting the propeller.

Centre of gravity

The CG must be 75–85 mm behind the wing leading edge, measured at the wing root as shown. Check with the model complete and its flight battery installed. Adjust the battery position first; if necessary, secure suitable ballast in the nose or tail. (Fig. 7)

Caution

Do not fly with the CG outside the specified range. Start at the forward end for the first flight; a rearward CG reduces stability. A small amount of securely fitted ballast is preferable to an incorrectly balanced model.

Range and final checks

Fully charge the flight and transmitter batteries. Check the complete radio installation and perform the range test specified by the radio manufacturer, both with the motor off and at full throttle. Restrain the model securely and keep everyone clear of the propeller and its rotation plane. The range at full throttle must not decrease by more than 10 % compared with the motor-off test. Do not fly unless both tests pass completely.

Flying

The Pulse 2200 V2 is intended for an intermediate pilot. If you lack experience with this type of model, have an experienced pilot make the first flight, check the trim and help with the initial flights. Choose light wind and a clear, safe flying site. Test flying and fine adjustment follow normal practice for a thermal motor glider of this size and layout.

Appendix

KAVAN R-50SB Plus instructions

Use the KAVAN Plus ESC instruction manual for throttle calibration, normal startup, programming, protection functions and troubleshooting. Select LiPo battery mode for the specified flight battery and configure the motor brake for the folding propeller.

Caution

• Do not install the propeller on the motor when you test the ESC and motor for the first time to verify the correct settings on your radio. Only install your propeller after you have confirmed that the settings on your radio is correct.
• Never use ruptured or punctured battery cells.
• Never use battery packs that are known to overheat.
• Never short circuit battery or motor terminals.
• Always use proper insulation material for cable insulation.
• Always use proper cable connectors.
• Do not exceed the number of cells or servos specified for the ESC.
• Wrong battery polarity will damage the ESC and void the warranty.
• Install the ESC in a suitable location with adequate ventilation for cooling.
• Use only batteries that are supported by the ESC and ensure the correct polarity before connecting.
• Switch your transmitter ON first and ensure the throttle stick is in the minimum position before connecting the battery pack.
• Never switch your transmitter OFF while the battery is connected to your ESC.
• Only connect your battery pack just before flying and do not leave your battery pack connected after flying.
• Handle your model with extreme care once the battery pack is connected and keep away from the propeller at all times. Never stand in-line or directly in front of any rotating parts.
• Do not immerse the ESC under water, do not allow it to get wet while powered up.
• Always fly at a designated flying site and follow the rules and guidelines set by your modeller’s club.

Repairs and maintenance

• Please perform the range check in the beginning of each flying session.
• Before every take off please check the correct control surface movement.
• After every landing check the plane for any damage, loose clevises or push rods, damaged propeller etc. Do not fly again until the damage is repaired.

Although the Pulse 2200 V2 model is manufactured of the extra tough and virtually unbreakable expanded polyolefin (EPO) foam, damage or broken parts may occur. A minor damage can be repaired simply gluing the parts together with a cyanoacrylate (CA) glue or with a clear sticky tape. In a case of a major damage it is always better to purchase a brand new spare part. A wide range of genuine spare parts and accessories is available through the KAVAN Europe s.r.o. dealers.

In the unfortunate event of a crash or heavy landing, no matter how minor or major, you must lower the throttle stick to its lowest position as quickly as possible to prevent damage to the electronic speed controller.

Failure to lower the throttle stick and trim to the lowest possible positions in the event of a crash could result in damage to the ESC, which may require replacement of the ESC.

Note

Crash damage is not covered under warranty.
