=== Introduction ===
Congratulations on your purchase of the semi-scale model of the Swift S-1 aerobatic glider. You are about to start the assembly of a model manufactured from virtually unbreakable expanded polyolefin (EPO) foam powered by a mighty brushless motor and lightweight LiPo battery. Everybody who has already mastered flying a "full house" trainer – with aileron, elevator, rudder, and throttle control – will enjoy this beautiful high–performance glider.

===Swift S–1: a Polish aerobatic champion===
By the end of the 1980s, the Margański & Mysłowski Zakłady Lotnicze decided there was a "gap" in the aerobatic glider market – apparently the good old all–wooden SZD–21–2b Kobuz 3 designed back in the 1950s was no more the "hot stuff". So in 1991 designers Edward Margański and Jerzy Cisowski backed by Jerzy Makula (then triple world aerobatic glider champion) came with a new Swift S–1, a modern all–composite aerobatic glider with an incredible 4 seconds roll rate capable of handling +/-10 g. The reward followed almost immediately – Jerzy Makula won his fourth FAI World Glider Aerobatic Championships the same year!

=== Before you start === <!--T:3-->

<!--T:4-->
# 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.
# 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.
# 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.
# 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.
# 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! Later you can fine-tune the CG position to suit your flying style and skills.

=== Safety precautions and warnings === <!--T:10-->

<!--T:11-->
* 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 following 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 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. This interference can cause momentary 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. It may not be exposed to higher temperatures otherwise severe distortion of the foam airframe or other damage may occur.

=== Model assembly === <!--T:17-->

<!--T:18-->
# Connect the elevator servo cable to the corresponding extension cable in the fuselage. Use a shrinking tube or strip of sticky tape to secure the connectors from disconnecting during flight. '''(Fig. 1)'''
# Secure the horizontal stabilizer with two M3×10 mm screws. '''(Fig. 2)'''
# Attach the rudder to the fin and snap the rudder hinges in place. '''(Fig. 3)'''
# Connect the rudder servo linkage to the rudder arm. '''(Fig. 4)'''
# Connect the aileron servo cables to the corresponding extension cables in the wing opening in the fuselage. '''(Fig. 5)'''
# Insert the wing halves into the fuselage and secure with the M6 nylon bolt. '''(Fig. 6)''' Your Swift S1 is fitted for the belly landing as supplied; you might wish to add the undercarriage.
# Remove the screw and the foam filler from the landing wheel bay. '''(Fig. 7)'''
# Install the wheel yoke using the same screw into the wheel bay. '''(Fig. 8)'''
# Insert the wheel into the yoke, attach the dummy undercarriage doors from both sides of the yoke and secure with two screws. '''(Fig. 9)'''
# The flight pack is to be placed in the bay in the centre of the cockpit; use Hook–and–loop ties to fasten it. You can place your receiver (secured with a strip of Hook–and–loop or double-sided foam tape) behind the flight pack; the ESC is to be secured by the same along the flight pack. Connect servos and your ESC to the receiver; deploy the antennas so their active parts are square to each other (if you are using a receiver featuring the diversity antennas). With your radio on, set the servos to the neutral position (sticks and trims centred) and fasten the setting screws of the pushrod connectors on the elevator and rudder servo arms. Perform the throttle range calibration of the ESC as described in the attachment of this manual. '''(Fig. 10+11)'''
# Attach the canopy.
{{Note|type=info|text='''Note:''' The kit is supplied with a Y-cable for ailerons so you can use even the most basic 4-channel radios to control your Swift S1. If you intend to use independent control of aileron servos and an advanced computer radio, you will have to replace the default Y-cable with two 25–30 cm extension cables.}}

=== RC set installation and preflight check === <!--T:19-->

<!--T:20-->
* Referring to the instruction manual of your radio carefully hook up the onboard electronics.
* Once everything has been correctly connected, turn on your transmitter and plug in the flight pack. Check the neutral positions and throws of all control surfaces. If you need to make the control surface throws smaller, simply move the pushrod closer to the centre on the servo arm or move it far from the control surface on the control horn. And vice versa.

* The "Low Rate" recommended control surface throws are suitable for a less skilled pilot and regular soaring. The "High Rate" setting allows an experienced pilot to explore the full capabilities of his model. The aileron differential (aileron down deflection reduced to 50 % of up deflection) is only possible with a computer radio.

<!--T:23-->
* Check the direction of rotation of the propeller. If it is incorrect, simply swap any two of the three wires between the ESC and motor or program the ESC (refer to the ESC manual).
* Check the correct position of the centre of gravity (CG): 65–70 mm behind the leading edge of the wing '''(Fig. 12)'''. Adjust the CG position by moving the flight pack – if you cannot reach the recommended position, do not hesitate to add an appropriate amount of lead to the nose or tail. An extra couple of grams won’t spoil the flying characteristics - but the incorrect CG position is a killer.
* Fully charge your flight pack and transmitter batteries, check the proper function of your radio and perform the range check of your radio according to its instruction manual. The range has to be almost the same with the motor off and at full throttle (no more than a 10 % decrease is acceptable). DO NOT try to fly unless the range check is 100% successful.

=== Flying ===
The test-flying and fine-tuning are pretty much straightforward, there will be no surprise for a medium-advanced pilot who is supposed to fly this model.
