It really is essential to read and observe the special safety notes included in these operating in­structions and the appendix. If you ever dispose of the model, please be sure to pass on the complete operating instructions to the new owner.
Introduction
The Graupner/SJ HoTT DELUXE is a particularly attractive RC model aircraft which offers a superb performance in the air. The HoTT DELUXE is equipped as standard with an HPD brushless power system. The motor is very powerful, and gives the HoTT DELUXE an outstanding climb rate and excellent aerobatic qualities. The model is based loosely on a luxury-class light aircraft, and features radio aerials and stabiliser vanes on the fin. Please take the time to read right through these operating instructions before attempting to operate the model.

Essential tools and adhesives (not included)
Cyano-acrylate glue (“cyano”) Order No.5821 Cyano-acrylate activator Order No.953.150 You will also need the following: abrasive paper, 1.5 mm A/F allen key, screwdriver.
Assembling the model
The airframe requires just a few glued joints and assembly steps to complete, but the following instructions must still be observed carefully to ensure that the model flies safely. The first step is to open the canopy: grasp it firmly at the rear end, and pull it upwards and off. Now use a servo tester or your radio control system to centre the rudder and elevator servos.
The photo shows the fuselage with the tailplane and fin inserted. Push the panels into their slots as far as they will go, set them exactly “square”, and slip the pushrods through the swivel connectors. When you are satisfied, apply low-viscosity cyano­acrylate (“thin cyano”) along the joints. Caution: do not use activator for these
joints, as this will prevent the adhesive running fully into the joints.
Allow the glue to set hard, then tighten the grubscrews in the swivel connectors using the 1.5 mm A/F allen key. Ensure that both elevator panels are exactly parallel and at neutral (centre).
Caution: after tightening the grubscrews check that the pushrods are securely fixed. If either of them should work loose, the model is likely to crash.

Fit the propeller on the motor shaft as shown in the picture: the clamping screw must engage on the machined flat in the shaft. Tighten the clamping screw firmly using the allen key. This completes work on the fuselage.
The next step is to glue the four plywood parts in place as shown. It is essen­tial to sand the joint surface of all four rectangles to obtain really strong glued joints. Glue the rectangular plywood plates to one wing panel to act as guides. The
wing panels can now be glued together: apply glue to the whole of the contact area. Do not use activator, otherwise you may not have enough time to align the two wing panels relative to each other before the glue sets.

Caution: it is essential to wear protective goggles when completing this pro­cedure, as glue may be forced out of the joints when the plywood plates are pressed into place.
Glue the two wing joiners in place: apply glue to the slot, then immediately press the joiner fully into place; don’t use activator. If excess glue is forced out of the joints, wipe it off immediately using a piece of paper towel.
Wing assembly is completed by gluing in place the spreader washers for the wing retainer screws, and removing the excess foam which provides protection against transport damage. The wing can now be screwed to the underside of the fuselage. Remember to route the servo leads through the bottom opening in the fuselage.
Please bear in mind that connecting the G 3.5 plug and socket, as shown in the photo, switches the receiver on. In this state the motor could suddenly burst into life as a result of unpredictable circumstances; this is potentially very dangerous. For this reason it is essential to avoid touching the propeller when the G 3.5 plug and socket are connected, and to keep the propeller away from all objects. Pierce a hole in the right-hand fuselage side for the receiver aerial.
Connect the servo leads and the speed controller to the receiver in the following sequence: speed controller to socket 1, left-hand aileron servo to socket 2, elevator servo to socket 3, rudder servo to socket 4, right-hand aileron servo to socket 5.
Caution: refer to the diagram printed on the receiver to ensure that the con­nectors are plugged in the right way round; the brown or black wire must always be at the top of the receiver.

Cut out the individual decals from the transfer sheet, and apply them to the model in the arrangement shown in the drawing. Note that the decals must be slit along the control surface hinge lines, otherwise the control surfaces will jam. The windscreen is supplied in three parts so that it can be applied to the model without creases.
Control surface travels
The model is designed to produce the correct control surface deflections when servo travel is set to the default value of about 100%. The actual values are as follows, in

each case measured at the trailing edge and inboard end of the control surface: rudder approx. 15 mm each way, elevator approx. 12 mm up and down, ailerons approx. 15 mm up and approx. 7 mm down.
Centre of Gravity range
The HoTT DELUXE should balance at a point between 70 and 80 mm aft of the root leading edge of the wing. If you have fitted the recommended LiPo battery, the CG will automatically be in this range without the need for ballast. It is a good idea to check the model’s CG by supporting it under the wing on two fingertips at the recom­mended point: the model should now balance level.
The photo shows the CG range, as measured from the wing root leading edge.
First flight
First give the LiPo and transmitter batteries a full charge. It is important to use the recommended chargers exclusively, and to observe the operating instruc­tions and safety notes supplied with the charger.
Wait for a day with no more than a light breeze, and prepare the model fully. It should be given a fairly brisk hand-launch directly into the wind; trotting forward for a few paces gives the right launch speed. The model’s nose should be inclined up by about 15° when it leaves the launcher’s hand. It is essential to adjust the model’s trim carefully, especially during the first flight: this is accomplished by moving the trim buttons below and to one side of the primary sticks. Adjust the aileron trim button until the model flies perfectly straight. Always land directly into wind, with the motor switched off. Gently apply up-elevator to flare out and reduce speed just before the model touches down. It is essential always to land directly into wind. Note: the model can be fitted at any time with an under­carriage; all the parts required for this are included in the set, Order No. 9932.5. The cowl is only secured with double-sided tape. If you need access for maintenance work, slide a broad knife-blade into the separation line with the fuselage, and lift the cowl off.
Please note: for safety reasons it is essential to disconnect the G 3.5 plug and socket after every motor run; this also avoids damage to the LiPo battery.
All of us at GRAUPNER/SJ Modellbau hope you have many fine flights with your new HoTT DELUXE

Safety Notes
It is a legal requirement to obtain third-party insurance before you operate any model aircraft. Before attempting to operate the model for the first time it is essential to read right through the operating instructions attentively. You alone are responsible for the safe operation of your RC model aircraft. Young persons must be supervised by a responsible adult who is aware of the possible hazards involved in the operation of model aeroplanes.
In legal terms our models are classed as aircraft, and as such are subject to legal regulations and restrictions which must be observed at all times. It is important to use only those parts included in the kit, together with other genuine Graupner accessories and replacement parts as recommended expressly by us. Even if you change a single component, you can no longer be sure that the whole system will work reliably, and such changes also invalidate your guarantee.
Avoid short-circuits at all times. The high energy density of batteries involves a constant risk of explosion and fire.
A radio-controlled model aircraft can only work properly and fulfil your expectations if it is built very carefully, and in accordance with the building instructions. Nobody would climb into a full-size sailplane and try to fly it without first completing a course of training. Model flying is just such a skill, and has to be learned in exactly the same way.

However, as manufacturers we have no means of influencing the way you build and operate your RC model aircraft, and for this reason we can do no more than point out the hazards expressly. We accept no further liability. If you need help, please enlist the aid of an experienced modeller, join a model club or enrol at a model flying training school. Model shops and the specialist model press are also good sources of information. The best course is always to join a club and fly at the approved model flying site. The operator must be in full possession of his bodily and mental capabilities. As with car driving, it is not permissible to fly a model aircraft under the effect of alcohol or drugs.
Make sure that all passers-by and onlookers are aware of the hazards involved in the operation of your model. Remind spectators to keep a safe distance from the model.
Always maintain a safe distance between your model and other people or objects. Never fly low over people or directly towards them. Radio-controlled models should only be flown in “normal” weather conditions, i.e. a temperature range of -5° to +35°C. More extreme temperatur es can lead to changes in battery capacity, material characteristics, the strength of glued joints and other unwanted effects. All model flyers should behave in a way which minimises the danger to people and property. Never act in any manner which will disturb other pilots, or have an adverse effect on safe, orderly flying at the site. Don’t operate your model aeroplane in the vicinity of overhead power cables, industrial sites, residential areas, public roads, school playgrounds or sports fields etc.
Pre-flight checks Check that the radio control system works correctly and at full range before every flight: switch on the transmitter and receiving system, and ensure that all the control surfaces work smoothly, and deflect in the correct “sense” in relation to the stick movements. If you are a beginner to this type of model flying, we recommend that you enlist an experienced model pilot to help you check and test-fly the model.
Please don’t ignore our warnings. They refer to hazardous materials and processes which, if ignored, can result in fatal injury or serious damage to property.
Propellers powered by a motor constitute a permanent hazard and represent a real risk of injury. Don’t touch them with any part of your body. For example, a rotor spinning at high speed can easily cut your finger badly.
Keep well clear of the rotational plane of the propeller. You never know when some part or the whole prop may come loose and fly off at high speed, hitting you or anybody else in the vicinity. In unfavourable circumstances this could result in serious injury. Ensure that the revolving propeller never comes into contact with any object.
Make sure that it is impossible for any object to stall or block the propeller. Every time you intend to operate your model, check carefully that it and everything attached to
it (e.g. propeller, tailplane etc.) is in good condition and undamaged. If you find a fault, do not fly the model until you have corrected it.
Radio interference caused by unknown sources can occur at any time without warning. If this should happen, your model will be uncontrollable and completely unpredictable. Never leave your radio control system unguarded, as other people might pick it up and try to use it. Do not switch the electric motor on unless you have checked that there is nothing in the rotational plane of the propeller. Never attempt to stop the propeller when it is spinning. Electric motors with propellers attached must only be run when firmly mounted. If you are to fly your model safely and avoid problems, it is essential that you are aware of its position and attitude throughout each flight - so don’t let it fly too far away. If you detect a control problem or interference during a flight, immediately land the model to prevent a

potential accident. Model aeroplanes must always give way to full-size aircraft. Take-off and landing strips should be kept free of people and other obstacles. Your HoTT COMPUTER RC system can only work reliably if the batteries are kept fully charged. Never use hot, faulty or damaged batteries. It is important to observe the instructions supplied by the battery manufacturer.
Please don’t misunderstand the purpose of these notes. We only want to make you aware of the many dangers and hazards which can arise if you lack knowledge and experience, or work carelessly or irresponsibly. Provided that you take reasonable care, model flying is a highly creative, instructive, enjoyable and relaxing pastime.
