MANY THANKS for deciding to purchase the Graupner/SJ HoTT 2.4 system. Please read right through these operating instructions before you attempt to install and operate the Graupner HoTT 2.4 system.

SAFETY NOTES Warning! The receiver must never be operated under the influence of medication, alcohol, drugs etc. Caution! Any deviation from the instructions may have an adverse effect on the function and operational security of the receiver, and must be avoided under all circumstances. Caution! The operator bears full responsibility for using the receiver. The only way to guard against personal injury and property damage is to handle the equipment carefully and use it exactly as recommended.
PAGE 4
1.2 GENERAL NOTES • The receiver’s integral gyros are very fast, high-resolution components. This means that you should always use high-speed digital servos wherever possible, so that the gyro’s corrective signals are converted directly and accurately into servo movement; this helps to prevent the model oscillating. • Keep all servo extension leads as short as possible.

personal injury. Read the operating instructions supplied with your radio control system for more details. The gyro system remains active in a fail-safe situation. 2.3 Range-checking The range of your Graupner/SJ HoTT 2.4 system can be checked as described in the following instructions. We recommend that you ask a friend to help you with the procedure. Ideally the receiver should already be bound to the transmitter. Install it in the model in its final position.

3. RECEIVER 3.1 Connections Connect the servos to the row of sockets on one end of the receiver. The connectors are polarised: note the small chamfers on one side. Never use force - the connectors should engage easily. The polarity is also printed on the receiver; the negative wire (-) is brown, the positive (+) red and the signal orange. The servo sockets of Graupner/SJ HoTT 2.4 receivers are numbered sequentially.
PAGE 7
PROGRAMMING THE GENERAL RECEIVER SETTINGS: The receiver can be programmed using a suitable HoTT transmitter or the SMART-BOX (Order No. 33700). RECEIVER 1.0 < > >ALARM VOLT: 3.8V ALARM TEMP: 70°C max altitude: 125m >Period: 10ms >SUMD at K6: No K5: SERVO LANGUAGE: english 3.2 RECEIVER SET-UP MENU The receiver set-up menu appears in the “Telemetry” menu under SETTINGS / DISPLAYS; alternatively - if you are using a SMART-BOX - under SETTING & DATAVIEW.

by “jittering” or “growling”. HoTT sum signal (SUMD): if you activate the digital sum signal at channel 6, a sum signal containing eight channels is present at this socket, instead of a servo signal. The HoTT receiver configured as SUMD constantly generates a digital sum signal from 8 control signals from the transmitter and makes this signal available at the appropriate servo socket, which is receiver-specific.
PAGE 9
Mixer ratio (TRAVEL-/+): in these two lines you can define the mixer ratio in relation to the source channel (FROM CHANNEL); the value is set separately for both directions.
PAGE 10
Only for transmitters without a butterfly (crow) mixer (e.g. mx-10 HoTT): If a butterfly (crow) mixer is required, you will not be able to use one of the two functions ‘differential’ or ‘landing flap’ adjustment, as two mixers are needed for this.
PAGE 11
• • • move the left wing down through at least 45°. This process defines the one axis and direction; now you must repeat the procedure for the other two axes. The gyro axis 1, 2 or 3 is now displayed in the ‘Aileron / Elevator / Rudder’ display; a negative prefix will appear if servo reverse is activated. Once all three axes are defined, the display automatically reverts to ‘New setting: no’.
PAGE 12
4. PROGRAMMING THE GYRO SETTINGS: PID (Proportional Integral Differential) correction The stabilising effect of the gyro sensors is based fundamentally on three parameters: P factor: defines proportional correction P = proportional: if the intended value is not the same as the actual value, then the difference is fed proportionally into the corrective signal; in simple terms, the input value (e) is multiplied by a fixed value: u(t) = Kp*e(t). Kp is termed the amplification value.
PAGE 13
Note: the standard P and D values should cause the gyros to correct the model’s attitude quickly when it is upset by an outside influence, without causing oscillation, but in practice the optimum values for a particular model can only be found by flight-testing. If the model displays little or no automatic stabilisation with the default settings, the value should be raised; on the other hand, if the model oscillates (wave-like movements in flight), the value should be reduced.
PAGE 14
4.2.2. Programming, transmitter without proportional controls • Move the cursor to the appropriate line, in this case “Ail” for aileron. • Press the SET button to activate the Channel field, select the appropriate value (1 - 10 of OFF), then press the SET button to save it. • First select a low value (see P factor section for starting points) and carry out a test-flight.

5. FIRMWARE UPDATE - GRAUPNER 33575 / 33576 / 33577 HOTT RECEIVERS Firmware updates are loaded into the receiver via the Channel 5 output, using a PC running Windows XP, Vista or 7. You will also need the separately available USB interface, Order No. 7168.6 and the adapter lead, Order No. 7168.6A or 7168.S (33575: additional adapter lead, Order No. 33565.1). The programs and files required for this can be found in the Download area for the corresponding products at www.graupner.de.
PAGE 16
When the file has loaded, click on Start … … connect the receiver, and switch itAon. B The progress bar shows the transfer proceeding normally. The receiver LED is off during this period, then flashes as soon as the file transfer is complete. Your PC may allow you to carry out a firmware update without a switch and receiver battery. In this case connect the components as shown below: USB lead Interface lead, Order No. 7168.S Interface adapter, Order No. 7168.6 Adapter lead Order No.
