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.

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.

or “Hold” for a model helicopter, if a fail-safe event should occur. These settings ensure that the model is less likely to fly out of control if interference should occur, thereby helping to avoid property damage or even 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.

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.

PROGRAMMING THE GENERAL RECEIVER SETTINGS: The receiver can be programmed using a suitable HoTT transmitter or the SMART-BOX (Order No. 33700). 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. The method of accessing this menu is described in the operating instructions supplied with your transmitter or the Smart-Box.

uncontrollable. Channel 5 (Ch5): channel output 5 can be used to control a servo, as a telemetry socket or for voltage monitoring. If you activate voltage monitoring, the receiver can measure a voltage of up to max.25.5V DC via this input (instead of a servo or telemetry sensor) using the circuit described in section 3.1. The monitored voltage is then displayed on the screen instead of the receiver voltage.

‘Rudder elevator’ mixer can be set up at the transmitter instead of ‘Free mixer 3’ at the receiver; the mixer should be set up asymmetrically, e.g. +30%, -30%. This option frees up one mixer at the receiver. Delta with aileron differential (1 aileron) In this example aileron differential is set to 40%. Alternatively you may prefer to carry out the programming using the transmitter menu.

Aileron servos: you should enter the value 2 in this line if your model has two aileron servos; in this case the gyro for channel (servo) 2 also acts on servo 5. If the ailerons are also used as flaperons or speed brakes, gyro suppression is based on the sum of both channels. Please read the installation notes on page 5 of these instructions. The first step is to define the three gyro axes and the orientation of the receiver.

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 12
D = differential: in this case the corrective output value is affected by the rate of change of the input value, i.e. the faster the model tilts around the axis, the more pronounced the corrective response of the gyro. If the model changes attitude very gently, then the D factor causes hardly any corrective action. It also makes absolutely no difference how far the model has already changed attitude; the crucial value is only the speed or rate of the movement.

Procedure, using the ailerons as an example: • 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 channel, and save the setting with pressing the SET button again • move the corresponding proportional control to alter the factor (adjustment range 0 - 10; 0 means no gyro correction for that axis). • You can also adopt this factor directly by pressing the left button < or the right button >.
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.
