WarningRisk of injury by rotating propellers in case the motors start. Install the propellers only after the following programming.!

19 / 2816540_jh_V1

Commissioning version 16540.CAMTo start fling you need the following items:

� Transmitter HoTT (MX-12 / MZ-12 or higher)

� LiPo battery 3S, Graupner LiPo battery V-MAXX 50 C 3/1500 mAh, No. 9717.3.D35

� Video goggles or LCD monitor

ReceiverThe transmitter is already completely set for HoTT Hornet. To pro-gram some parameters, refer to the manual included with the receiver.

Battery installationFix the battery with the included velcro tape and the fleece pad into the battery case. Place the battery so that the tricopter’s center of gravity is in the middle of the frame.

Commissioning version 16540 or 16540.CThese versions can be completed with different assembly parts, pay attention to the use of the different parts in the manual.

We recommend the parts listed in the spare parts list because they are specifically made for the tricopter. Check the direction of rotation of the motors (see drawing on page 21).

It is possible to change the direction of rotation by reversing 2 motor connection cables.

Receiver’s bindingIf you wish to bind the receiver to a new model memory, this is the procedure:

� Switch the transmitter’s RF section off in the “Basic model settings” menu (see transmitter manual)

� Switch on the receiver and put it in binding mode, by press-ing and holding the binding button (green and red LED on the receiver are flashing)

� Initiate binding in the transmitter’s “Basic model settings” menu.

� If the red LED of the receiver goes out within about 10 sec-onds and the green LED is illuminated, the binding process has been completed successfully. Your transmitter/receiver combination is now ready for operation.

� If the red LED is still lit, the "binding“ failed. In this case, repeat the whole procedure.

20 / 28 16540_jh_V1

Necessary pre-settings on the transmitterIn the transmitter it must be selected a free model memory, the model type must be “surface model“ and the channel 1 direction must be set so that in “motor off“ position the power indicator must show -100%.

The flight mode must be set on channel 5. Then program a 2 way switch for channel 5 to control the flight mode:

Attitude mode: Channel 5 = -100% to +50%. The stick move-ment influences the HoTT Hornet reaction on Roll and Nick. It allows a maximal angle of about 50° at 100% of stick move-ment. Mode suggested for beginners. The stick movements acts directly proportionally to Roll and Nick.

Rate mode: Channel 5 = more than +50%. The stick movement influences the rate without angle limit. Aerobatic mode that allows rolls and loopings.

We suggest to set the fail-safe on channel 5 and channel 1 at -100% , so that in fail safe it is active the attitude mode.

Program always the motors stop switch on the transmitter. (See transmitter manual) This prevents accidental starting of motors, thus reducing the risk of injury.

Initialization of the gyro in the receiverOnce the HoTT Hornet has been switched on, the gyro immedi-ately becomes active but still needs to be initialized. To initialize the gyro, keep your HoTT Hornet still when you switch it on. The calibration process can only be performed when the receiver is absolutely still. After 3 seconds in still position you will hear beeps emitted by all motors.

These "wiggles" signal that initialization has been successful and that calibration is complete. Always wait until the calibration pro-cess has finished before starting to fly the model.

The motors will not start until the calibration is successfully completed.

Auto-flip function version 16540.CAMThe auto-flip function allows you to flip your copter in a very easy way. It is essential that you control in Attitude mode (function not allowed in Rate mode). The auto-flip function is controlled by a switch assigned to channel 6. (see manual S1019) Activate the switch and within 5 sec move the nick or roll stick to more than 50% of its course, then the copter makes autonomously a flip in the selected direction. After the flip it is possible to have some little position movements (<10°)

Do not forget to set the failsafe up!

Program the motor stop switch!

Installing the propellersWarning

Risk of injury by rotating propellers in case the motors start. Always unplug the XT-60 connector to the LiPo battery before working on the propellers.

Install the propellers as shown in the picture below. Pay atten-tion to install the proper propeller to each motor. The propeller rotation sense is written on the propeller (R/L)! The image rep-resents the copter seen from the top.

Pos. 1 - 1348.6x3 R C-Prop yellowPos. 2- 1348.6x3 L C-Prop yellowPos. 3 - 1348.6x3 L C-Prop red

First flightSwitch the transmitter on and plug the battery to prepare the HoTT Hornet to fly.

Unfold the arms completely and make sure they are in the cor-rect position.

Choose a free area for your first flight. Select first always the Atti-tude mode because so the copter is easier to control. Take firstly confidence with the flight attitude of the HoTT Hornet. Proceed carefully and responsibly.

The included Voltage module with SBEC offers you the possibility to set up to three different voltage alarms in steps of 0,1 V. Thus read the manual of the module and of your HoTT transmitter.
