Necessary pre-settings on the transmitter

In 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 receiver

Once 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.CAM

The 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!
