SECTION 4. Using the Ground Support Unit (GSU)

4

Using the Ground Support Unit (GSU)

The GSU is a small terminal with an LCD with two lines and 16 characters each and four buttons (up

, down

, escape

and enter

).

Figure 3: An AeroDesignWorks GSU.

WARNING

Do not permanently install the GSU in the aircraft model, as the LCD might have a negative impact on
the RC’s range!

Regardless, the GSU can be used to change ECU parameters while the engine is running.

• The menu can be navigated up (

) and down (

), sub menus can be entered (

) and left (

).

• Values can be adjusted up (

), down (

), saved (

) or discarded (

). Changes to values are written to the

EEPROM automatically upon saving them.

• When the engine is in

standby

mode, the start sequence can be initiated by simultaneously pressing up

(

) and escape (

). This might be needed if one H

ORNET

-III is used to simultaneously control more than

one engine.

• The expert menu can be unlocked by simultaneously pressing and holding up (

) and down (

), see

Section 4.5.6.

4.1

Power on messages

After starting the ECU, some messages will be displayed on the GSU. The startup procedure will also produce
some messages.

1. ECU and firmware version, e.g

HORNET-III CS E

V3.0 2021-10-22

In this example, a H

ORNET

-III-ClubSport is used and its expert mode is unlocked, signified by the last

character

E

on the first line.

2. The engine that was connected last, e.g.

005 AEROD.WORKS

B140F

The three digit number is the model ID of the engine.
