SECTION 2. Components and connecting

WARNING

Carefully monitor the battery voltage, especially during and after the first few flights, as a low battery
voltage can be fatal e.g. to maintaining a sufficient fuel flow.

Disconnect the battery from the ECU if it is not operated for several days.

2.5

GPS module

A GPS module can be connected to the corresponding outlet on the ECU. It does not need to be configured
via GSU. The GPS data is available in the corresponding menu (see Section 4.5.4) or can be transmitted by a
telemetry module.

2.6

Telemetry module

A telemetry module can be connected. It is placed between ECU and I/O board and usually comes with an
integrated battery. It needs to be configured via GSU in the corresponding menu (see Section 4.5.3).
