Optional Digital Tachometer (not included)
An optional Digital Tachometer
is available that can be directly
connected to the ignition and
display the RPM of the engine.
The Futaba ® DSC Charge
Adapter (FUTM4243) can be
mounted in the fuselage and
allows easy external plug-in of
the Digital Tachometer.
Many of the DLE Ignition modules have an additional lead to plug
into the Digital Tachometer. If your ignition module does not have
this additional lead, the Digital Tachometer can still be used. Simply
use the Y-harness (included with the Digital Tachometer) to connect to
the pick-up lead from the engine. Be sure to secure all connections
and to secure the Digital Tachometer or leads on the aircraft used.
