through the two ports marked “B” at the top of the servo block.
LED Indicators
The LED indicators simply indicate that power is present for the unit and the
receiver. They are not indicators of power being within an acceptable range.
Optional Failsafe-switch
The PowerSystem Sport Plus supports the addition of a failsafe switch (optional
package). The PowerSystem Sport Plus supports 2-cell lithium packs, ion or poly.
When using the failsafe-switch, the switch lead is plugged into the input marked
“Sw” near the top left of the servo connections as shown on the reference drawing.
Smart-Fly can supply two types of failsafe switches. First is the standard slide
switch that most people are familiar with. This is a small slide switch with out a
charge jack. The second failsafe-switch is the Pin&Flag switch, where a pin, with a
flag on in, is inserted into the switch to turn the system off. To fly, the pin is pulled
out of the switch. The advantage of the Pin&Flag switch is that the system cannot
accidentally be turned off, as can be the case with a slide switch. The failsafe switch
lead can be extended using a standard Futaba extension.
The PowerSystem Sport Plus also supports charging the batteries through the two
charge connections denoted by the “C” next to the battery input ports, one on the top
of each servo output rail as shown on the reference drawing. The optional failsafe-
switch package includes two charge leads and two Ernst charge jack mounts. The
charge leads have a Futaba male on one end and a JR male on the other end. You
may use these by plugging either end into the PowerSystem Sport Plus and the other
end into the charge jack holder.
The charge jacks on the PowerSystem Sport Plus can also be used to connect to a
battery meter. One thing to keep in mind when using a battery meter and the
failsafe-switch is that the jacks are not switched off when the unit is off so the
battery meter will continue to draw power when the unit is turned off.
Ignition Cutoff
A separate manual is supplied to instruct you on the use of the Igntion Cutoff. The
Cutoff channel is determined by using the six-inch jumper supplied. The Futaba
male end should be plugged into the port marked “Ig” The other side of the jumper
can be inserted in any servo output channel or it can be connected directly to the
receiver, for example, on channel nine of a nine-channel receiver.
