QuickConnect Voltage
Recovery System for DSM2 Air receivers
Performance modelers have
known for some time that care must be taken to assure adequate
power supplies for their airborne system. It’s true for all
radio systems, but it’s doubly important when using
high-performance servos, flying harder maneuvers, and trying to
save weight with inadequate batteries and/or regulators.
Spektrum systems are
designed with an operating threshold of 3.5 volts, and lower
voltages cause the system to shut down. When adequate power is
regained (usually the drop is momentary), earlier Spektrum
systems re-boot and rescan for two previous channels before
control is restored – a process usually requiring two to five
seconds.
The new QuickConnect
feature, however, eliminates the scanning delay and restores
control almost instantly. We have been integrating this upgrade
into receivers in a running change. Here’s how to identify if
your receiver has QuickConnect:
With the system
operating normally, simply switch the airborne power off, then
on. If your system shows virtually no delay in regaining
control, your receiver includes the QuickConnect feature.
Flashing LEDs indicate low
voltage alert
QuickConnect allows most
flyers to fly through common low-voltage situations caused by
insufficient battery "headroom" – in many cases, without knowing
a problem ever occurred. As a result, Spektrum engineers decided
to program the system so that the receiver LEDs would flash,
should the QuickConnect feature be triggered in flight. This can
also be demonstrated on the bench, by toggling the airborne
power.
If your receiver is missing
one or both of these features, first off, it's important to
recognize that the vast majority of flyers using "normal" servos
with "normal" properly charged batteries will be unaffected by
low-voltage issues.
However, if you're using
numerous high-performance servos and wish to have your receiver
system modified, simply return it to Horizon for free upgrading.
Please return your receiver and all remotes, as all components
must have the upgraded software for the new features to
function. The best fix, however, remains assuring adequate power
supply to the airborne system with sufficient voltage headroom.
Your flying success is of
paramount importance to Spektrum as the leaders in spread
spectrum technology, we're constantly moving the bar upward.
