pilots either time their flights or listen for the motor performance to change. ESCs with factory preset "soft" cutouts are typically set to activate at 3v per series cell which often doesn't give enought time to react and land safely. Timing a flight is often inaccurate because of changing conditions and listening for performance change is a pain. Flying is much more enjoyable when you don't have to be concerned with timing or trying to listen for the motor to change pitch. The LVS 32 allows you to safely milk every bit of juice possible from a LiPo pack giving you maximum flying time on every flight regardless of changing conditions and flying styles. When power is connected the LVS 32's LED briefly flashes to verify it's operating and has gone into monitoring "standby" mode. On "A/V" unit styles, both a brief flash and audible tone are emitted. During flight the LVS 32 is on "active standby" drawing only a few micro-amps. In "active standby" it continually monitors voltage and what effect the system "load" is have on the pack's health. When the voltage weakens and drops to the preset threshold, the alert is activated which means under that "load" condition you have about 25% of your flying time left. If the "load" is reduced enough, the alert will subside until the threshold is reached again. When the alert remains "steady on"... there's nothing to think or worry about. There's more than adequate time for a safe full power-on landing. The LVS 32 pays for itself on every flight by maximizing flight time without the nuisance of flight timing and listening. All guesswork and battery pack worry is eliminated.

ERC makes several ELT instruments to choose from. Fixed or adjustable time type and the "missing pulse" type. Respectively they are named the SOS I, II & III. The fixed time instruments are as simple as turning it on and pushing an arming button. Easier yet, for the missing pulse type, when you're looking for your "pride and joy", just turn off the TX and it automatically begins its piercing high pitched alert.

 

SOS Alert I FT (Fixed Time Alert)

Enables a modeler to quickly locate a downed aircraft in rough terrain via a piercing audible alert signal. It's rugged compact SMT design consists of an IC timer chip, an on/off switch, a remote mounted arming PB Switch, an external 86db piezo sounder and 9v battery cap. Since Rx battery packs sometimes disconnect on impact, an independent 9v battery is an advantageous feature.

Operation is simple. After the pre-flight check, turn the SOS power switch on and you will hear an audible signal indicating Active Standby status. Push the auto timing button when you're ready to taxi out to begin an auto timeout cycle of approximately 18 minutes at which time a continuous piercing signal can be heard from at least 100 ft. away. To deactivate, either push the PB switch again or turn off the power switch. Easy 5 minute installation. PCB is enclosed in a mini high impact ABS case designed to protect against impact shock, severe vibration, moisture and fuel.

 

SOS Alert II AT (Adjustable Time Alert 12-22 minutes)

Functions exactly as the SOS Alert I. The only difference is the timer. Instead of timing out for a fixed amount of time, it's user programmable over a range of 12 to 22 minutes. It's programmed via a PCB mounted micro-pot that easily adjusts with only a medium small slothead screwdriver. It's powered by 9 volt Alkaline battery and protected from the elements within a mini high impact ABS module. Its rugged SMT design lends to its high resistance to impact shock, severe vibration, moisture and fuel.

 

SOS Alert III SL (Lost Signal Pulse, constant 86db)

The SOS III works on a principle known as MPD (missing pulse detection). It continuously monitors the train of signal pulses sent out by the TX (transmitter). If the signal is lost or interrupted longer than 5 seconds, it automatically sounds a loud constant alert from an internal piezo element. The alert ceases when the signal is regained or the RX power switch is turned off. The SOS III and its 86db constant piezo are well protected from the elements. It's designed to be reliable through a variety of abusive conditions such as shock from a strong impact, severe vibration, moisture and fuel. The SOS III plugs into a free or "Y's" into a used RX (receiver) channel slot. No current is used until the unit activates. Other than the power lead, there are no other external wires or parts.

NOTE: An optional aux input can be ordered and added to the SOS III. The aux input will accommodate any number of off the shelf sounders. ERC makes a special self-powered warbling 120db ear splitting sounder called the Mighty Mite Alarm designed to plug into this input. Or, you may opt for an ERC special Ultra-Bright LED lead to either plug into the input or even "Y" into the external Piezo sounder providing both audio and visual warning for after sunset mishaps.

 

SOS Alert IV SL (Lost Signal Pulse, warbling 108db)

Same as the SOS III, but emits a 108db warbling alert.

endure extreme shock, severe vibration, moisture and fuels. Easy hook and loop installation. The FLT consists of a power lead with a mini inline on/off switch, a micro PB (push button) arming switch and a very high intensity, #10 bin (highest LED rating) Ultra-Bright LED. The cutting edge LEDs are daylight visible in the sunlight for over 150 yards. You may order the FLT Alert with either one LED, referred to as a "Remote" or two LEDs called "Twin-Lites". An optional 86db 14mm or 110db 32mm piezo sounder is also available for that additional audio reminder/warning. less...

 

Consquently, automatic onboard flight timing is not just a good idea but should be considered a necessity. It's far more reliable than guesswork and a snap to use. Just turn the power on and push a button. The rest is automatic. The FLT Alert has an adjustable 12 to 22 minute timing cycle. Programming is easily done via a micro-pot that's accessed through a small adjustment hole in the case top. A jeweler's slothead screwdriver is all that is necessary. The FLT Alert also doubles as a "Lost Plane Finder" since it automatically activates when the "time out" cycle completes. less...
