Welcome
This is the home site of the radio controlled lost model alarm. It is dedicated to provide an inexpensive but effective solution
to the danger of losing downed radio controlled models due to rough terrain and other obstructions.

Update
August 2, 2022 - In line with the times, due to technology advancements in alternative recovery options for remote models, our products have declined in demand and as a result we are stopping their active offering.
We will be leaving the web-site in place for a while as a reference. Thank you for your patronage!

Lost Model Alarm developed two modern but simple solutions to help recover
landed out of sight radio
controlled models. They are designed
to work with both modern and legacy radio controlled systems.
The alarms are installed in the radio controlled models in advance. When the alarms are triggered they emit a loud beeping sound that serves as a homing beacon and
guides the pilot to the landed model.
The difference between the two alarm devices is the triggering logic. The
actively triggered
lost model alarm device LMA-A is triggered by an explicit command either from the transmitter or the receiver's fail-safe.
The passively triggered lost model alarm device LMA-P is triggered after a period of inactivity
on behalf of the pilot or the receiver's fail-safe. Thus both alarms complement each other and can
accommodate any radio controlled set-up. Both devices will sound the alarm if no
servo signal is present from the receiver.
