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.

May 1, 2012 - We are very excited to announce that following the initial
launch of the lost model alarm devices last year, building on their growing popularity
and success we are releasing their new improved models!
The most significant new feature for both LMA-A and LMA-P alarms is their built-in compatibility with higher voltages, resulting in a broad operating range between 3V and 9V. You can now use the lost model alarms without any additional modifications for any battery pack that your receiver and servos can handle!
We are also now offering the passively triggered LMA-P lost model alarm in a selection of inactivity timeout values: 1, 3, 5, 10 minutes.
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.
