The E2452 Lost RC Aircraft Beacon is a standalone lost RC aircraft beacon module which produces a loud beeping sound after a programmed time delay has elapsed or when triggered from a spare receiver channel. The programmed time delay varies between 1 to 72 times 20 minutes after being powered. This allows aircraft to be flown for regular flights before being reset unless the aircraft does not return in time such as due to a crash. Alternatively, the beeper can be enabled using a spare receiver channel prior to the time delay elapsing. Unlike other lost aircraft beepers, the E2452 module does not depend on a possibly non-functional receiver to power the beeper after a crash. The E2452 module instead uses a self-contained battery to sound a beeper for 1 second on and 10 seconds off to prolong battery life for over 24 hours while a search is in progress. A battery monitor beeps between one and five times to indicate battery strength. The modular form also minimizes the chance for damage after a crash. The beeper is very loud thus increasing the chances of recovering an aircraft in dense bush. The module can be attached and transferred to any aircraft.
