No appreciable difference for our application - recommend purchase on price point
Lost Model Alarm
providing auditory cues. ○ Passive (dumb) and Active (user control) alarms ○ 85db ○ $8.00 ea. ○ 14mm diameter, 14mm tall ○ Operating Voltage: 3V - 9V ○ 20mA draw when sounding ○ Plugs directly into Rx
LED Strobe
providing visual cues.
○ Pre-soldered with easy mounting ○ 50mA operational draw ○ 3-6V operational voltage - servo current ○ Power Circuitry Included ○ Cost: ~$10 ○ Plugs directly into Rx or APM
~$25 worth of parts can be the difference between lost & found.
○ No faults observed - servo and throttle tested ■ Due to relative signal strength
○ Multiple 5 minute test at various ranges
No amount of testing will rule out possible failure due to interference
tests
○ Does not allow for use of “Return Home” function ○ Tactic is a “parkflyer” radio
testing with equipment (~$70)
○ Utilize Aero Design’s DX6i Tx ○ Includes a “satellite receiver” for long range transmission fidelity ○ DX6i has 3-position switches, allowing for “Return Home” function to work
Higher quality receiver is an easy way to mitigate signal loss risk at range
