  • Quality built, small and efficient. Must have for flying!

    Being somewhat new to Quad racing I figured this was a must have for my 250. I needed something small, lightweight, and effective to pack inside that will let me know when my play time is up. With this voltage alarm from TargetHobby I am also able to help locate my missing quad in the event that I get too carried away and stick it in a tree or in the middle of a corn field……

  • A nice buzzer for any plane

  • Good value, good quality.

    The 3 in 1 unit does exactly as the overview xes robes and is of good quality for the low price.
    The low voltage alarm has a fairly accurate threshold per each of the 4 settings, though I didn’t dare take any of my LiPo packs to the lower settings, staying at 3.7v per cell. Using the 3 in 1 on a 450SE with both 2S and 3S, the alarm begins to sound intermittently at around……
