With the male plug inserted, the R/C system installed is turned off, allowing your receiver battery to be charged and voltage checked externally. To fly, simply remove the red plug and the electronica are turned on… put the plug in your pocket and launch!
This is an UNWIRED switch / charging jack combo. You must be comfortable with soldering tiny things into tinier places and have the ability to shrink-wrap. If not, you may want to seek the help of someone who can.
We have opted to sell just the raw parts, for a minimal price, since many pilots like to “roll their own”. (Pre-wired versions are also available online for around $30, from various sources). NCFM BlackJacks are sold UNWIRED ONLY.
