NCFM Black Jack Switch

With the male plug inserted, the plane is turned off allowing your battery to be charged and voltage checked. To fly simply unplug the red phone plug and the plane is 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.
