Hi all
Has anyone tried using a 1/8th in. jack as a arming plug? I was thinking about counter sinking the female on the bottom of the plane.
Thanks

Too little surface contact area there.
Connection will go over the top temperature wise big time.

Works just great on one of my gliders.  I'm driving 4 tiny servos and the RX.  Doubles as a charging port.  I have a four 1/3AA Nimh battery pack installed.

Probably pretty light for most other purposes.

It might work, but if folks are correct about the current capacity, the plug might weld itself to the jack.  It would then be hard to disassemble, because the nut on the jack wouldn't come off past the plug.  The good news is that the plug wouldn't fall out when you pull out of a wingover, as Motorman feared.

This is correct.  With a "switched" jack when the plug is removed the contacts are in bypass internally, connecting and turning on the circuit.  With the plug removed the circuit is through the jack instead, allowing for charging. 

This might be the thing for some OTS ignition engines with rechargeable batteries.  Plug in the charging cord disconnects the battery from the circuit.  This is the same as my use with my glider.

The bestest and cheapest is the Deans Ultra Plug (large 2-pin red ones).  A 16 ga. wire loop makes it easy to see and easy to pull out.
