1.3MM DC CO-AX POWER PLUG

I bought a micro minature camera system (2.4ghz.) about 10-15 years ago (still works)! I don't remember the brand name. I used very little, except for a local thief, in jail, thank God!!.
I recently plan to build a 6 electric motor R/C "helicopter" with a parallax's system. However, the camera was powered by a wall wart (power pak), thru a 1.3mm DC connector! Eurika! I found it! AE has it... Thanks AE!! KD5BIH
