Default Charging Polarity: Futaba Vs. Airtronics

Hey Fellas, I was wondering if anyone knows if the polarities are oposite for charging a Futaba then charging an Airtronics TX. I run Futaba on my planes and Heli's, but I have an Airtronics M8 on the way for my Cars. Thanks!!

Hitec, Airtronics and Futaba use a center pin positive on there Tx charge jacks.

JR is the only odd man out with a centerpin negative on their Tx charge jack.

Never use a JR wall charger on any other brand Tx or vice versa. The JR wall charger for the flight pack is however the same as all the four majors.

I don't know the dimensions on the Airtronics, but; the inner connector on the Hitec is 2.1mm in diameter while the Futaba inner diameter is 2.5mm. Polarity is okay, just mechanical fit is different.
