I have been a HITEC user for many years and have never given much thought to the S, J, And Z type connectors. I recently acquired another plane with FUTABA servos already installed. Could somebody tell me what will mix and match between the different manufacturers of radio equipment? I carefully filed the small lip off of the FUTABA male plug and it fits and works with my HITEC receiver. I think my HITEC equipment has the "S" type, but I'm not really sure. Any advice would be appreciated.

My Feedback: (1)

The currant plugs used by the four majors are:

Hitec - S plug
JR - JR plug
Futaba - J plug
Airtronics - Z plug

The plug polarity of all these plugs are now identical and if plugged in backwards will not damage anything, just won,t work. JR, Airtronics and Hitec are also mechanically compatable and the Futaba is also if the spline is removed.

The older style Airtronics black with the three splines are not mechanically compatable and have reversed positive and negative pins.

The much older Futaba G with exposed pins is also not compatable.

One last note beware of the charge jack on JR Transmitters as the jack has a center pin negative plug. So using a JR wall charger on another brand or using another brands wall charger on a JR tx will cause damage.
