The Airtronics Z type connector is the same as HiTec and Jr. You should have no problem using either of those with Airtronics Z. Futaba has a keyway on the connector that has to be trimmed off to use it with Airtronics Z.
the Z connect allows almost unlimited use with other equipment.
be careful to keep the positive and negative in the correct order though. a lot of connectors will go on to z either way so it's easy to cross positive with negative.
