Sorry, but I don't think they will. Take a look at the face of a Novak XXtra receiver, the brands that are on the same side are the ones that will work together.

Namely: Futaba and HiTec will work together. Then all the other brands will work together. Airs, JR, KO, Multiplex...are all interchangeable.

It all has to do with what shift of the wave band the different companies are on, I believe. Futaba and Hitec are on negative shift, while everyone else is on positive shift. Al least thats how I think it breaks down.

Try the crystals and see, just to be sure, but I believe I'm correct.

My experience is such that Crystal need to purchase with
the same brand as the transmitter. I have tested with Sanwa (Airtronics) & Futaba.

Sanwa crystal in Sanwa TX and RX works,
Sanwa crystal in Sanwa TX and Futaba RX works.
Futaba crystal in Futaba TX and RX works
Futaba crystal in Futaba TX and Sanwa RX works

Sanwa crystal in Futaba TX doesn't work, likewise,
Futaba crystal in Sanwa TX doesn't work.
