Make one transmitter run four receiver/controllers?
I need to get four of electronic exhaust cutouts ( https://www.ebay.com/itm/162664518133 ) to run on the same transmitter button... how can I do this?
I have two so far that I wired to one receiver and was surprised that it run bothe motors, do you know if that will hold up long running two motors on one receiver? Later on I will get two more if my experiment works and pretty sure that one receiver probably would not run four motors, so any ideas how I should get two motors for now and four motors later to run in sequence? Can I change the frequency in the receivers to match one transmitter and or can The transmitters fequencies be readjusted so I can have more than one transmitter on the same frequency, if that is not asking too much? Thank You...

The motors appear to be just two wire units, presumably with internal limit switches.
If that is the case then you could use one receiver plus a couple of suitably heavy duty change-over relays to run all the motors.
The receiver output would connect to the relay coils, using a diode in series with each so one relay operates on one polarity and the other relay operates on the other polarity.
Connect the motors between the commons of the two relay contacts.
Connect both normally closed to ground (battery -) and moth normally opens to +12V via a suitable fuse.
When one relay is energised, it connects that side of the motors to power, with the other side still grounded viea the unpowered relay. The other polarity from the RX pulls in the other relay instead and the motors run the opposite way.
This diagram shows the idea of the motor connections:

It is possible that one receiver could run 4 cutouts, but a safer alternative would be to wire the receiver to the coil of a relay, and then switch as many cutouts as you want from the relay.
