I think it'll be hard to get this to work, but it might be doable.

As you know, optical slaves are triggered by a flash, but RC relies on pre-flashes from the camera to control the flash, and if you are using TTL mode, you get even more pre-flashes from both the camera and the flash as the camera tries to gauge the level of power needed to light the subject.

I suppose you are already in manual flash mode. If not, that might be the main problem so switch to manual.

Then I would try to minimize the risk of pre-flashes from the camera setting off the optical flash. Turning down the power of the control light, or maybe also placing a bit of cardboard to block the line of sight between camera flash and the slave's sensor is worth trying.

If that fails, I think the only alternative is using a cable to fire the FL-300R.
