Default Odd question - RC hovercraft

I have a 6 channel radio and receiver. The machine uses one fan/motor for lift, one for thrust and one servo for rudder.

I want to put the lift fan on one of the switch actuated channels on my radio (on, off, reverse settings)... however, I do not want the lift fan to be at full power at all times. Is there something that I can install before or after the ESC that would allow me to limit the RPMs of the lift fan?

I believe it is possible to set endpoints on the switch channels. Use them to limit power output.
I think you may be able to use a servo modulator..... but I don't know how.
If your Esc allows it, program it to limit output power.

Personally, assuming you are using an aircraft style controller, I would put the lift fan control on the throttle channel (the one without the spring), and use the other gimbal for steering/ forward thrust. This way, you can set the lift fan to a fixed throttle amount and leave it there. Steer can be put on either gimbal, but you must have a steady thumb to prevent the lift throttle position from changing.
