Mike, welcome to the forum. I'd say that's possible. After all the airplane radios have racheting throttle sticks. One would just need to get in touch with Futaba and ask them for the parts to do the conversion. I've converted radios the other way. From rachet to spring loaded neutral, but not the other way around. Most radios have the ability to be converted. The rachet mechanism is usually inside the radio, from the factory. You just need the metal clip, to engage the racheting part of the stick.
