Speed Sensitive Steering Module?

[BrianG]

Is there such a thing as a speed sensitive steering module? My BL Jato turns very tight (about a 2 foot turning radius) which is good for tight turns, but when traveling at high speed, I have to be VERY careful with steering corrections. I'm looking for a module that uses an RPM sensor to reduce the steering range at high speed, but allows full throw at low speed. Ideally, at high speed, the full steering throw of the Tx wheel would equate to 2-5% of full servo steering (adjustable); while at low speed, the full steering throw would equate to 100%; with varying levels in between. I did a few searches and came up with nothing, but that could be because I'm not using the right search terms.
