Speed Sensitive Steering Module?
 

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.

For a few hi speed trucks. I adjusted my radio to do sort of like that.
I had it so the first part of steering was slower than the last. So if you move the wheel 10% it may only move the tires 5%. It made up for it later in the
Travel of the wheel though. Then again you not worried about percise movement in a tight turn situation. It made a big difference in how it drove
and handled. I can't think of what it is called right off top my head.

Hey Brian, what Leroy meant was probably the steering exponential rate. You can use a non-linear steering response curve, gives you less sensitivity around neutral. I use this myself sometimes, to cure the exact problem you described. Works surprisingly good.
Another thing I do sometimes, is to have 2 differnt sets of parameters (EPA's and steering speed) that you can change with the flick of a switch. (I don't know the proper term here, dual rate maybe?) Also pretty handy. You can push the swith when you enter the straight, and get super mellow steering, and when you come to the technical section, you switch back to the sensitive setting.

Hope you see what I mean

That is what I was talking about dafni. It works well. After you get used to it. it is hard to drive it without.

Yes, that also sounds like it would work, and I do believe it is called exponential steering. However, wouldn't the transmitter/receiver have to have this feature built-in? My Spektrum doesn't have that. :007:

My Tx/Rx does have a dual rate feature where you set your main settering EPA to whatever value and then there is a momentary switch (about where Ch3 of the Traxxas TQ3 would be), that you can use to quickly adjust the steering throw to a percentage of the set EPA. However, it would be tedious and clumsy to continually adjust it during a race for long straights to tight turns back-and-forth. I was looking for something that would do this feature automatically based on RPM.

Oh well. I guess I either live with the way my current Tx/Rx is set up or get a new Tx/Rx set. Poo.

Aha! I think I might have found something. Last item on the page.

I don't know if this thing does the trick. Sounds interesting, though.

I find it very strange that the Spektrum doesen't have steering expo.

Well, I skimmed through the manual last night and even went through the settings on the Tx and didn't see anything like that. Page 32 of the DX3 manual explains "dual rate" steering, but it's just the percentage adjustment I was talking about earlier.

My 3PK can do that I think, it judges it by however much throttle you give it.

On a larger note, my dads real car does it too. (VW Touran)

I don't know how you would adjust that device. But it seems to be what you want or close to it.

Yeah, I can't see where the RPM sensor would plug in. Unless it uses some kind of gyro mechanism??
