In my experience, the gyro will only be helpfull when lack of grip is a concern, being on carpet at moderate speed or RCP at very high speed. The best way to see the gyro action is to drive on wooden floor or tiles. There you will see the rear wheels loose grip and the car instantly correct its trajectory to return in line. I was amazed when I saw this for the first time, a quick correction jump, just like a slotcar returning to its course after the guide has reached its rotation limit in a curve, if you see what I mean.

In normal race with the gyro, what I feel when cornering at high speed is some massive understeering but as soon as I release the throttle the car will turn frankly into the curve, or even oversteer if the front tires are soft enough. I don't feel any sort of correction on the throttle, only understeering like if the car was saying, "OK slow down now so we can turn". Remember that when the gyro enters in action it means that your car was already out of the line, so the same situation without the gyro would equal to spinning out (or countersteer if you are fast enough). This gives a very confident driving but I don't think it would be something the beginner would apprehend easily. The beginner would either go straight to the barrier due to the understeer or to the inside barrier because he was suddenly to slow. The amount of correction of the gyro has to be controlled with the throttle while it affects the steering, very strange indeed
I think the gyro will only control the steering, I may be wrong, but I never felt any loss of response with the throttle, either when entering or getting out of a curve or doing donuts.
If the gyro was transposed to the Mini-Z it may probably require a separated racing class.

There are both steering & throttle adjustments available for the dNaNo Gyro by way of the I.C.S. USB Adapter...

Interesting. I don't have the adaptor so my settings are stock. If it does control the throttle it would be for a very short time or by a very small amount. Powersliding is still possible.
On the other hand, the action on the steering is obvious.

BTW don't know if any have seen this video, this is the correction given to the steering depending of the overall orientation of the car at 1/4 the real time. At real time it is almost too fast to notice.

According to the documentation of the Gyro it assists with counter steer and reduces throttle to increase traction. However I have not noticed any real reduction in throttle but i have noticed the counter steer. I think that the track surface and the stock setting of the gyro are factors in this.

As soon as the track is set up at the Va Beach store we will be able to get more reliable conditions on a known track under and a controlled environment. I think that will give more conclusive data and show real results.

The steering and throttle gain can all be adjusted via the ICS cable. If it doesn't reduce the throttle enough for your liking, you can get the cable an adjust it.

Testing the gyro on the HTUSA track will definitely provide more concrete results. Everyone who has a gyro seems to have tested it on a different surface. lol

On the dNaNo ASF Manager the Steering and Throttle Gains for the Gyro are shown as a numeric value ranging from 1 to 255. The defualt setting is shown as 128...so the default setting is right in the middle of the adjustment range...
