Sushi Boy--

I just spoke to Adrian over at Schumacher (they are the distributor for Keyence here in the States).

He gave me the following recommendations for 1/12th mod:

Neutral width (%) 4
Min drive power (%) 0
Min braking power (%) 0
Neutral brake (%) 0
Compression retarder off
Drive Frequency (KHz) 3.5 (no less than 2, no greater than 5)
Braking Frequency (KHz) 4.0
Power limit (%) 100
Voltage of battery... 4.6 (this feature is just for feedback,
doesn't affect performance).

Neutral width is a personal preference. It determines when power is sent to the car from the neutral point of your throttle. Some people like it to come on with the slightest touch of the throttle (hence a lower #), or some like a little more "time" with the throttle before power is sent (hence a higher #).

By setting the min drive and braking power to 0%, you are making the control full linear.

The drive frequency is another personal preference and the 3.5 is just a starting point. Basically, if you want the car to feel punchier, reduce the drive frequency, and visa versa if you want it to be smoother. However, you want to try to stay within that 2 to 5 range.

Also, if you start reducing your drive frequency to gain more punch, be sure to check the motor comm and brushes. If they start to look burnt or heavily discolored, you may be getting too low on the frequency (providing that your gearing is correct).

Brake frequency is sort of like drive frequency. The higher the number, the smoother the braking will feel, and visa versa the lower the number. I would tend to stay on the higher side for this as you don't want the braking action to be "grabby" or abrupt.

I didn't ask him about 1/12 stock settings (because I don't run it), but you can contact him at ShumacherUSA (813) 889-9691 or PM him here on rctech (I think his username is AdrianM).

He was very nice and extremely helpful. So, I wouldn't hesitate to contact him with any and all questions.

Hope this helps,
DT
