try mike patterson's setting from ROAR Nats in portland. i used it in stock and was happy with it. of course his settings were for 19T. PM Me if you need the settings. or you can also go to www.kopropo.com and download it from there.

prodrive-
You may want to check you linkage and make sure that it is not binding. Try taking off the servo horn and see if you still have the same problem. If you don't, then it is the linkage. If you do, you may want to get your radio checked and recalibrated.

The only thing that you could try is the deadband adjustment on the servo. That may help. The PC interface is the same, but will require a Y-harness. One end goes to the PC interface, one to the servo and one to a receiver pack for power.

Yeah I did see that setting, but it was for asphalt correct? Most of the time foam on carpet produces far more traction, as well as mad forward bite. I guess I'm asking if i could start at 6 vs. starting at 10 and coming back down?

this may be in the wrong thread, But

I have a ko servero a 2123. I have heard that this is a fet servo, but mine does not have a fet lead. It is an older servo. Did they change those servos at some point? I purchased it used, so could the previous owner have cut it? I can open it up and look inside, where would the wire for the fet part be on the circuit board?

TIA

The blue 7.2V lead comes from under the PC board. If the wire is not there and the servo works, then it is not the PDS-2123. They may have just changed the upper case with the PDS-2123's upper case. The servo will not work unless the 7.2V lead is attached.

robk... starting at 6 will give you more punch. the reason the settings are started at 10 or 11 and held there for two stages is to minimize wheel spin. but (ive never raced on carpet so correct me if im wrong) on carpet, since there is so much traction, you'll be able to use that setting more effectively. check your runtime too since 6 is such a low setting.

I have just updated the vfs help center on the KO site. I have posted the setting used from 03 ROAR carpet nationals, 04 snowbirds (carpet) and Hara's 04 KO Grand Prix setting.

I was looking at the 04 Snowbirds 19T & 27T setting and it goes down to 1. Is that safe?

It is safe, but will require a motor rebuild after every run. Just trying to squeeze as much out of the motor and esc as possible.

I would recommend using the hyper booster along with the super shotki diode. In reference to using two or more, would only help with adjustable timing motors. I don't see a difference with two on a stock motor, 19T maybe. But there are some that do use two in stock and swear by it. Just their opinion.
