I assume these are the same for the Keyence Zero v Ext.. -JB

Yup.

Adrian,

I checked the neutral setting of the ESC. You're right, it's set to 9p. I set it back to 4p. I'll test the change on weekend.

Aside from this setting, is there anything else that can affect punch? Is it possible to visually inspect the surface-mounted FETs for damage?

Thanks!

Keyence Customer service rocks. They hooked me up and quickly.

Ninja - If you had a FET problem you would have a massive lack of top speed. If you lack punch check your drive frequency. For stock it should be 2.5 (2500Hz) or less. If it is really high, over 5.0 you will certainly feel a lack of punch.

Adrian to the rescue!! Your on here more than me!!

is there any hints to reset the esc? i have changed radio gear,and i go to set it the way the manual says,and in set mode,evrything just goes to the highest value.it seems as though its not reciving any signals.

Hello, I'm witnesing what you said. Lack of top speed! How can I be sure that a fet is broken?

I live in Greece, where should I sent it in case the esc has problem?

Thank you

Nick

Moot - The values are all going up because the speedo thinks trigger neutral is the throttle high point. This happens if you make a error in setting it to the transmitter.

To set the speedo to your transmitter follow this procedure:

1. Make sure you radio is set to 100% end points for brake and throttle and no more. LRP used to recommend setting your radio to 140% before setting your speedo. Keyences do not like this.

2. Turn it on your transmitter and speedo.

3. Hit the center button to enter the "Set" mode.

4. Push the center button and hold it until your see "nutr"( approximately 6 seconds). If you saw "nutr" right away you pushed too far to the right and you are not in the right place. If you did it right you will see all the LED bars on the display count up then "nutr " appears.

5. Once you see "nutr" do not touch your transmitters trigger ands hit the right button on your speedo. You just set the neutral point.

6. The display will switch to "dr_hp". Pull full throttle on the trigger, hold it and while holding full throttle hit the right button on your speedo. You just set the throttle high point.


7. The display will switch to "br_hp". Push full brake hold it and while holding full brake hit the right button on your speedo. You just set the brake high point.

8. The display will switch to "Set" and you can now program your speedo by hitting the right button.

Just like on any other brand of speedo you have to move quickly. You have 5 seconds to hit the right button in every mode If you go too slow the speedo will move on to the next setting ands you will need to start over.

I'm having the same problem (lack of top speed). How can I check if the FETs are to blame?

I live in Greece, where should I sent it in case the esc has problem?

If you think you have a problem the only way to be sure is to send it back. In the US you can send it to us for repair. Out side the US I think you will have to send it back to Keyence.

There isn't a representative in Europe? (I think Schumacher sells Keyence).

Can I send it to you? After all I bought it from US (speedtechrc)

Thank you

Nick

Schu UK only repairs speedo imported and sold by them and their dealers. Schu USA has the same policy. We don't repair units sold by Ultimate hobbies or Ricky's R/C as they import their own.

You can send it to the US if you want to but it would be a lot cheaper and faster to send it to Japan. The address is on the back of the instruction manual. They are very fast with repairs.

will give it a go! thanks for the help

HELL YEAH Adrian, thanx ABUNCH -JB
