mad rat problem please help

[billyboy9002]

hi

i have got a stock mad rat brushless 2.4ghz setup, which i just got off ebay.
when i took it out for the first run it was stuttering, moving about 3 inches at a time, when i lifted the car off the floor and pressed the trigger nothing at all happened even with a fully charged battery

any ideas what it could be?

cheers

Is is brand new or second hand? What batteries have you put into it? What charger do you have? How long was it on charge?

[billyboy9002]

it was second hand, the battery is a 3000 nimh and it was on charge for 1 hour on a fast charger

Have you tried recalibrating the speedo to the transmitter to see if that's the issue?

[billyboy9002]

peetbee- how do i do that?

[peetbee]

There's normally a setup button on the esc. If you tell us which speedo it's got then hopefully someone who knows it can talk you through it.

My guess is the batteries life is up. mimh's can appear to be charging even when they are stuffed.

The first thing I would do is get a new battery and make sure you have a peak detection charger. (One that cuts off when the battery is fully charged).

For some reason, I can't edit my last post.

Anyway, here's the setup manual for your ESC;
www.ftp.ansmann.de/Brushless_Set_Xirius.pdf
The link isn't working for me from here, but if you go to the Ansmann.de website, enter " manual " into the search box, then scroll down to your ESC,then the pdf setup manual is available for download under the brushless subcategory.

i will give that a try with the battery, my esc is not on the list i will try a google search to see if i can find it,
will see if it is the battery first though to try to eliminate one thing at a time otherwise i might get a bit confused with what i have done

Hi Billy,

I've just checked again, and the Xirius brushless ESC is definitely there.

If you can't find it, i'll download it and send it to you. Just PM your email address mate.

scroll down right to the bottom and click on:

manual for the Xirius brushless speed control

The esc has a little red button on the on/off switch which is used to setup the esc to your radio.

...go to basic setup section 1st mate.
