Ok, just a wee problem.
Whe I was driving my robot around something really awfull happened again, again and again.
I drove my robot round for a minute and then suddenly it jolts forward and goes out of control randomly driving around, do I jumped on it and yanked the link out.l
This happened 5 times.
We (me and bodge job) lookedd at the wiring and everything was ok.
Don't know what the problemo is.

Could be radio interference

If you are using the BEC from the sabertooth it may be dropping out and you need to put in an external BEC. You should also check the switch setting to see you have the failsafes set correctly.

Also what receiver are you using for it?

I'm using the planet T5 radio system with a R6m RX
I'll try the failsafe on the electronize

I'm sorry to say I think you will find that something has shaken loose on the Sabertooth board,
If it is under guarantee call the supplier and get it looked at.
I assume the robot worked OK and then for no very good reason started doing this,
I had a problem like this when I used the Sabertooth in the first Seraph
it turned out to be the Capacitors on the top had worked loose (I now glue them down)
Give the capacitors a little tug and see if anything moves.

The battery I am using is a 12v 3300mAh NiMh

It was fully charged
I got it early this years so it may be under warranty i'll try the thing with the capacitors

battery fully charged look at the speedo

The electronize is mounted directly above it, so it may be interfearence but i doubt it.
I had a look at my speedo and it looked fine i'll do some tests with it later today.

It may be something to do with the circuit bored, armourdillo had the same problem as lazer, now I think about it, it was just that components wasn't soldered in properly
