help speed contoller gos flatout as soon as i switch on Ive had this prob before ???       but i cant for the life of me think what it was   

Martin (Admin):
Make? Model?

BobF:

Hi  Tubby_tomo,

As already asked, make and model will make it easier, but it could be as simple as the servo reverse switch on your transmitter is switched the wrong way.

Martin (Admin):
Also, as in my case, turn on the transmitter first.

Robert Davies:

A few years back I had the somewhat unfortunate experience of being on the wrong end of a failed speed controller.....

It involved a 1/10 scale car, and a motor that put the speed controller into thermal shutdown, and appeared to all intents and purposes to be deader than a very dead dead thing, when it cooled off however, it became apparent that it had failed in a most unfortunate manner.... FULL ON!!

Oh.. the fun we had....
