I have the Venom Fail safe and..
Love it now... Check out thier web page, there was a recall on them, the older (small new model ones, if that makes sense) pre-May ones did not have the added note that if you were using it on a Traxxas (not positive it was just a T Maxx) that you had to save the side of the connector down (the one that goes in to the Rx on the truck from the Fail Safe). If this was not done fisrt you messed it up, just drop the old one in the mail and they will send you a new one. They did it for me, completely a perfect company to deal with!
