edbond Posted November 25, 2006 Share Posted November 25, 2006 Hi, I am a little confused, I thought the Optidrive provided a failsafe for battery / radio reception, but I have been reading that I need an aftermarket failsafe !? If I need one, do I need a special kind, or do any work ? Thanks Ed Quote Link to comment Share on other sites More sharing options...

Curt Posted November 27, 2006 Share Posted November 27, 2006 If you have a return spring on your carb you don't really need a failsafe, although if your running with alot of other rc'ers you might want to get one incase someone is running the sam freguancy.
