Mike,

There is no good reason not to use it IMO! Many of us make our own. I currently do not use one since I went 2.4ghz. But I may put one back in my next plane as I just don't feel right not having it even though I feel the chance for a failure with my radio setup is 0 or close to zero. I have a friend that hopefully is asking one of his other EE techs at work about the possibility of an esc having an opening failure from an off position. With my setup, you would have to bind to the receiver to turn on the esc, so I have a hard time seeing how it could fail. Not saying it can't though. I just haven't been shown how yet. My friend is also an EE btw. So hopefully they can figure out if it can fail from an off position, with no signal from the radio, and with 0 power as the caps on the esc would bleed down pretty quick.

I used the Deans Ultras for years with good success. Well, unless you count when I lost them. I always made plenty so that I could lose a few at the field. hehe Friends of mine use the Astro Flight Zero Loss as it's a little easier to get in and out. Others use the wire with a 4mm bullet. I don't like how any of them look really, but you can't see that in the air.
