I read an old article in which these plugs were used as a "shorting" plug to turn the radio on and off. Thus increasing the rundunacy of the radio system. Do these plugs have a "tight" fit to them? I don't want to worry about them vibrating out. (120cc gas plane. I asked here because I know electric flyers use these sometimes.) Thanks, alot!

Deans Ultras are known for their tight fit -- you'll even see complaints about it. In fact, the fit can be so tight that some users file grooves in the plastic housing to give their fingers something to grab on to.

The Deans plug is most likely the most popular plug used on electrics. Very tight fit, very easy to solder onto stuff.

Thanks guys. Sounds like what I need. Now to figure out a couple of "trap doors" for the side of the plane.
