I only have one plane with a toggle on it, the plane is a big gasser with a mag ignition and it's just used as a safety switch or kill switch for the ignition. It's just something for my pit man to reach if the plane for any reason gets away from me during starting and starts removing some of my favorite parts. As the starter I always have my TX next to me, I want the switch easy for him to reach and flip off.
Other then that I use the heavy duty JR switches for all of my planes, I have had those little switches that come with radios and flight packs go out on me, never one of the JRs.
