What are you guys using for a safety plug (switch) on your ships?

There's one available based on those Power Pole connectors.

I saw one on an rcuniverse (I think) that was made from a deans connector.

I was thinking about an automobile blade fuse, though I am not sure if it would hold up to the repeated connect/disconnect.

Anybody got a better scheme?

Thanks,
Chris

Hi Chris,

Below is the male part of the homemade Safety Plug. If a few grams are important to you, then you can also modify the commercial version, shown in the link I posted, by eliminating the two Deans connectors and just hard wire the unit into the RED positive wire going from the ESC to the battery.

Larry in SFO uses standard BULLET connectors for his safety plug. These have the two female parts glued into the plane about 1" apart with a small wire between the two male parts. These male parts are then both inserted (plugged) into their female sections and the circuit is complete. One male is "unplugged" to safely break the circuit. This is a very sano system, CAUTION: PLEASE DO NOT USE THE INEXPENSIVE "SPRING" TYPE UNITS THAT WE USE IN THE MOTOR TO ESC CONNECTION! .... THESE ARE NOT MEANT TO BE PULLED APART ALL THE TIME ...... THEY WILL FAIL IF USED IN THIS MANNER! ..... And, per Mr. Murphy, they won't just fail during level flight. ;-)

There are very good units available where the males are STIFF & SOLID and the females have a small slit in them with some sort of capture ring around them to keep the tight fit. You can usually find these in the model CAR section of your LHS. They cost a little more, but they are made for many duty cycles. This is perfect for our 1,000 flights per year flying schedule in CLPA.

I am using the Maxx product with the power pole plug on my SV 11, wire takes up some room which I will address on my next one, It's safe and positive. Regards Noel.
