I have been lucky enough to be sent one of Rh1no's own design and built kill switches to perform some testing and feedback. The switch is similar in design to the setco relay switch but without the big chunky relay and weak circuit board and some neat added features.
The switch constantly monitors the input signal from the receiver and will maintain it's current switch position during periods of minor signal loss or interferance. It will automatically switch off the ignition power if it detects an invaild reciever signal for more than 0.75 seconds duration and will then stay off until the reciever power is cycled.
The switch itself is of great quallity, it is small and very light weight yet it looks very strong and vibration resistant. All solder joints are very well done and once again look strong and made to last.
Installation was a breeze. I used all the supplied leads and ferite ring. As this is a prototype I am unsure of what will be supplied with the switch if and when it goes into production. There are 3 connections on the switch one goes to the rx, another to the Ignition battery and the third to the ignition unit. I also added an external switch (between the ignition battery and the kill switch) with charging jack to the airframe this makes charging a very simple process but is not a necessity. The switch itself I mounted wrapped in foam (leaving the indicating LED visable) and velcroed to the inner part of my fuse.
Programing the switch is as easy as setting the travel to 100% each way, and setting the direction of the channel the switch works from. On mine I use the gear channel, forward on and back off.
With the installation complete it is now time to move onto the flight testing, which I will conduct this weekend. I'm sure it will a non event as Rh1no has had the other prototype in use on his own plane for quite a while now.
Here are some pics of the setup.
