Northstar on/off switch tip

       Remove this ad - become a site supporter!
When I built my first Northstar many years ago I was trying to find a good way to install the on/off switch.
I installed a thin tube in the center of the nose before I filled it with birdshot and epoxy. I then mounted the switch so that a thin rod would pass through the tube to actuate the switch. On the outside end of the rod was a old style metal thumb tack. It is almost invisible to the naked eye. Pull out for on.
As I was flying off water, the theory was if I nosed it into the water the force of impact would shut down the radio before water got to it. Well it worked perfectly. I had an episode of pilot error and hit the lake at 3/4 throttle. The only thing left was my engine and radio. Thanks to the radio shutting down I never had any future problems with it.

Re: Northstar on/off switch tip

My luck vibes from the engine would have shut it down in flight!

As it is I have something similar on the Seamaster 40, with a push/pull tube exiting aft of the wing saddle. It's set up so that water would have to go uphill to make it into the radio compartment.

This is the rig on my Northstar. Sorry for the poor exposure. Still trying out the new photo program. The switch and charge jack are to the lower right.

p.s. Would love to see some pics of your plane.
