I don't have a comment on which instruments to purchase. I only want to agree with Roy on circuit breakers over fuses. Also I feel that you should not use small value breakers (or fuses) less than 4A or you will pay a price in lost volts.

I prefer 5A+ combo breaker/switches (i.e. Tyco W31) over plain breakers. Tyco's are bulky as compared to Klixon but the Tyco eliminates a separate switch and a additional failure point. I don't agree with using a plain breaker as a switch.

One other thing I like separate on/off switches for those avionics that don't have their own internal power off capability (I have two such devices - ClearNav and FLARM Core) to be able to reset a device or if you need to save dwindling power at the end of a long flight.

Best of luck.

John,

My problem is that I have identified 16 breakers and fuses. Some have to be fuses per Schleicher (about 4), so that leaves 12 breakers. The Tyco is over twice the area of the Klixon, by about 0.5 sq in. That means I have to come up with another 6 sq in of panel area, or 1 1/2 instruments. That just ain't happening.
