I am trying to install a forward looking video camera in my Bearhawk cowling to help with taxiing, its pretty blind over the cowling. I purchased a backup camera that installs in a 9/16" hole. I ...

This is on my Experimental. I have no idea what brand of PIDG Alcor used. The ones I purchased look identical. The A/P said these connectors are used on all new planes.

There is a local A/P that insists that special connectors are needed for CHT/EGT probes to prevent dissimilar metal problems affecting the readings. My Alcor probes have PIDG ring terminals and I purc ...

I am using dual lightspeed ignitions on my project. Lightspeed's instructions specify using 18ga shielded wire, the shield used as the ground return and wiring directly from the battery to a 7.5 amp p ...

I am installing dual lightspeed ignitions in my Bearhawk. 5100H1LC LEDs are speced as panel mounts to indicate when one of the ignitions is not powered. The LEDs are powered off a pin on the ignition ...

Not directly aircraft related but a tool that I use extensively in construction of my Bearhawk for shaping metal parts. The motor is now spooling up very slowly and when a load is placed on it, slows ...

Right now I am receiving the E-mail digests. It has been interrupted in the past for up to a couple weeks.

This discussion got me thinking that besides a transponder antenna I needed another antenna for ADS-B in/out. Turns out my thinking was correct for the Garmin equipment I am installing. The GNX 375 is ...

While shopping for a transponder antenna for a Garmin 45R, some are listed as open circuit and some as dc grounded. Is there any difference in the way they are mounted or perform? Also reading the AE ...

I will be installing a 6AH auxillary battery due to dual Lightspeed ignitions and to keep the EFIS alive during starting. I assume that both batteries should be grounded at the same location on the fi ...

Glad to hear that this relay checks out. I will order one to use as an aux battery contactor, will see 10-12 amp max.

The GMU 11 takes power directly from the bus through a 2 amp breaker. Maybe you were thinking of the GMU 22 which is powered through the GSU 25.

I plan on using Figure Z12 as the architecture for wiring my Bearhawk. In the process of converting the diagram to physical location for equipment and wire runs I noticed that the only wire that doesn ...
