Another Great Addition!!!
The NAV heads from OC came today.
Well worth the money with only a few descrepancies.
1. The edge of one of the faceplates was not painted allowing light bleed through. Easily fixed.
2. Holes not big enough for Dusz fasteners. Also easily remedied.
3. LED backlighting leads for the NAV engraving left too long and LED's stuck out in the area where the module sits on the Dusz rail. CAREFULLY fixed by removing the LED's, retrimming the leads and re-installing on the circuit card. This should not have left the building without being corrected.
Someone else may not have been able to repair it, or even want to attempt it if they could.
4. Translation for installation needs work.
Now, for all of the above, they are still a bargain. You couldn't even buy one NAV head from the competitors for the price I paid for both. They function the same, they look the same, and they fit the same using standard Boeing rack width spacing.
Why pay more?
The encoders are fast and precise, though lacking a bit of stiffness like on the Collins heads. Just something to get used to. The Collins heads also use a mechanical switch which is something to consider.
I'm very happy with my purchase. I hope they eventually produce a USB ADF head and a USB transponder. I'll be the first in line.
