Hi,

  I want to share some pics of my real 737 TRIM AIR VALVE  ordered  from BONEYARD2U (Lee) few days ago, so Trevor, it fits PERFECT with my Engravity overhead without need any modification ! The only thing that i changed was the backlight lamps with 3mm yellow leds to match with all FI overhead gauges and made it to power ON with all FI backlight.  ;)

Great stuff Carlos..  Mine hasn't arrived yet..  Darn dog sled's  :o   I am so glad, it fits and the pics are awesome.   :rock:

Thanks Trevor ! Very strange that your's didn't arrived yet. Mine arrived yesterday...i think that we had order on the same day if i am not wrong.
Another great  information is that the needle works with some little input voltage like 0,02 volts to move from full left to near middle and something around 0,04 volts to move it to full right side. I think that will be not difficult to simulate the needle movement when OPEN or CLOSE switch are set. At this moment I fixed mine to the middle.

Fantastic..  I can't wait to get mine now even more..  You are right.. inputting little voltage like that would be easy to simulate.  heck a simple capacitor charging and discharging would create a real nice waving motion on the needle..

Great information, Thanks Carlos.

PS.  Canada Customs is a real pain in the ASS to deal with, I may not see mine for weeks.

Looks great!

I did the same thing with the yaw damper flags on my flight control surface position indicator. It runs on a 3VDC wall wart. A 1.5VDC battery didn't move the flags, and 5VDC banged them to the stops.

Yaw dampers on, flags disappear.
