<<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> << Lancair Builders' Mail List >> <<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> Dave, there is a 2 1/4 inch Jet brand gyro that was made for military installations and more recently for commercial jets. The surplus ones have to be overhauled to be worth using and one will set you back well over a grand. New ones are about 6,000 bucks. Dewey at Pacific Coast Avionics may be able to help you find an overhauled one, and if you don't have luck there, drop me a personal email. I have another source that may have some in stock. They are all 28 volts so you have to have a converter. They also should be mounted low in the panel with an 8degree upslope so that the horizon bar will be in the right pace. I thought you bought Tony D's airplane and, if I recall, it already has the Jet gyro. Tony couldn't figure out why the horizon bar wouldn't center and we talked about the 8 degree upslope. Even though this gadget is expensive it will run about 15 or 20 minutes after power loss, so it can get you right side up to the ground in your glider (if you are all electric ignition) when the electricity quits. I bought some inexpensive instruments for altimeter etc from Dewey as well. They were new and seem fine. The altimeter is a single needle 20,000 foot instrument, so won't be particularly valuable in normal flight most of the time on cross countries. In the event of emergencies, I figure I'll be getting down below Flight Level 200 ASAP anyway and that's where this instrument will be useful. These are good backups to the SFS EFIS. Regards, John Barrett I am looking for some used 2-1/4 inch instruments as >follows a) 1- Electric Artificial Horizon (14 VDC) b) 1- Altimeter Any advice on where to located yellow tagged 2-1/4" >instruments at reasonable prices would be appreciated.
