Tnt Snipes Posted April 3, 2011 Posted April 3, 2011 Can I make these work for my pitbuild ... or some how check if they are in working condition...??? i am really a layman in electronics n all so need guidance... [sIGPIC][/sIGPIC]
Maj. Raptor Posted April 3, 2011 Posted April 3, 2011 hmmm... don't think so... I chopped a lot of those instruments, its very difficult to understand how these electronics works. And if you try, you would need special powersupply. Most of them work with 400Hz AC. The best thing you could do is to open these Instruments and replace the syncro repeaters which moves the mechanics with a drive you know to control like a servo or a DC motor. :) regards
Gadroc Posted April 3, 2011 Posted April 3, 2011 You should be able to. Check out Mike's excellent books. He has instructions on how to make real instruments work. It will take work though.
Thermal Posted April 3, 2011 Posted April 3, 2011 The ASI and the vario will most likely run on air-pressure... no electrics/electronics. The turn and bank... that will have an internal gyro. There will not be a way to induce external input to drive that. You'll have to completely re-engineer the insides.

You'll have to completely re-engineer the insides. if there is a Pitot port you should be able to run this with compressed air/vacuum and a proportional valve... :smilewink: You can disconnect the needles with a soldering iron from the axes, and assemble a servo or stepper motor on this both instrumments. But its always painful to disassemble such a masterpiece of mechanical engineering. I first thought using original instruments the right way in a Simpit, is to leave them untouched. But even the Mil-Spec connector for clean connecting this many little pins on the back lay arround 100$ each. If I had a half F15 like Mike Powel (whose books a REALLY great) shure no way but just for fun, its better to use the re-engeneer way like Thermal says.
BHawthorne Posted April 3, 2011 Posted April 3, 2011 Yep, most real stuff is 400hz. You making an F-86 simpit? Two of those three gauges are common to my F-84F simpit.
Tnt Snipes Posted April 5, 2011 Author Posted April 5, 2011 thanks all of you guys... i think making these work is out of my league's job... no i am building A10C pit, thought it would give it somewhat better look... yeah i know these are taken out of F86's pit... i guess i should stick to helios or something... if anyone wants these lemme know...

BHawthorne Posted April 5, 2011 Posted April 5, 2011 (edited) I'm missing the vertical velocity indicator on my build and I already have an attitude indicator but it might be good to have a spare. The easiest way to go for gauges is to put an LCD behind the panel and emulate the gauges driven by LCD. It's a lot more cost effective than retrofitting aircores or stepper motors to old gauges. The only reason why I'm going with real gauges is I'm using a real fuselage and cockpit and want to keep the detail in the build as close to real as possible. Edited April 5, 2011 by BHawthorne
