These Chinese Falcon VSI's are largely junk.
 The rotating shaft separated from its bearings.
 Could have been a jar from handling as it worked
 for awhile. It was handled by a few different people in
 the machine shop when the adapter was made to mount
 it in an existing hole on the instrument panel.
 These are much like clock mechanisms.

 I had to take it apart and reassemble it.
 Spent about 2 or 3 hours on the job.
 Steep learning curve.

 I don't recommend them. Not worth the $100 you
 save over the equivalent UMA brand  VSI made in the states.

 Paul,
 I like what you have done with the panel.
 GPS mounted to the side?  Have you decided to use the one that I gave you?

 Thanks but I am not done yet. Wait till you see what I am doing with the PCM :)
 All new better parts. PC board is 1.5 inches by 1.5 inches.

 I'll use that GPS (thanks) or the cheap one that I have. I am not sure where to mount it
 if at all.

 I am waiting for XWing to be available on the droid tablet.
 Horrors of  Horrors I'll buy an Ipad if necessary :) That will
 be mounted in front of the stick.

 The fold down UHF weather TV and camera display will be mounted up in the
 front of the canopy. At 12,000 feet one should be able to receive UHF TV channels
 100 miles out for real time nation wide weather and in flight entertainment :)

 The camera will be mounted just below the tail wheel spring.

 BTW what have you decided to with the Reno engine?

What is the best response time (precision/accuracy) of a GPS?
Fast enough for a digital VSI?  Probably not, huh!

They are usually a one second update rate but the big problems is
accuracy. You need a lot of sats to get a half way decent altitude
reading.

I would like an air data instrument using those very easy to read  OLED
displays that gave you true airspeed, altitude, rate of climb
(VSI) and transponder encoder. in one 2.25 unit.

RMI is out of biz and the RMI LCD sucked anyway. I think it can be done using 2
free scale pressure sensors and a computer of course. Makes sure all three
numbers are displayed all the time. No modes other than setting
the baro pressure. Modes have been a pain in the ass ever since
Word Perfect back in DOS days. Modes are one of the things that makes
Tracy computer so hard to use.

Would save a ton of money over discrete mech instruments hence would be worth
a ton of money and be far more rugged than fragile mechanical
instruments.

IMHO  a huge market for something like this.

Start working on it now for the coming world economy explosion.
The world economy will explode November 6, 2012 at 10 PM EST :)
Gold will go down!!!! The dollar and the market will go up!!!!
