We want to know whether pilots like 2" or 2 1/4" ALT, ASI, VSI. They
are very important for us to develope miniature mechanical aircaft
instruments.

Thanks in advance.

I think there is a market for 2 1/4" instruments to serve as a backup
to electronic flight displays. That said, I have purchased a couple
of gyro instruments that were manufactured in China and they were
completely unacceptable. They did not function very well out of the
box and both failed in less than 200 hours of use. Warranty support
was practically non-existent. I replaced them with US made units that
have worked flawlessly.

I realize that there is a fine line between keeping the cost down and
building a high-quality, reliable instrument. I think that you will
find the US market appreciates quality and reliability and will pay
extra for it. I am in the market for a 2 1/4", 3-pointer, sensitive
altimeter with baro set window right now.
