Rob,

You are right. I am a Chinese currently working and flying in the US
(no, they are not together. Flying is just my hobby.) Both military
and civil Chinese airplane manufacturers(yes, there ARE airplane
manufacturers in China) avoid using China-made avionics if they have
the extra budget though I don't know if they all use China-made
gyros(they use China-made non-gyro instruments.)

I am 99% sure this guy's products are the same as those listed on
Aircraft Spruce. I don't know this guy, but I've talked to some
airplane homebuilders
in China (yes, there ARE airplane homebuilders in China though they
have to work mostly underground) who talked to this guy who obviously
boosted the sale of his products to overseas markets. By the way, this
guy's company is the subsidiary of the subsidiary of China's state-run
trade corp. of aviation products, so all this guy's products are
actually TSO's in China. But how could a gyro TSOed in China fail in
50-100 hours? mmm, don't ask me this question, I want to go back to
China and don't want to be killed by my extremist patriotist folks.

:Interesting to see your company has years of experience in aircraft
:instuments (according to your web site), and then turns to this group to
ask
:how long an electric gyro should last. Having some reliability problems,
erhaps?!?

I'm still not sure that's what he was asking. It might be - but I
think maybe he was trying to find out the size of the US market for
his product.

That's a possibility as well. However, the electric gyro shown on his
website looks very similar to the 'non-TCO' gyro listed by Aircraft Spruce.
It's made in China too. When I wanted to order it through the Aircraft
Spruce UK subsidiary they strongly adviced against it due to reliability
issues with the bearings. They claimed that the gyro's all stopped working
after 50-100 hours of operation.

I'm not absolutely sure that they are both the same product (China is a big
country..) but I found the correlation between his 'how long can it be used'
question and the bearing issue I was warned for too much of a coincidence
not to mention it..
