I picked up an MKS 292 gyro from Xheli.com and tested it out.
It
mounts vertically so the label on it needs to be facing sideways. The
nice thing about it is that the gain dial on the gyro when using the
gain channel from your TX acts as a limit adjustment. That's a big
advantage over other gyros in it's price range available in the US. It
also has a reverse setting (They use a dial turned all the way one way
or the other to set reverse). The only quirky thing I found was
the gyro MUST be started up in HH mode. If you start it up switched in
Rate mode, it will NOT initialize so always look at the light on the
Gyro like normal. I always recommend doing a quick gyro test before
each flight. I lift my heli and put my finger on the tail slider I then
jerk the heli Nose-left and make sure the tail slider compensates by
moving left (pinching my finger). I found the manual for this gyro online. I found it hard to understand and rewrote it here:
MKS 292 Manual rewritten It
held pretty decent on my EXI 450. I have a digital tail servo on
it. It held pretty well in punch outs, flips and backwards flight.
Much better than my Esky 704A or Telebee gyros I have. This
helicopter is going back into my Scale 500D fuse, so I mounted the gyro
on the side where I can see it and adjust it. Using a side mount gyro
is a nice feature for scale helicopters that make it harder to get
to the inside of a top or bottom mounted gyro.
