RC Allen Gyros

Sometime back I got tired of fighting Aircraft Quality Instruments trying to
get a Gyro Horizon that worked, so I purchased a new RC Allen Horizon. This
was April of 2002.

Guess what--- the horizon failed in flight last week. The warrantee was one
year. Upon removal, I found a part rattling around inside the instrument. I
returned it to the factory with a note, that even though the warrantee had
expired, I would expect the instrument to last longer than 18 months. I
further explained that the horizon could be considered as a crucial
instrument that should be relied upon, and parts falling off inside is
unacceptable.

We'll see how they treat me. I'll report back what the factory says.

Maybe the gyro gods just don't want me to have a working horizon. G

In my opinion, RC Allen gear blows chunks. That is just how their stuff is.

Bought an new *electric* RC Allen in 2001 as a backup after the primary AI
died in IMC. Overhauled it in Mar of 2003. Warranty overhaul in Aug '03.
Again in Oct. Now working but sounds like its going to come apart any
second - very noisy gyro.

Working with local FSDO to figure out if there is any legal way to put one
of these in as a standby -

(fits in a 3 1/8" hole....)

RC Allen is junk.

You might want to watch the guy who is doing your installations.
I've seen experienced technicians, who had no idea how easy it is to damage
gyro bearings, do stupid things like set a new attitude indicator down on a
bench without padding.
When the gyro is not spinning, dropping one the width of a pencil onto a
hard surface will damage the bearings.

Actually, spinning does not protect the unit much. Installation in a
panel is what protects the beasts. Without the "damping" of the entire
airplane, the shocks of mishandling greatly increase the risk of bearing
damage. You can impart a 10g shock to a pencil with a flick of your
finger. To impart a 10g shock to the panel of an airplane usually takes
a crash.

Put a gyro instrument on an unpadded cart and roll it across the hangar
(hitting an expansion crack or 2) and you can bet the unit will fail
early. As you stated, even a small drop can damage it.

Good Luck,
Mike
