Other incidence meters

[Keith Black]

I give it a mixed review. In general it works, but my experience is that the
laser doesn't always come to rest at the same location. In other words, if
you give the laser a nudge and cause it to swing back and forth it won't
always stop at the same spot. Sometimes it's higher, sometimes lower, and
other times it will come back to the same location.

Also, the balancing wheel is so sensitive that if you take it off of the
wing and put it back on the same wing often times it doesn't read the same.
This could be due to the inconsistent laser or could be that the balance
wheels moves slightly, I'm not sure. Certainly this makes it difficult to be
sure two wings are exactly the same when going back to the same wing may not
read the same.

The only way I'm able to use it is going back and forth multiple times and
seeing if it's still reading the same. Also, once set, swing the laser four
or five times and see which spot it lands on most often. This certainly
isn't very scientific.

What I always end up doing is just getting things as close as possible and
then flying it to dial in the exact required incidences.

I've seen threads on RCU where people set zero incidence on non-adjustable
stabs using this tool, I think that's a BIG mistake. Flat table with
measuring devices is the best approach.

It could be that I just have a defective one, but I've heard others that had
the same experience as I have had.
