Hall ASI accurate?

[GrantR]

Are the Hall ASIs accurate?

[jcarleto]

Yes and no.

They are highly accurate if precisely pointed and somewhat less than accurate otherwise. You want to try one? (I took the one off of the GyRonimo I had while learning and it is just sitting in a drawer now)

FYI - The man who invented that instrument lives just a few miles from me. I have been to his hangar and seem some of the many projects he has developed. Very home taught tinkerer kind of guy but very smart too. I thought it was cool.

I've got one mounted on the jury strut of my Challenger. Seems to be dead-on with my ASI at all speeds from stall to cruise. My max wot speed exceeds the indicator by about 8 mph. It's the 0-80 mph gauge.

It's mounted straight ahead level at 50mph.

Yup.
If it's mounted in clear air, and it's relatively easy to see out in front of you.

I used one on my plane and got one on my bee! pretty accurate against a gps in zero winds! :yo:

Grant,
I have one one the KB 4, I think it is accurate. I checked it against my truck speedometer it was the same, I don't have gps or another guage to compare it to. It only goes to 80, but thats fast enough for your 503
