Does anyone have an opinion of this instrument?

MGL Avionics AV-1 Attitude/Heading indicator fron Aircraft Spruce

quoting from AS "It's solid state and does not rely on the traditional mechanical gyro"

MGL make really good products. On this, no caging is needed, from their manual:
"Extended range of operationBank operates over a full 360 degree range allowing unlimited use of the horizon for aerobatics, provided that maximumpublished bank, pitch and yaw rates are not exceeded. Maximum rates under normal operation are approximately 165degrees per second, valid for all three axis simultaneously. Depending on conditions maximum rates may reach 180degrees per second. No caging of the electronic gyro system is required during excessive maneuvering or aerobatics,unlike systems based on mechanical gyros. Simply correct the horizon when you are finished or let the horizon right itselfwhich will happen during straight and level flight."

I just can't see the expense of a gyro in an acro plane....doesn't make sense to me.

I like the look of their products, however I tried to get some information from them last April and trying to communicate with the company was horrendous. I got the impression that they really didn't want to correspond with customers.

Another comment: The AV-1 you mention is only a 2.25" gauge, and the actual screen is smaller. Are you okay with it being that small?

"I just can't see the expense of a gyro in an acro plane.."

I agree if you are only doing local flying. If you are traveling now and then a gyro would be nice insurance. Going to the fly in at Bartelsville I was on top of a broken layer that was getting thinner and reported as clear ahead of me. I was going to have to stop for fuel before it was completely clear. If I had even a t&b I would have stayed up in the tail wind another hour. As it was I went down through a hole and bounced along 15kts slower. The "no old bold pilots" thing.

On the Vans Airforce site, they are regular contributors and seem to enjoy answering questions. They are from South Africa but the U.S. Distributor is in CA and he is a Christen Eagle owner. He has answered many questions for me.

They give very impressive feedback on vansairforce.com. The South African CEO regularly posts there and answers all questions. Here's one I blindly picked..http://www.vansairforce.com/community/showthread.php?t=83469
