It is my PRIMARY AI. I also have a vacuum backup. The battery is overpriced compared to a battery but not compared to the value of knowing which way is up. My understanding is that the TBO is high because the RPM is low. I made the electric my primary because IMO it has a lower chance of failure than a vacuum system. I think one thing to consider is a) the context in which you would be using a battery backed gyro and b) how different it feels to rely on this device under normal conditions. For (a) chances are you already have a lot of problems and things are already feeling pretty weird. for (b), I have an RC Allen in my cessna two holes away from the VAC AI. It's responsiveness is enough slower that it really feels different to fly behind it. In every other respect it looks just like a vac AI. I would be curious how different it would be to fly behind the tru-trak. I am betting that the 4300 feels like a normal AI. If it doesn't, I will have to tear apart my panel.
