Center panel

Nice. What is the fourth (far right) push pull know in center?

Thanks! It's the second throttle. Unfortunately, the Rajay isn't producing much MP. You can see it only gave me an additional 2" @10k when I should be able to get up to 27"MP per the ops limits. Yet one more thing to have fixed. The joys of owning an airplane!

Your engine instruments are obviously the Mitchell modular, I was wondering: since they are not TSO was it hard to get approval? The original gauges were of a fairly poor quality, are no longer in manufacture and repairability is questional. I already have an external 2 1/4" oil temp but going this way ties up precious panel space. I myself think that the Mitchell modulars are the best solution aned am seriously considering installing them before another gauge fails.

Good question. I'll need to dig into the logbooks to see if it's in there. I was unaware of the instrument make and model.
