I've ordered a carb temp gauge which will replace the clock when the panel is opened up to replace a defective taxi light switch. Hidden by the left yoke is an S-Tec 50 two axis autopilot with altitude hold. Since this picture was taken, the defective switch was replaced with one from my radio junkbox. This way the two most commonly used couplings can be selected with a quick flip of the switch. Romeo's old style instrument grouping makes it harder for the instructor to check my altitude.
Some people have a problem with the old style arrangement.
Others, including my IFR ground school instructor, do not. It didn't take long for me to get used to Romeo's layout, so the old arrangement doesn't bother me.
