From: "Rob Rowe" FYI - be aware that the pitot heater has a simple transistor circuit that only drives the green 'on' lamps (see attached diagram) when the heater is consuming power i.e. it monitors that the heater is actually working, not just being supplied with a voltage. So if the heater, resistor or associated wiring goes open circuit, or the transistor fails, the lamps will not light ... that could lead you to consider that the 10A breaker has died. The resistor (T4) & transistor (T5) can be found in the relay box on bulkhead 6 (at the back of rear instrument panel) if you want to check out the circuit. Hope this helps with your fault finding.

Now I want to add big ceiling fans and big lights. Bigass fans are really nice but way too expensive... so does anyone have any other fan suggestions? What about overhead lights? LED of course... any suggestions there?

Both have their own version of large building style, high velocity fans. I used 5 fans and placed one directly over the airplane where I would be working the most (engine and cockpit). As far as lights, the LED world is limitless. Look for High Bay style. Measure how high they will be mounted above the floor, know the beam angle and the charts will tell you their illumination area. Again place one directly over the engine/cockpit area and maybe have that on a separate switch so you won't have to light up the whole place especially if you have skylights.

Space them around the ceiling connected to one switch or 4 or 5 switches. You can get fans that look like the nose section of a different number of WW2 fighters. (P-40, P-51, F4D, etc.) They are a little more expensive than those at Homedepot. Lights. I have a 50x50 hangar. I have 3 rolls of 3 - 8' foot florescent lights. They OK but at times I wish I had 4 rolls instead of 3. Electrical outlets should be numerous! I have a 4 outlet box every 10' Make sure you have at least 2 220v outlets on either side of the hangar. I have only one and of course, it's in the wrong place. How you finish the floor makes you hangar special. Some like a real shiny polished finish. No good when wet with oil or water. One color, (mine is light blue) and as hard a two-part system as you can get. It needs to be stain proof. No speckles, it makes it harder to find that small washer you drop. Fill in all deep expansion joints with a flexible chauking. Every damn nut or bolt you drop heads right for the bottom of that cut. Paints you walls white. Helps with lighting.

I have adjusted my blades to almost a flat angle and still cannot hit 2350 RPM, my max has been 2250. I checked the small filter on the nosecase and it is clean, I am getting full movement on the actuator with no movement of the cable housing and my tach is accurate. Is my next step moving the arm on the governor?
