Try running the oil pressure's power input wire directly to the battery, just as a test. There might be a voltage drop in the electrical bus when you turn on loads.

Guy - I agree that there are many ADS-B In solutions. My ADS-B interest right now seeing if I can comply with the -Out requirements for under $2K as a target. A single box that combines the GPS and AD ...

Pat - I would very much like to spend some time in your neck of the woods. I think I mentioned I'm originally from Woodstock, IL. Sometimes I get to Poplar Grove for their annual fly-in. So we might m ...

I've been flying my Model I since 1994. A few upgrades along the way - traded the original pair of 6-gallon aluminum wingtanks for 13-gallon fiberglass tanks, added intercom, comm radio, and transpond ...

I had problems with the 866-080 regulator shortly after I got my aircraft flying. I changed to the 264-870 regulator (the one with fins on it). It regulates very close to 14 volts at full-throttle, wi ...

Hi Marco,

You're right - making mixture changes for getting the correct EGTs is quite acceptable. I wrote what I did because over the years I've heard people suggest changing the mixture for a qui ...

I routinely fly my 532 with a coolant temp of 180 and sometimes see 200-210 on a warm-day climb-out. That is no problem assuming you have the proper mix of coolant. Running 50/50 mix will provide a bo ...

This is a very good idea. However, some of the models have offset thrust centerlines. Ground-looping seems to be hardest on the landing gear, so tracking should be checked.

Some airframe damage wi ...

Hi Jared,

My 532 on a hot day might get to 170 while taxiing. I have a 140-degree thermostat, no airscoop, and a small, plastic-bottle reservoir. I get about 12 oz of expansion coolant into the re ...

Hi Guy,

The symptom you described is very much like the problem I was having when my prop was pitched to coarsely. My guess is that when you put on that extra 1/2 degree, the required prop torque ...

Hi Pat,

I got all kinds of different static RPM when my prop was pitched too coarse and the engine was too heavily loaded. In fact, it would run at 5600 for a bit and then drop to 4200 and sound l ...

Hi Pat,

Jared and I talked the other day offline. I mentioned my 532 static RPM was about 5800. But what I was shooting for was a Vx climb of 6600 RPM. When I finally got that, my static speed was ...

Jared, I've been flying with the same fuel pump, the original Minuki, for 20 years, but it sat around for two years before I ever flew it, so it's 22 years old. I carry a spare with me, though, and I ...

After I replaced the crankshaft in my 532, I had to repitch the prop. I was getting about 5200 RPM during static runups, when before the crankshaft exchange I was getting 6200. It turns out I needed t ...

The dent in my flaperon, repaired with regular automotive Bondo, have survived many years. I applied the Bondo to the bare aluminum. (The dents were caused by improper wing folding.)

The breather line is really a vent line, and should be run to a fitting located near the top of either wing tank.

What you have going on is essentially a big, growing "bubble" in the top ...

The Luscombe's updraft carb is located much farther below the wing tanks than the the Kitfox's side-draft carbs. So the Luscombe's head pressure at the carb is going to be a lot higher, and so will th ...

Mike,

All header tanks are installed with the same intention: insure fuel flow in 1) a dive, or 2) with one tank empty and the other tank unported due to a slip or skid.

Once upon a time, in th ...
