Flight #22


Added 40 more pounds of water. This time to the baggage compartment. I’m walking the CG backwards a bit at a time from the 80.04 empty to the rear limit of 86.8. Takeoff for this flight was CG=84.3.

Due to a visual on heavy rain to the west, decided to takeoff and stay in the pattern for 30 minutes. After 30 minutes of doing 8 takeoffs and landings in the pattern, it appeared the rain wasn’t moving in or getting any worse so I picked up the flight plan and departed to the west. Wind was from the east and keeping the rain to the west from approaching. Experienced rain in the RV for the first time deliberately during this flight since I could dart into and out of the showers (this was light rain falling from clouds high above). No apparent leaks. Flew along the edge of a line of rain with clear to the east (Fredericksburg) and rain showers to the west (Madison/Greene). Darting to the North allowed me to get out over Rappahannock to the west and circle Mom’s house for a bit.

Upped the G’s to 2.83 G’s max during a few maneuvers.

Flight #9 – Oil Pressure Gauge – Offscale high

On March 12, 2016, I went to the airport with the intention of doing 3 takeoffs and landings to warm the oil for the engine’s first oil change. Taxi out and runup went fine. Oil pressure in the 50’s during idle and in the 70’s during fast taxi. The first takeoff and landing went fine with oil pressure in the 70’s and 80’s. But during taxi back for the 2nd takeoff, the oil pressure sensor went off scale high very rapidly. I considered shutting down in the runup block, but all other parameters seemed normal so I thought it would be safe to taxi back to the hangar for diagnosis.

During the taxi back to the hangar, the gauge continued to read off scale high. At the hangar, I shut down the engine, and didn’t think to check the gauge before powering off the avionics. I then reapplied power to the avionics with the engine off and noted the gauge had returned to zero.

The Kavlico oil pressure gauge, is a 3-wire device with red, black, and green wires. The red wire is +5V supply from the avionics, the black wire is ground, and the green wire is sensor output. I learned from reading that 0.5 volts out is likely 0 PSI, and 4.5 volts out is likely 150 PSI. Downloading the data showed that when it went off scale high it was reading 154 PSI. This might be an indication the output wire was getting shorted to the +5V.

I disconnected the wiring to the sensor on the firewall forward side and checked all connections for security and/or damage.

0.5 Engine Time, 1.0 Total Time (11.6/13.5 Cumulative)

Wrapping the wings in vinyl

Now 3/4 done with the wings and learning how to wrap better. I bought a rubber roller from the crafts store and that helps to push down and get the adhesive to stick with less chance of scraping the surface.

I tried using a spray polymer wax after finishing the right wing and that seemed to add a nice finish.

Aircraft Polishing Equipment

I’m just getting started, so don’t take this as recommended. This is just what I was able to pick up locally when I suddenly got the bug to try some polishing:

Griots 6″ random orbit polishing buffer & red foam pad. Since I’m cheap, I put microfiber cloths over the foam pad and used that to help keep the red foam pad from getting filled with polish and super dirty. I washed the first 24 or so cloths that I used in the washing machine. Bob on VAF says I should try TCP mixed with water in a 5 gallon bucket to soak prior to washing. I’m itching to try that, but haven’t found the TCP yet.


White diamond metal polish. I don’t know if I’m doing a bad thing here using this since it has a “sealant”.


Zwipes microfiber 16″x24″ cloths. These are pretty thin and not very plush, but what I was able to have on hand to start with. Bob on VAF told me the ones on perfect polish are “a MILLION” times better. I’m going to try picking some of those up.

Here is a quick before and after surface condition shot. This is about 3 minutes of work by hand, using the zwipe cloths and the white diamond polish. I apply a small amount of liquid polish to the metal and rub with the microfiber till the paste turns black. Then wipe off with two successive passes with clean microfiber cloths:


Not close to mirror finish and not all scratches gone, but pretty good for 3 minutes by hand. It also took off the sharpie which I couldn’t even do with MEK:

Aircraft Polishing

Well, I certainly don’t know what I am doing, but I decided to polish the plane for a bit prior to committing to paint. I started with the right wing top surface:


Since I don’t have the good stuff yet (Nuvite), I just did a quick pass with stuff available at autozone. I bought a 6″ random orbit buffer, some foam pads, and used microfiber cloths under the foam pads to apply the cleaning polish. My first goal was just to git rid of the surface oxidation and remove the discolored lines left from the removal of the blue plastic along each side of each rivet line.

Although this still looks like crap, it is 100% better than before where it was milky/blotchy with obvious marks on each side of the rivet lines:IMG_0588

Getting better:IMG_0594


You sure go through microfiber towels quickly. I took these home to wash and it took two cycles in the washing machine.



Today (1/3/16), I did the left wing, with help from Rachel and Zack:
