Testflight 2&3

Yesterday I removed the cowling and checked all wires and connections. Everything looked good and there was no new oil stains from the first flight. I now cleaned off the stains that came from the first engine start. In the evening I performed two more flights.

The first flight consumed less than 1/2 quarts of oil. Here is "the inside view" from the first flight.


I now have 3.2 hours airborne. There are two big squaks:

1. My radio transmissions are almost unreadable, I tried adjusting mic gain but now suspect a physical wiring problem most likely a short to ground at the headset connectors.

2. I lost manifold pressure reading! As I know what the fuel flow should be for 2500rpm and 75-80%, I continued the last flight as planned without MP reading.

All in all am am very happy but the above problems must be fixed before flight 4. The engine uses less than 0.5 quarts per hour and temps are very good. Unfortunately I forgot to take or copy the logs from the SD card so I do not have any data from flight 2&3 yet.

No, yes, maybe, no, yes!

Woke up to a low cloud base and rain! Checked the forecast several times before lunch, it looked like there could be a 3 hour break. Of to the airport and after a hopeless hour I refueled but put the RV back into the hangar, the chances of flying was very slim.

Installed my now overhauled 35R and it started looking better again. As there was so little traffic I decided that I did not need a dependable 4000 feet cloud base, an initial cloud base of 3000 and a worst case scenario for landing at 1500 would be enough.

Of I went. For the first hour I could fly at between 4000 and 2500 feet AGL and for the last 30 min at 2000-2500.

The only real squawk was that my com transmit became worse as the flight continued. I could hear everyone else fine but they got lots of static from me. After 30 minutes of bad coms I decided that 1:30 airborne would have to be enough for the first flight.

I will try to make a better movie later on, all onboard GoPros was out of power after about an hour so no onboard media from the landing.


Vans will be notified tomorrow :D

Closing in

Today I prepared for the new manifold pressure sensor.

I disconnected everything and laid out tools and parts for a quick installation of the new sensor as soon as it arrives. I took some pictures of the removed sensor, more on this later.

Then performed several task that are not really necessary for the first flight but nice to have, I mounted two RAM balls for a camera and phone/tablet on the left side of the panel. I put one GoPro mount on each wing and cleaned up the wiring some.

When I got home I looked at the picture of the removed sensor and discovered that it was a P4055-5025-3 sensor. That is for fuel pressure, not manifold pressure! So the question is now, did I mix up these sensors and is my manifold pressure sensor sitting where it measures oil or fuel pressure?

Frustrating

So I have had all needed permit since almost a week now. There is only one "show stopper" preventing the first flight:

- my manifold pressure sensor does not work. After trouble shooting for several hours including completely rewiring the connection, I have given up on it and have ordered a new sensor.

My faulty transponder is still travelling to the retailer but that will/would not prevent me from making a first flight in uncontrolled airspace. Pretty sure I will not fly this weekend, I think Tuesday the 16th is the first realistic possibility for the first flight :/
 

7/4/19

One of three still needed permits received

I just got a copy of my "Certificate of registration" and information on that the original is in the mail. this also means that my two other remaining permits are on its way.


To be allowed to fly I also need the flight test permit for the aircraft and the radio license. I do not think that I will get up in the air this weekend even if I get the permits on time, to many other activities planned. But sometime next week if the weather cooperates. :)

Expecting permits any day now

I should receive all needed permits any time now. While waiting I am performing smaller improvements. Today I started exchanging some of the EGT/CHT sensor wiring. I had mixed the HI/LO wires and when starting to solve the problem I just decided that the cables are to short.

My transponder is on recalibration/repair/exchange so currently I am limited to days/time when the airport is closed and thre is uncontrolled airspace up to 4500 feet. Next slots that also fits my calendar are early on Saturday or next Tuesday evening...

I have one new/remaining show stopper, my manifold pressure sensor is not working.

Where is my camera

Mixed feelings about today. One big negative was that I took no pictures from the visit to the airport. The biggest plus was that my kids behaved fantastic, filling up the RV at the pumps, calibrating the EFIS-Fuel pump senders with a 4 and 6 year old around worked great!

After refueling I tested cycling the prop. It worked already on the second try. Did one more to verify and then taxied to the hangar and shut down. This was my first longer taxi, the visibility is great even for a short guy like me. Stearing the RV-14 during slow taxi is very easy.

The list

New:
- Used a to long screw while attaching the upper leg fairing resulting in that I unbonded the glassed in nut.
- Do something about the EGT/CHT and more wiring, I had no reading during the taxi today


Done:
- Finish the paper work (Now very likely)
- Paint the last three letters of the registration marks (the vinyl came loose)
- Wire the elevator trim correctly
- make the flap switch move the flaps in the right direction
- Rewire the magnetometer
- Re-calibrate the magnetometer
- Validate all G3X green/yellow/red band settings
- Attach the wing walk spacers with the proper hardware
- Proof of Insurance, not sure what if anything was actually wrong but my insurance agent will send a new copy to the authorities.
- Corrected ELT information. I had mistakenly filled out the 15 digit HEX "serial number" of my ELT and not the 15 digit HEX ID number. After spending more than three hours searching for the documentation it was an easy fix. Turns out that I have posh looking folder for important RV documentation that I had forgot about ;)
- Prop cycle
- Verify/redo fuel tank sender calibration

Remaining:
- Solve the right stick trim down button not working
- Connect the landing light
- Get the transponder working (Sent it via DHL today)
- Fix the right upper gear fairing, glassed it in tonight, sanding planned for tomorrow
- Do something about the EGT/CHT and more wiring
- Another engine run with proper EGT/CHT reading and a short full power run.

Other things to be done soon but not necessary before first flight:
- Install aileron trim
- Install autopilot servos
- Install tablet holder
All that can be done at home...

Inspection passed!

So this week the inspection was done, I have a very short list of to-dos before being formally ready for flight.

I need to mount the needed engraved signs (one has to be from stainless steel), I received earlier this week. I need to put the "Experimental" sign in place. I need to securely fasten the fire extinguisher and that's about it.

Then on my personal show-stopper is:

- Connect the landing light
- Get the transponder working
- Wire the elevator trim correctly
- make the flap switch move the flaps in the right direction
- Rewire the magnetometer (done today)
- Re-calibrate the magnetometer (done today)
- Verify/redo fuel tank sender calibration
- Validate all G3X green/yellow/red band settings
- Attach the wing walk spacers with the proper hardware (I got the needed AN507C832R8 today)
- Another engine run with proper EGT/CHT reading, prop cycle and a short full power run.

Other things to be done soon but not necessary before first flight:

First engine start

Another long day. Started at home, trying to finish the paperwork for the inspection, realized that it would not be possible to be anywhere close to 100% ready. Decided to go to the hangar to get the aircraft ready for inspection.

I have some tasks to do like actually mounting the fire extinguisher, place some markings like "experimental". This will be done and shown via photos to the inspector. The physical inspection went well and we decided to finish up the paperwork part later in the week.

Then it was time to try and start the engine. The first attempts were not successful, we checked and could verify that the engine received fuel... put the battery on the charger and started to trouble shoot. I had a suspicion already while trying to start the engine but I decided to charge the battery first and verify.

I remembered thinking a lot about the mag switches, I fully understand the concept of preventing them to function by grounding them, somehow I anyhow managed to install them up side down! Very embarrassing.

After charging the AC battery it was time for the next try, my GoPro had very little power left, Lars main task was to be ready with the fire extinguisher also filmed with his mobile, this was great as very little of the successful start was recorded by the GoPro.

I did not get any EGT reading and soon also lost CHT so the run was kept very short, ended with a slow lead to check rpm rise, result almost exactly 100 rpm.

Drove home with a great smile on my face during the entire 1:30 trip (some traffic on a Sunday evening)

W&B

Almost 12 hours in the hangar today. Lots of small tasks to be done before bringing out the scales. 

First was solving the non-running fuel pump. It turned out that I had not connected the ground, very embarrassing! Fixed that, and performed the fuel flow test as an easy way to get out the fuel from the tanks. Result, it takes just short of 23 seconds to deliver one liter. That is over 156 l/h or more than 41 gallons per hour!

Most things moved along great, one nutplate in the wheel fairings decided to give up and capture the screw. had to drill it out and put in another nutplate. 

As I had done the measurements and tested for leveling the AC, the actual test was done in a very short time frame. 
Almost ready to get up on the scales.

Recording values

So 261.2 kg on the left wheel, 263,4 on the right and 25,2 on the tail wheel.


Lst task of the day, had to enlarge the opening some more.

6/7/19

Lots done w&b tomorrow

Lots done today, took the afternoon off from work.

 Arms are measured, close to Vans example so I should be good. Will make another check during the test tomorrow.
 I envy those capable of bleeding breakes without creating a mess, my 2$ pump gave up just as I was finished. Not tested yet but I think I managed to keep air away. Filled from the bottom.
 Removing te cover from the canopy, within seconds there was dust on it.

6/6/19

Preparation for w&b

Working hard to be ready for putting it on the scales on Saturday.







6/3/19

GMU11

Not fitted yet but I think this will work.

Good and bad

Another day at the airport.

Got my registration marks painted under the wing, this would have been so much easier to do before the wings was mounted to the airplane!

Getting the washers in place when attaching the elevator controls was difficult, should have done this before mounting the vertical stabilizer. Then the molex connector on the trim wires broke, after reading about others problems with these connectors it was probably for the best that I had to hard wire them instead.



I finished off with testing my nav and strobe lights. All nav lights worked, the strobe worked in the tail and on the left wingtip but not on the right wingtip, to be investigated.

5/23/19

Tail attachment 1

Oldest had no school today so we had a great day at the airport. I managed to lend a lorry from work, solving the problem of transporting the stabilizer that would not fit into a car.








After a long day I was ready to go home, my son then asked if we could fly! There is only one answer to that!
We flew over our to be house, our groundwork should start in a few weeks.

5/18/19

Wing torque, flaps

I need to find a way to get to the aircraft more often!

I attached the bolt that connect the back part of the wings and then torqued all wing bolts. I used about 170 and 820 inch pounds.

Then I attached the little fuel line from the tanks to the fuselage. After that I managed to connect the flap actuation. My flap motor runs in the wrong way, I will deal with that later.

Final task was checking my com radio, I could here coms but with very low volume. Hopefully just a configuration problem.





5/11/19

Wings

Another milestone. Wings are attached (not all bolts are in and no torque on any nuts)

I arrived at the airport early, unpacked some tools and supplies and then started working. First was removing the cowling again, the upper pins really caused trouble this time, must use better lube the next time.

Next was removing the lower spark plugs and letting out the preservative oil. Almost nothing came out of cylinder 2-4 but a lot from cylinder 1. Next was removing the oil, about 1/2 quart came out. Filled with 7 quarts of straight mineral oil.

Removed the plastics from the propeller, connected the main battery and rolled out the RV from the hangar. Now several EAA members started showing up, ran the starter motor with the lower plugs still out, almost no oil pressure on the first run but after letting the engine cool, I got pressure on the second 10-second run with the starter.

I had not gotten hold of or been able to manufacture any drift pins so I had not planned to install the wings today but with all helping hands around, I found two old worn 3/8 bolts and sanded them slightly and trial fitted them on the RV and lubed everything with grease.

Then we got to work, being five people it was surprisingly easy to get the bolts in, what I consider mild tapping with a plastic hammer while the others wiggled the wings was enough.

A big thank you to all who showed up!
