Thank you guys, didn't gave up on it yet
I was quite annoyed yesterday. Iam not "saving" when buying equipment. I thought that the Jet-Tronics electronic valve will be the best and will save me setup issues and weight.
It turned out to be headache, with the speed control option unusable and now Ihave this "leak" when retracted.
One thing I was thinking of yesterday night was that maybe, when retracted, the wheel touch the bay floor before the cylinder reach the end point and this may cause some of the issues with the air keep on "leaking".
Iwill need to investigate this further.

Jose - may I ask what is the brown covering on your aileron?

Brown is actually sand RLM 79, the upper color of desert scheme. I built a new wing but the ailerons, flaps , etc are from the prototype model. JG

Finally recovered enough to face the Me-109 again. Ihad a nasty flu.

Today I was looking into the retracts air leak at the "retracted" position.
Iadded washers to all mounting screws (between the wood and the gear) of the right retract (which Iwas suspecting the wheel centre pin touching the wing skin).
To do that, Ihad to cut holes in the skin to reach the screws.

Iam happy to say that this has resolved the issue. Imade quite a few retracts and extracts and could not repeat the problem.
Ialso somehow managed to eliminate the programmable "slow down" of the valve which was wasting huge amount of air. The problem is that Idon't know how I did it.
Ipressurised the system to 100 PSIand will leave it for 24 hours to check for leaks.

Ialso received the Hitec HS-5085MG Mini-Servos Iordered for the radiator flaps. Iwill look at a way to integrate them soon.

Jose - Do you know how demoralising it is to see you build the wing that quick?
Ihad no chance to congratulate you on the first parts for the Ta-152. Looking very good. You are not letting us enjoy the beauty of it with the small photos you post.

Hello Eran,

having built a "few" wings in the past helps! Actually it's been slow finishing the rebuilt 109, because of the Ta152 project and the moving across states! Talking big time stress @!

YOur gear mount: I suggest opening the area were the retract mounts to the wing. You want to be able to pull the retract out without disturbing the surface skin. If you have a bad landing and the gear pulls back, you don't want the skin to be pulled back with it. Don't ask me how I know this. JUst cut a small cover plate with fliteskin and mount it around the gear frame with small screws or tack with cyano so you can pull easlily when take the gear apart.

Hi Jose

Any chance you have a photo of this area on your wing so Ican see what you did?
Idon't like the idea of ripping the skin...

It is time to gain some momentum back into this build.

The pressure test went very well. Ihad ~90PSI after 48 hours.
After that Imanaged to retract few times with the remaining pressure without a problem.
If Ijust had an idea how to fix the bay walls... This will have to wait for inspiration.

After this success, I removed all the radio gear from the wing and am back to the radiator flaps.
With the time left today all I managed to do was to hinge the second radiator and the flap.
Now both are ready for servo installation.

Unfortunately didn't have the time I thought I will have today.
All I managed to do was to have a first look at how to position the mini servo in the radiator.
I am not sure yet how to attach is so it will sit as low as possible, Iwas even considering using silicon to attach it directly to the fibreglass.

You can attach with silicon glue directly to the glass, should work pretty good. Why did you want ti use separate servos for the iner flaps?

I went with servos in the radiator because I cannot get the torque rod to operate the flap satisfactory.
I spent few hours trying different length and geometry push-rods and concluded that I must have done something wrong. Probably the angle of the 4-40 bolt attached to the torque rod.

erans,

What exactly was happening? Was it binding or flexing?

Jose - No binding or flexing, but could not get full movement holding "up" flap against the wing and proper "down" from the maximum throw on the screw attached to the torque rod.
Ithink that the screw is too "leaning back" in the spar web direction and I do not get it to push the control rod in the correct angle.

Anyway, this is now resolved with the additional servos. The last 3 photos show the 3 position flap.
The only down side (except of the additional weight)is that I am now using all the available 11 channels (avoiding Y leads).

Nothing wrong with it, but it is easier to set up servo throw with servo per channel.
If I have to I will use Y leads.

SInce both flaps require the same throw, that means twice the amount of work.........[]

I think I understand ya erans. You will have the ability to dial each one individually, and yes that does seem like a nice ability after fiddling with mine. It took a bit to get mine done, but I'm glad to have them all on one flap servo in the end.

How excited was my 5 years old daughter to open the mail today (OK, I was too) .
In the large box arrived my Swiss pilot (named by my daughter "Hans"), made by Scale Aircrew Supplies in the UK.

When Icontacted Mark from Scale Aircrew Supplies few weeks ago, all I had in mind was to get something "good enough". I am not into scale to a level requiring too much of an accuracy.
Iwould have been happy enough with the German pilot that he already had as stock item.
Lucky for me, this was not good enough for Mark, who did some research and made this amazing pilot from different bits and pieces he had, to better represent Swiss Me-109 pilot from circa 1943 (and he custom made the seat parachute).

On top of looking awesome, the pilot is much lighter then Iexpected. You can probably tell that Iam very impressed.

As you can see, Hans was not impressed at all to see his empty "office". It will be a while before he get it furnished,
Talking about the cockpit, I cannot find 1/5 scale Me-109 cockpit "side panels" and a seat.
If anyone know where Ican get them (I have the front instrument panel from Jose), please let me know.

Ialso started to work on control rods for the flaps servos moving the torque rod, but was interrupted before I had time to get anything done.
More hopefully coming soon.

Eran

I got few free minutes, so finally connected the wing flap servos.
In the photo you can see the 3 position flaps / slats, currently utilising full throw.
Obviously nothing to see with the slats as I still have no idea how to connect them, but I can see the rods moving

Busier the expected weekend, so nowhere the amount of progress compared to what I planned.

I think I have a solution to how to mount the radiators. I made balsa mounting plates with blind nuts.
I glued them to the ribs and the wing skin (the mounts are longer then the hole I made in the skin).
Iwill be using 10-32 plastic wing mounting bolts and small amount of silicon all around the fibreglass radiator.
This will allow to maintain the mini servos if needed by cutting the silicon and opening the bolts.

Itook Hans, my pilot, to the airfield today, Everybody who saw it were very impressed.

I'm still where I left off....[]

My 3 year old has been diagnosed with autistic like behavior. Basically he doesn't talk much, he's your basic happy little boy(just turned three), but he acts like he's only two(in some areas) Doctors are hopefull that it's just a "delay" in learning, but my wife and I are being very proactive and have 3 different therapists working with him for an hour, twice a week. This keeps me pretty busy, but I still find time here and there, just not enough to get much done.

It's one reason for me trying to work on the FW190 I picked up, as it's not a show piece, and is abit more relaxed to deal with at times.

Casey,

Best wishes for your little guy. I have a 12 year old who was diagnosed with Autism when he was three as well. Long story short, he had lots of help from various types of therapists (occupational, speach, physical, etc.) plus my wife quit her job so she could stay home with him and basically provide therapy around the clock. It took some sacrifice for sure but our little guy's diagnosis was officially lifted a couple of years ago. He still has some minor issues, mostly social in nature, but in almost every respect he is a pretty typical 12 year old kid these days. I thank God, my wife, and all those therapists every day for that! Keep your chin up and don't hesitate to drop me a note if you have questions that my wife and I may be able to help with.

Casey - Ihope all comes out good with your son, these type of events put everything in perspective.

Iwas not aware of your refurb thread, Ihave just subscribed :-)

Iwas looking at a place to buy the cockpit kit, but could not easily find a place that have it.
Any chance you remember where you got it from?
