Master Series P47 - with flaps and static gear

Good morning All,
I am starting this thread to show how I interpreted the wheel mounting and how I am adding flaps to the new P47.

I noticed the square pattern on the wing bottom, and the squares to be cut from foam and plywood.
I have the parts laid out here in what I think the intended stack order was...

I am guessing that the exit hole for the wire is to be on the front corner on the wing center side, though if the hub is inward facing I'd flip this around to exit on the outer side.
The solid board on top to add strength above the bent wire, and two foam core boards to brace against the top wing skin.

I'll look for some appropriate sized wheels around here and post when I get the wires bent.

Now on the flap side of things my methods are sort of hand-fabricated.
I have the flap outline drawn on the pattern here, the side spacing is 15mm from each end of the trailing edge.

The attached PDF file is a scan of my pattern to trace here, the hinge just extends off the page to intersect with the 15mm offset on the outer cut.
Roughly, this page overlays like this:

The control horn lines are perpendicular-ish to the hinge line. I used pencil on paper (traced on both sides of the paper) to transfer the pattern from one side to the other.

Once the pattern is cut into the foam, before the wing spars are glued in, I make the pockets for the servos.

With the spar in place, not glued yet makes this easier, draw a straight line up from the control horn slot and place a servo so the arm is in line with that line and close to the inside of the rear spar.
I traced around the servo here so I could carve out the foam on top but leaving the outside paper. The carving is easier with the spar out of the way.

Next I cut a small hole in the paper where the control arm would stick through.

The servo fits nicely. If you glue it in now with the arm sticking through the next step will be harder, so do this right before the top wing cover goes on.

The next step, not sure if its entirely necessary yet, but with this thin piece sticking out I thought a skewer would help strengthen this area...
flap2.jpg

Its a little tricky, but if you hold the foam flat on the edge of a table with your hand on top you can persuade a skewer through the foam between the papers.
I'd suggest practicing on a couple of scrap pieces first.
I went just past the rear spar with the sticks.

Once the stick is in the servo with centered arm can be glued in.

This will leave some controls hanging below the wing, which is why I wanted to figure out the wheel setup.

Let me know if you have any feedback on this post format, or if you have questions on my process so far.
I'll keep you posted on progress as it goes along.

I admire you taking on a P-47 SCRATCHBUILD!!! 😳😎😎
Something I couldn't do without a trip to the Hospital!! πŸ˜†
I was wondering how to get Gear on it. I can't do belly landers...

Having a little trouble with fuselage skin 1, the part that goes between the one with the cowl flappy things and the big fuselage piece. It doesn't quite fit around former #3 or #4. Might need to cut my own skin to fit this part or section it and patch in a little rectangle.

I am using the tiled plans, I wonder if this object got scaled a little differently. We will persevere, we will fly.

I'm pretty adaptable, so it wasn't a problem. Thanks for the input.
Got the razorback fuse done tonight, and have the nose ready to do a bubbletop too (I wanted both, haha). Some of my seams could be a little better, I ran out of the big glue sticks and had to make do with my tiny glue gun.

I got a little wrinkly at the back of the canopy, if I get a chance to do another I would try forming the razorback as close to the finished shape as possible before gluing.

Happy Thanksgiving!

I got a little build time in while the big table was out. These beauties are still coming together πŸ‘
Happy Thanksgiving guys!!
I'm AMAZED that you're able to Scratchbuild on that level. You should be proud! I know I'm very impressed with your skills. Especially hand cutting all those parts, that had to be nearly perfect!
Hope all of you had a great Holiday. We DIDN'T. 😞

Sorry if I may seem bitter and angry lately... I'm EXHAUSTED! I don't think I slept for 3 days.

It's OK, we didn't miss anything.
NO THANKSGIVING. Couldn't afford Turkey. Couldn't afford Stuffing, Mashed Potatoes, Green Beans, Cranberry Sauce, Pumpkin Pie......
Freaking NOTHING!! 😭😳😞
Yup, the Year without a Thanksgiving... It's also going to be the year without a CHRISTMAS

Second year in a row. I didn't bother mentioning it, because if NOBODY (except ONE) had the Heart to help a poor little Boy who's been severely burned and DESPERATELY needs things around the House...
Then certainly nobody is going to help us have Thanksgiving dinner.
Frankly, if we actually DID receive any help, I'd rather it go to my Grandson. Turkey is overrated!

The GOOD news, Greyson is stable and beginning to heal. His Neck is only a few small pink spots. His Back Will take longer... That area the Doctor calls 2nd degree + burns.
Fortunately, he STILL had Stem Cells left!! πŸ‘πŸ‘
Some Babies keep Stem Cells for up to 3 years. He is living proof WHY WE NEED STEM CELL RESEARCH!!! Nothing short of Miraculous!

He was released from the Hospital - but can't stay here, because NOBODY helped us get him a Bed, new Clothes and a professional cleaning of this DUMP. He NEEDS all that because his burns are so bad, he's extremely prone to serious infections.
NO.... He has to stay with his bitter, other Grandma. (Who WOULDN'T help us because she's greedy and loves that she can have him all to herself)
He CRIED because he wanted his favorite Gampy!! πŸ˜­πŸ’”πŸ’” Shattered my Heart.

I guess that the Community at large is completely DONE with helping us, no matter WHAT! Thanks to a RUMOR.
Sadly we can't help ourselves.

Amazingly, there was ONE incredible Person who PayPaled me some money, that DID help him, and even his baby Brother with Formula and some supplies. But we need MORE than I could possibly ask any One Person for...
At least $400. I just can't ask.

But, IF 9 or 10 People could give up buying ONE NEW Kit, Battery, Tool or whatever each - that would be enough to help us...
To help Greyson!
But I realize that's too much to ask...

This is NOT a Scam! Not a business or scheme. Sadly this is my real life.
I have lost all Faith in Humanity. I wouldn't believe this if it was happening to anyone else!

I'm sorry for even bringing this up. If I don't vent somewhere, I'll completely lose it. My Family needs me to be strong.

Back to a happier, more positive note...
Someone NEEDS to make 3D Printed Cowls for this! πŸ‘πŸ‘
This level of Plane DESERVES that level of detail.

I did hand-cut most of these pieces, though I cheated a little bit on some of the small pieces. I thankfully have access to a little 6x12" laser machine, I used it to cut the small wood parts, the battery hatch parts, and the foam fuselage former shapes.
I like the hand finished quality of the hand cut parts, but the laser saved me a couple days of cutting parts out :D

Update - I got a couple of flite-test radial motors for the P-47's on the store's black Friday deal. I got some 2.75" foam wheels so I can assemble the gear parts this week. This size seems to look good with the wheel side "fairings" in the plans.
I haven't had loads of time to play over the last couple weeks, but I cant wait to fly these!

On an unrelated topic, I have a secret project that is more ground-based. I have done some 1/24 scale slot car drag racing, and I had this 30mm EDF laying around. I will be testing this over the winter...
