@ TripleW, Probably won't put an Evo radial in this one as we do not have a size that will really work. The 35cc is too small and the 77 is a bit big. I will check and see though. Would be cool. We need about a 60cc alternative for a model this size.
Videographer should hit the shop in about 10 minutes and we are shooting again today. So I am building again today and tomorrow. Look for some updates on the bird tonight and Friday.
Thanks for the support everyone and moderators. We will keep it going the way it was started.
I also ordered up some of the zinc chromate yellow primmer from Aircraft Spruce and Specialties. Should be here in a couple of days. I am excited to report on this stuff once it arrives!!

John,
Great assembly thread. (I did not say build) I have purchased from Horizon but not exclusively and I do appreaciate your links to products I may not have in my shop. If I was to be doing my first build your references would be very helpful. I would still comparison shop regardless of any reference to one hobby org. or another plus hitting up the local shops so personally I think the post of opposition has not been of any value to your assembly thread for beggining or intermediate flyers. Too Bad... Great job so far and typically I don't go for ARFS but you have provided some ideas outside of the product that I can apply to my other builds. Keep it coming, everything looks good so far and thanks for sparking some ideas for other applications.

First, love the thread. Please keep posting the links for parts and gear. It really helps newbees like me save time searching. Although this model is above my current skill level, it is going to the top of my wish list. My Dad flew one of these birds so one will end up in my hanger (basement) soon.
Thanks John, these threads are a great help.

So it was time to install the tail wheel assembly. The Robart tail wheel assembly is a simple bolt in process and the sequence here follows the manual pretty much verbatim. Here we go.
pic #1 shows the tail wheel unit with an 18 inch extension added ready to bolt in. If you were using the pneumatic tail wheel you would add your airlines as specified in the manual.
pic #2 shows removing the steering arm and grinding a flat spot for the set screw. This uses the traditional cutoff wheel from Dubro to grind the flat spot. Put it back together with threadlock.
http://www.horizonhobby.com/products...N4485-_-DUB353
pic #3 shows the Dubro 1/16" threaded ball links installed. These are called out for in the manual if you install the retractable tail wheel. Bolt them in place and use threadlock.
http://www.horizonhobby.com/products...N4485-_-DUB190
pic #4 shows the installation of the steering cables around the ball links. This method gives a simple system that does not get tangled up like clevis's sometimes can.
pic #5 shows the removal of the aft bulkhead that the fixed tail wheel assembly needs. If installing retracts you must cut this out. A simple Zona Saw helps in this operation.

Next you will bolt the tail wheel in place and work the cover.
These pics show the tail wheel bolted in place and also in the extended and retracted position. Pretty simple process, just (4) 4-40 bolts and some threadlock and it is done. All works well and is clear. Next will be the tail wheel cover.

You will need to retract the tail wheel to fit the cover first and then will need to extend and retract multiple times during the cover process.
You will want to read through and follow the pictures a couple of times to understand what I am trying to do here.
pic #1 shows the tail wheel retracted and the cover placed on top to see if any trimming of the cover is necessary.
pic #2 shows the tail wheel extended again and a piece of masking tape located across the opening in front of the tail wheel.
pic #3 shows a couple of marks locating the width of the tail wheel unit on the tape.
pic #4 shows the tape in place on the cover. Do this by cutting the tape in the middle of the two marks you made and locate the cover in place over the opening. Now push the tape down on the cover and trim it from the fuse sides.

Now remove the cover from the model. I laid some masking tape down for the retraction angle towards the back. This is just to begin the cut as an outline.
pic #1 shows the beginning of the cut using a perma-grit pancake fine cutting tool available from BVM.
http://shopbvmjets.com/zencart/index...s3kr06brva5p17
pic #2 and #3 show the basic outline of the cut and the cover fitted back over the opening. It is not open enough to retract the tail wheel yet. That will come. This is just to work the front of the opening. Go slow here and take your time.
pic #4 shows the tail wheel retracted and the cover being marked for the rest of the opening for the tail wheel itself. The tail wheel unit was retracted with the cover removed for this step.
pic #5, #6, and #7 show the opening complete and finished. You should now be able to extend and retract the tail wheel through the opening holding the cover in place.

RE: Hangar 9 30cc P-47 Build Thread
If the tail wheel will go through the opening cleanly with clearance all around so it will not get caught then we can add the mounting screws to the cover. I used a 5/64" drill bit to drill the holes in the cover first. I then followed with a 1/16" drill bit to drill the holes in the fuselage for the screws.
pic #1 shows some masking tape with a mark showing where the mounting flange is for the center screw on one side.
pic #2 shows some masking tape with a mark showing where the mounting flange is for the center screw on the other side.
All other screws are in the front corners or at the back end. make sure you push the cover down for a tight fit when drilling the screw holes and drill one at a time and install the screw.
pic #3 shows what I forgot to do before installing the tail wheel. I forgot to paint it. So with some tape and paper I masked off the area and pulled out the Testors Metallic Silver spray paint and gave it a couple of light coats. I also masked off the wheel and shot the inner wheel hub silver on one side and flat black on the other. I shot the spoked cover silver as well.
pic #4 shows the completed unit all done.

John,
I have been drooling over this bird ever since it was put up on the Horizon site and have been waiting for the public release. Will Horizon be carrying the Robart electric retracts that you are using for this build? Also will you be installing the inner gear doors on the mains? When will the video be posted?
Your bird looks great so far keep those posts coming!

RE: Hangar 9 30cc P-47 Build Thread
Time to move on to the main hatch. I found the main hatch to be a bit small when fit to the model. You can see from pic #1 and #2 that it is 1/8" too short. When the hatch is installed you can move it forward or backwards 1/8 of an inch. This is being addressed with the manufacturer at this time. This segment will show you how easy it is to fix. Now one would say everything should be perfect, but let’s face it that sometimes doesn't happen. The team does all it can to ensure the highest quality but on occasion things happen. So here is the easy fix.
pic #1 and #2 show the gap at either the front or back of the hatch. When the hatch is latched you can slide it for or aft to show the gap at either end.
pic #3 shows a piece of 1/8" balsa sheet placed in between the hatch and the front bulkhead. I selected to add it here as it will be covered by the cowling.
pic #4 shows the mark to match the hatch and the piece cut out for final trimming.
pic #5 shows placing the balsa on the hatch front to find the location of the wooden dowels. We will make some 1/4" holes for the dowels to go through.
pic #6 and #7 show the piece fitted in place and the hatch in place. Sand very carefully to match the outline of the hatch.

pic #1 shows how this area is covered under the cowling flaps. The choice to cover it is yours. I do highly recommend sealing it at the least. I covered mine just to be sure.
pic #2 shows the front of the hatch recovered and installed without the cowling.
pic #3 shows the hatch installed and the cowling held up in place. The hatch now fits like a professional built it.

RE: Hangar 9 30cc P-47 Build Thread
While I was working on the hatch I decided to begin the area under the canopy. As it comes it is covered in aluminum and olive drab. You can just glue the canopy on and put a pilot in it but this model begs for more. Another option would be to paint the area under the canopy flat black. This will dress it up a bit but I wanted to do more. It is a big warbird and the canopy is pretty good size.
I pulled out a book on the P-47 and decided to get to work. My area behind the canopy is not totally correct and that was never the intent. It does however simulate some of the sliding canopy mechanism from the full scale that was clearly visible in the cockpit area. So we have discussed the Plastruct before in this thread on the main gear doors. We will be using the .010" plastic sheet for detail work.
pic #1 shows some masking tape laid down and the canopy then set on top and I have gone around the canopy with a pen. This is to mark out the outline of the canopy so I can cut the covering away to begin detailing.
pic #2 shows the covering cut away. Cut to about 1/8 or 3/16" inside of your line.
pic #3 and #4 show the .010" plastic sheet glued down in the back area with some rivet detail added. You can also see the track that the canopy slider would slide on the real aircraft. This is all made from Plastruct materials.
pic #5 shows the sides using the .010" sheet and some rivet detail. This will enhance the look of the model ten fold when complete.
The track is some "C" channel material that is listed here.
http://www.horizonhobbytrains.com/pr...485-_-PLS90584
The center of the track is some straight stock that is listed here.
http://www.horizonhobbytrains.com/pr...485-_-PLS90744
The 3 braces that hold the track are from .040 plastic sheets listed here.
http://www.horizonhobbytrains.com/pr...485-_-PLS91104
The black brace is a piece of 1/8" plywood that is cut and sanded to shape and then filled and painted.
All rivets are done with the syringe kit listed earlier in the thread. Paint is the Leafy Green listed earlier in the thread.
The flat Black is Testors Flat Black spray.
The dirt and light scratching weathering is done with silver paint and black chalk. These methods will be discussed in the weathering section of the build coming soon.

John R.
I am intrigued as to how you finished off your scale wheels on the P-47 thread. How did you paint the six dark black cutout portions in the otherwise silver wheels? Did you mask the wheel off or does the wheel disassemble so that you can easily paint the inside of the wheel? Are these Robart wheels?
I see this type of scale upgrade applicable to the wheels on most all WWII aircraft and many jet airplanes as well.
Thanks for your article. I look forward to the remaining sections as they come along. Your fit and finish on the whel wells and gear doors is superb.

Hey John,
The spoked hub comes off. The wheels I show in the build are the ones that come in the kit. I painted the inside of the hub flat black and then sprayed the outer spoke "hub cap" silver.
I will show some Robart wheel very soon, probably the next batch of updates.
Glad you like the build. The gear door fit is due to the kit and is very nice. All in all everythign is fitting well.
Stay tuned!!!

Time to finish off the cockpit area of the top hatch.
pic #1 shows the front dash area that needs to be cut away for the gun sight.
pic #2 shows the area cut away and ready for the plastic sheeting.
pic #3 is from one of my P-47 books showing the optical gun sight. The P-47 had no real dash, but on the model it does as this is much easy to reproduce in mass production. So we will cover the area with some sheet plastic and paint flat black to get the effect. I do want to try to give an illusion of the gun sight, so we will follow the book picture to reproduce one.

We will now begin to build a basic gun sight for the cockpit. I used some cardboard rocket tube material and some Plastruct tubing and C channel. Some clear .040 ABS sheet for the actual sight. Follow the pictures below to build the sight. All of this is just a free hand program to make something quickly that replicates to a basic degree the original sight. The entire amount of work for the area on the hatch was about 2 hours. This includes painting and riveting. Once complete paint the sight silver. The holder that holds the sight to the frame work is balsa with some .010 sheet glued to it on the top to add strength. The front area is sheeted with .010" plastic sheet and riveted and painted flat black.

Next we needed a pilot. The pilot I chose is one from one of the military hobby companies. A main company is "Elite Force" and they currently have the George Bush fighter pilot available. You can find these all day long on EBay. I strapped the pilot into the cockpit tub using some velcro around his waist. The cockpit tub secures into the model with (2) 4-40 bolts in the back and has tabs at the front that key into the main airframe. With this pilot he was just a bit short so I used his parachute under his butt to set the correct height in the seat.
Once all fit and set I dropped the cockpit into the fuselage and bolted it in place. Test fit the top hatch in place and set the canopy in place to check the pilot height. When everything looks good you can glue the canopy to the hatch with 5 miinute epoxy or Canopy glue.

RE: Hangar 9 30cc P-47 Build Thread
Great work John,
A couple of years ago I purchased an 8th Air Force action figure named "William Bowman" to fly in my Top Flite GS P-47. He was super accurate right down to the oxygen mask. A bit pricey at $ 90.00 but worth every penny. He still pops up now and then on E-Bay.
We are following your build with great interest. Our WWII group has four of these ships back ordered . Three will be electric powered and all will carry the new electric retracts!
Regards,
Doug

Maybe I'm overly suspicious, but the ''pictures'' of the retracts shown on that website look like computer generated graphics. I don't find that very reassuring especially for a ''pre-order''. Who knows what you will actually receive. Wingspan lists a USA address on the website, which is good, and they have some other interesting things too. Hopefully, they will be OK, and the retracts are well-made, but I learned along time ago that cutting costs on an important item like retracts is not worth it.
