I went with "Eileen". I am partial to olive drab on warbirds, although, I believe the original used RAF colors. Robart missed the colors on this one by a wide margin.

Yes, i noticed that on their website. Well, can't wait for some pictures.
Especially rivet details etc. What engine will you install?

Strtnlevel, do you have pics yet of your P-47? I would love to see them.
It's been almost a month since you posted last.

As you can see, just getting started hinging surfaces. Very tedious on the elevators. Not more blocking to fasten the horns to. I'll try to keep posting as I go along.

Great Pics! Looks like a nice arf. Most of the work is done.
The detailing looks nice also. Thanks for the pics. What engine
are you going with? You should do a thread on the build, I know
alot of other members would be interested.

RE: Anyone Have a Robart P-47 yet?
Well this seems like a good place for me to jump in with my Robart P-47 build. I have the “No Guts No Glory†version. I am assuming that most of us do not have instructions yet, but I have gleaned some helpful information from Dennis Crooks. Passing it on in this forum should get things going.
I am starting off with the stabs as I think this is probably the most complex task to deal with. I always like to work this way. After this, things should be more straight forward. The first thing I noticed was that the internal ribs where the servos mount were not in same place on each stab. One was out about ¼ inch and at a different angle. The servo mount was also installed with the opening up against the spar so you could not even put a servo in. I do not mean for this to be a criticism, but rather a heads up when things don’t work. Maybe it is just my kit with this problem. I cut out the bad rib with my dremel and made a new rib to fit.
I also noticed that the hinge point seems to be setup at the back of the stab spar. If you put the hinges here, the elevator will not give you enough travel. You will need to move this point out 3/8 inch. I used brass tubing to strengthen the Robart hinge and epoxied them together. With a marker, I drew a line on each unit 3/8 inch from the hinge point. This made it easy to ensure that the hinge line was straight. Now it was time to recess the elevator 3/8 inch to accommodate the protruding hinge point. A drill bit would be sure to do damage here, so I used a dremel bit and measured a line at 3/8. This made a nice pocket for the hinge to move. It is also very easy to control the bit and get an accurate depth. The slot also does not show when everything is assembled.

For the control horns, I used TamJets. This was a tip from Dennis. You will notice that the control horn will end up exactly where the hinge is. You will need to cut some of the horn off in order to fit. This task is rather easy as there is a nice balsa block at this point, and with a bit of dremel work you will have a nice pocket to epoxy the horn into.
Hope all this helps.

Well I am glad that someone is looking at this thread. I can not believe that with potentially 50 of these ARF’s out there, that there is so little being said. I started putting some of my build on line to see if it would spark any interest. I have a good bit of the firewall and cowl mount in place, and I have to say that I am pleased with the progress. I will post as soon as I get some pics.

RE: Anyone Have a Robart P-47 yet?
This turned out to be quite the project! This is definitely not an ARF! It is highly prefabricated, but, definitely not an ARF. The lack of engineering is everywhere. Perhaps it will get better on the next production run. I appreciate the others who have posted here, I found it very helpful in solving the hinging problem. I went a step further and added hardwood blocking in the horizontal stab and the elevator. Very time consuming but, I think, very necessary. Found another surprise today as I removed the servo covers for the flap servos. The factory mounts are one and one-half inches below the surface of the wing. I fabricated a lite-ply mount and glued it on top the existing. This is not for the typical ARF guy as it is more more than just an assembly project. It is a beautiful model, however, and having flown one for a few minutes, I can tell you it's a wonderful flyer as well. But, for the amount of money spent, I think it is a bit overpriced. Still hoping to have it ready for the Scale Masters next month. I'll post pix when I can.

From what I have seen so far this plane looks great.
Do you guys think the Moki/RCS 150 radial engine will fit in the cowl?
If the model could handle the weight it would be a sweet combination..

RE: Anyone Have a Robart P-47 yet?
Just for starts, I need to recomend the appropriate method for mounting the wheels. There is no need to use wheel collars. As you can see from the photos, the pin goes in from the outside of the wheel and the set screw is used to lock the axel. When you have this in place, mark and grind a notch in the axel so that the set screw will have a good hold, and the axel will not back out. I use the purple thread lock on all fasteners to ensure that they do not come undone. After this is done, cut off the bit of axel that sticks out.
