Great idea about adding the picture to conceal the weight bag.

The area  where I added the weight (flight engineers office) is about 5 inches from the landing gear. The engine cowlings are about 2 1/2 inches from the landing gear. That means that twice the amount of weight (one pound) would be required to prevent the plane from sitting on its tail. The closer the weight is located to the landing gear the more weight is required.

 

 
Yeah, I understand the fulcrum and lever effect, but I'm thinking about how you had to have weight in a visible area.  Your solution to cover it is great, but I'm just thinking about alternatives.  The forward end of the tunnel is only a little behind the engineer's station, so that's why I wondered whether it'd be useful to use that spot, too.  Well, I've got two in the stash, so I can experiment with them and see.

That means that twice the amount of weight (one pound total weight) would be required to prevent the plane from sitting on its tail.

I wonder if you can add weight to the engine cowlings?

...NOSE WEIGHTS

The main landing gear is located under engines two and three. There is a whole lot of plane behing the landing gear, so a lot of weight is required to keep the plane from being a tail sitter...

First I added weights to the underside of the cockpit floor. There really is not a lot of space for weights under the floor, so I decided to add weight in the flight engineer's area behind the pilots (outlined in blue). Once the fuselage is assembled this area is hidden from view...

Next I filled the bag with white glue to keep the shot from moving around.  I placed the bag into the model and noticed that the bag was visible through the opening in the wall behind the pilots and the flight engineer. Now what? I could paint it black, but I didn't like that solution. I looked on line for a photo of the wall behind the flight engineer. I printed the picture, cut out the image and glued it behind the opening. Problem solved...

I wonder if we can stick some or all of that weight into the access tunnel.  It'd be forward of the landing gear, and it'd be completely out of sight.  Same goes for putting weights in the engine nacelles.

My solution back in the day was to use a small machine screw, sandwiched into one of the front wheels, because it was fastened through a diorama base.  For a shelf model, of course, that's not really a solution.

Wow! ETA on the finish date? What's the weight of the lead shot in the flight engineer station?

 

I added almost half a pound of split shot weight to the nose. That does not include the weights glued to the underside of the cockpit floor.

Yes very clever idea about adding the picture.  This is going to be one fabulous model.

OK. In the stash: Way too much to build in one lifetime...

Well, I have been working on this model off and on for almost a year. I used 10 sheets of Bare Metal Foil. The only thing left to do is foil the bomb bay doors and landing gear doors. Next will be the final assembly. The following photo was taken last week. I included a P-51 to give you a sense of the size of the B-29.

Following are updates since my last post in July.

NOSE WEIGHTS

The main landing gear is located under engines two and three. There is a whole lot of plane behing the landing gear, so a lot of weight is required to keep the plane from being a tail sitter.

 

First I added weights to the underside of the cockpit floor. There really is not a lot of space for weights under the floor, so I decided to add weight in the flight engineer's area behind the pilots (outlined in blue). Once the fuselage is assembled this area is hidden from view.

 

 

I temporarily assembled the model including the landing gear. I then kept adding "Zig Zag" split shot that I purchased from Cabela's to a small plastic bag until the nose of the plane tipped down. The bag is located above the flight engineer's area. A lot of weight was required.

 

Next I filled the bag with white glue to keep the shot from moving around.  I placed the bag into the model and noticed that the bag was visible through the opening in the wall behind the pilots and the flight engineer. Now what? I could paint it black, but I didn't like that solution. I looked on line for a photo of the wall behind the flight engineer. I printed the picture, cut out the image and glued it behind the opening. Problem solved.

Finally, I glued the bag in place with white glue and used a wire to hold it in place just in case. I painted part of the  bag black so that it would not be visible when looking through the small side windows.
