Sorry about the lengthy reply about the b-B-26...
I was going to do a photo shoot of the progress. but shyness go the better of me. The G model was going to be a trial run for a number of things. (That's why there are no guns).
I have never weighed the nose weights. So far I have made 4 B-26 with another one on build (See photo). Two have had collapsed nose wheels because of the weight.
To keep the weight to a minimum I now make the missing bomb aimer bulk head from sheet lead (roof lead) and line the inner nose wheel area with lead side walls. Another sheet of lead is formed and glued to the rear of the back cabin wall (Radio room). The model will only just stay on the nose wheel and will tail sit very easily. The model then weighs 250gms and the C of G is correct for standing on the nose wheel. That means there must by 125 gms ahead of main wheels. 80-100gms seems about the right figure for the lead. (Bear in mind how far forward my weights are, the kit suggest to put them in the radio compartment). I also replace the nose wheel main strut with brass tube.
if you are going to build one I can recommend the B-26 as probably the easiest model to rescribe, I always use cheap masking tape for scribing. If two or three pieces of tape are stuck on top on each other to make the tape thicker, then the tape is cut into 5mm strips it can be contoured around most curves easily. The adhesive is a lot stronger than, and lasts longer than dymo and can be discard easily. Any scribing tool, if held lightly will easily follow the tape. One roll of 2" masking tape has lasted 3 years so far and about 20 rescribed models.
The B-26 suffers from a number of known fit problems that I know of. The engine nacelles, the cowlings, the canopy and the tail gunner position. I have found that if the engine nacelles are glued together while they are being glued to to the lower wing, the problems with poor nacelle fit can be overcome. Once the nacelles are dry the top wing halves can be fitted. My latest B-26 did not need any filler on the nacelles. Event the nacelle rear part fitted without filler.
Take care when fitting the wings to the fuselage. Two of mine have anhedral despite the spars. (One model has a 8 swg piano wire rod acting as main spar to try to keep the wings straight).
The cowling tops don't fit they are about 1mm too small. An easy fix is to stick a piece of 1mm strip in between the top joint. Once fitted the cowling will fit spot on.
I find that the worst problem is always the tail gunner glazing. I now remove the fin and fit the glazing and tailplane together to make a parts fit something like. it still needs a lot of filler though.
The canopy never seems to fit really neatly. I cured this on the latest model by sanding off all the outer detail and sanding the canopy flush with the fusleage. It was then polished back to clarity. I then bought the Eduard Mask set and masked off the frameless canopy. The frames were the effectively formed by the paint thickness of teh interior green and the Alclad. (see photo).
I would recommend that anyone should try to aluminiun foil the Marauder . It really is adoddle. Standard kitchen foil will bend around all the B-26 curves. If you buy different foils from different stores and use both sides for different panels they show exactly the same effect at the real thing. No two foils are alike. (The more expensive foils are better for the compound curves). The adhesive is Faber Size, which is normally used for leaf metals. Simply paste/sponge on the foil, leave for 30 minutes and hey presto sticky back foil. No glue lumps either. The model MUST be clean and with smooth seams. I found that my covering the pasted foil with kitchen grease proof paper keeps the dust and hairs off while the glue is drying. Pasted foil can be stored an used for 48 hours or so without problems.
The next B-26 model shown below is currenlty under construction. This is being built with a home made tail gunner position and Alclad paint.
Hope this encourages someone else to build a B-26. It is a most beautiful aircraft.
I have an AMT B-26B yet to be built. Has anyone got any comments about that model?
