North American B-25 Mitchell Batch Build in 1/72 Scale Part III

There are two challenges for this build – preventing the models from being tail-sitters and the nose art. My worst-case scenario for getting enough weight in the Mitchells was this glass-nosed B-25C – all the others will be strafers and therefore weight can be added far forward in the nose.
Here the fuselages have been closed up. At this point I sanded seams and re-scribed any lost panel lines as the model is easier to handle. I went over the re-scribed lines with MEK to remove any burrs.
The main gear legs are the fulcrum point, just like a see-saw. Any weight aft of the main gear legs contributes to the model being a tail-sitter, any forward helps keep the nose down. Adding weight loads the main gear, but contrary to popular belief if the balance is perfect the nose gear bears no weight at all.
My build is a marginal case, but I think I’ll be okay when all the parts are on. The model will stay where you put it, either on the tail or on the nose. I will leave a way to get more weight into the engineer’s station if I need to.
Hasegawa just says to “use ballast if not using support”, and waits until the final step to remind you. They do provide a step stool to prop up the tail if you need it. This is the nose for the B-25H, which is the best place to start as it is as far forward as you can go. I glue the BBs in place with 5-minute epoxy, which will flow out of the gun holes if not sealed off.
The BBs are epoxied in place. This is a good chunk of weight at the end of the nose, and is therefore more effective than anything added further aft.
The Hasegawa B-25H will not be a tail-sitter, I used about 65 BBs in all due to being able to use the nose.
