Nose weights redux
Posted by Don Stauffer on Wednesday, December 06, 2017 9:02 AM

Building a Revell Super Connie now.  At least the instructions say how much weight I need (15 gm).  But, cramming that much weight well forward in that streamlined nose is a big issue.  One of the main problems is packing factor.  Unless you have a cast solid weight, the effective density of the weight is reduced because spheres and other shaped objects cannot be packed together to fill 100% of the volume.  I forget what the packing factor of spheres is- I think it is around 75%.  And, by the laws of geometry, unintuitively, it does not depend on the size of the particle!  Using smaller spheres, it stays the same number.  With the price of kits rising a lot lately, seems to me they could include a cast weight on tri-gear planes!  We need to let kit mfgs know we would really appreciate them.

I build Tamiya's Me262, that came with a metal part to form the top of the wheel well.  It greatly eased to construction. No guessing if you got too much or too little.  Fitted where it was to be.   On airliners, even the proper ballast to lay in bottom of the fuseluge, and maybe the nose gear strut to take the weight.

Would you keep us posted on how the build goes? The Super Connie is one of my more coveted kits but the only one I can locate in on Amazon for $104 and that isn't going to happen. I'd love to see it reissued at the same time someone offers a totally new P-38 (are you listening Tamiya?).

If you keep an eye on eBay should be able to nab one for $ 70 or so. It's worth it.

The seller is wrong AFA the scale. That's a rebox of the old Revell L1049. It's at about 1/130 (box) scale. That one is desirable in TWA livery.

There is a Revell of Germany 1/144 Super G around, which is a rebox of a Minicraft kit.

I rarely use ebay so I didn't look. Thanks for the info.

Good grief!  I hadn't realized they were going for that much money!  Boy, I am glad I got mine when I did!

Unless the Connie is a grade above the normal minicraft kit, the Revell kit is definitely a step up.  Not sure a factor of 5, however.  I have built a number of the Minicraft airliners- not bad, but that Revell kit is really pretty nice.  Not sure I would pay over a hundred, though.  Maybe spring for the seventy, though.

I sent an e-mail to revell suggesting that they include nose weights in their kits. I received a reply from Revell saying that my suggestion was a good idea and that they would consider it. That was two years ago. Bang Head

Interesting.  Anyone know who handles this product?

I don't like the idea of using too much CA in one spot, and a two part catalyzed mix might raise thermal issues.  I suspect one would need a very slow setting adhesive.

I know you can get it from anyone that orders from Walthers (https://www.walthers.com/liquid-gravity-240g) or you can order it right from them.

Some kind of non-toxic metal sand. I suppose it might be useful to pour it onto plastic wrap inside the model. That might keep the CA from attacking the plastic.
