Deluxe Materials is a company I was not familiar with. Deluxe Materials is based out of the Great Britain and it certainly provides with quality supplies to the hobbyists in Great Britain and beyond.

Liquid Gravity is a weighting system that can be used for different applications, from preventing a model airplane being a tail sitter, to balancing an RC airplane or even to providing weight to the rolling stock of your railroad layout.

I am not sure what metal is used for the tiny little “BBs”, but it is not magnetic and after a few measurements I came up with a density of about 4.15 gr/cm³ (lead has a density of 11.3 gr/cm³ for comparison). Despite the lower density, “Liquid Gravity” it has a great advantage: it is nontoxic.

The Product

According to the manufacturer this stuff is a lightweight, non-shrinking scenic material for creating and casting realistic diorama groundwork. It dries without cracking, bonds to wood, plaster, plastic, foam and can be cut, sawn and filed to shape when dry without crumbling.

The Test

After carefully viewing the on line you-tube video I began by preparing an 8X10 oval basswood base. I then tried to roll the product into log shapes and let dry overnight. I believe my sample jar was a little dehydrated, as you can see in the photos my success rate was about 70%. I’m sure this could have been avoided by simply adding a little water. I found out later while experimenting that the product requires very little water as it melts quickly with just a few drops.

The Yak-1 kit originally manufactured by Accurate Miniatures and now re-boxed by Eduard is a fine little kit but could certainly use a bit of aftermarket sparkle with this Quickboost exhaust kit. The original kit parts are ok but lack the bored out exhaust stubs.

The Quickboost kit contains a pair of well molded exhaust parts in grey colored resin. Removal from the pour stub is easy by simply making a few scores with your favorite sharp hobby knife. Please be careful - it is easy to score through the part (ask me how I know), and slice the part in half. Once separated from the pour stubs, a few scrapes with my hobby blade cleaned up the part and I was able to place it relatively easily in the fuselage opening. These two parts have a good fit and it looks good when installed.
