As an opener for 2017, Blue Square Model’s Blitz Workshop series offers its towed fuel tank that contained the rocket juice used by the V-2.
From Wikipedia: During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-Stoff. In German, Stoff means roughly the same thing as English "stuff", both of which derive from the Old French word estoffe (meaning cloth or material). Stoff has as broad a range of meanings, ranging from "chemical substance" to "cloth", depending on the context.

B-Stoff Kessel Kw-.3500 I.Anhanger (B72017) is a full resin kit rendered in 1/72 scale. It is now available as a limited edition kit.

How can I be MORE specific??? Take a look here, in case you don't know what overhang is: LINK I hope it is better so:

size is ok, I know where is the problem - middle part of tank. boarder lines are wrong to close to the middle. So it looks like to short Good eye ilfil62 !

Ummm, pardon a Forum member living in the worlds vodka-belt (northern latitudes where vodka is consumed). A mixture of 75% ethanol and 25% water is very strong version of vodka (in Austria they have "Stroh 80" which is a rhum with 80% alcohol). Hydrazine on the other hand is something completely different: "Hydrazine is an inorganic compound with the chemical formula N2H4 (also written H2NNH2). A simple pnictogen hydride, it is a colorless flammable liquid with an ammonia-like odor. Hydrazine is highly toxic and dangerously unstable unless handled in solution. As of 2000, approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) were manufactured worldwide per year.[9] Hydrazine is mainly used as a foaming agent in preparing polymer foams, but significant applications also include its uses as a precursor to polymerization catalysts and pharmaceuticals. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion." Hydrazine needs to be handled in solution, i.e. hydrazine hydrate,"a 64% solution of hydrazine in water by weight" More info on Wikipedia, including a better typing of the chemical formula: LINK Maybe some exaggerations but here is a story about hydrazine used in dragracing: LINK / Robin

Checking my reference it says "...hydrazine or 75% ethanol...". Will that "or" make it right?

I had to check ... This article on Wikipedia: LINK claims that B-Stoff in WW II could be either Hydrazine or the ethanol/water cocktail This page claims that B-Stoff is the ethanol & water mix: LINK Useful listing of the vehicles by the way .... This page, on the other hand, claims that the B-Stoff used as rocket fuel was Hydrazine (ethanol not mentioned ...): LINK Maybe the easiest way would be to simply say B-Stoff, the second best option is to insert an 'or' but I would almost dare to say that when used for the V-2 rocket B-Stoff should be read as ethanol/water (it was in short supply ...). This page LINK also claims that hydrazine was used for the Me-163 so maybe the 'List of Stoffs' says Hydrazine as rocket fuel because of the Me-163. "Hydrazine was first used as a rocket fuel during World War II for the Messerschmitt Me 163B (the first rocket-powered fighter plane), under the code name B-Stoff (hydrazine hydrate). When mixed with methanol (M-Stoff) and water it was called C-Stoff.[citation needed]" This page LINK claims that B-Stoff (or hydrazinhydrat) was used as a catalyst for M-Stoff or T-Stoff. Since Hydrazine is an oxygene scavenger I don't think it can be used as a fuel without adding something more than oxygene. Some chemist will probably bash me over the head for this ... / Robin

Hello Robin, The first three links you posted were the same that I read through as I prepared the news article. My guess is that the Wiki contributor placed the operator "or" to be on the safe side (?) Here's another one: http://www.v2rocket.com/start/makeup/design.html. There's liquid oxygen that's added so I guess that takes care of the hydrazine as well if it was used instead. Anyways, I've taken out that bit on the mix so as not to add further to the cocktail of information out there. Thanks for bringing it up. Skål! Tat

Liquid oxygen and any kind of fuel makes a very potent mix. Liquid oxygen and ethanol makes a nice rocket fuel. Don't know why they added water, maybe as a coolant but it doesn't need any hydrazine. Skål och botten upp ! / Robin

Now we need one in 1/35th to go along with the newly-offered V-2 with truck and trailer.

Lead Warrior has released some 1/35th V-2 battery vehicles, (Opel Blitz B-Stoff and T-Stoff tankers, Sd.Kfz.7/3 Feuerleitpanzer) http://www.leadwarrior.com/list-lw.htm CustomScale (and Azimut...) has released the A-Stoff trailer : H.P.
