Hmmm, I’ve got files I cobbled together for a Hanomag SS100, that bugger would pull a V2 rocket sot it should pull just about anything.

The V2 was moved empty, so it only weighed 3 tons if memory serves. Fuel wasn't added until just before firing due to the Oxygen being in liquid form, and the rest of it being somewhat dangerously volatile

Shame that, would have been better if they tried moving around fully fuelled, would have maybe helped bring a halt to things quicker.
But that aside, good info nonetheless.

Some of the fuel they used was pretty wicked stuff. Just for example, the stuff used for the ME-163 Komet was so volatile (T stoff and C stoff) they lost more pilots to accidents on the runway than they did to allied guns. Not only did the V2 use T stoff, it also used Z stoff, A stoff and B stoff. I just like the names, and can never remember what they all mean, but there was a lot of hydrogen peroxide being used. Anyway, the point is that none of it was the kind of stuff you'd want in a rocket on a trailer cruisin' down the road. Much better to add after the rocket is vertical and ready to go.

Here is the complete list of stoffs https://en.wikipedia.org/wiki/List_of_stoffs Hydrogen Peroxide and Hydrazine are particularly nasty.

Finished the details. Not a bad way to spend 6hrs in the evenings. Better that than watching 3 crappy films on netttfliiiixxx




The outer wheels are going to get a strip of rubber sheet so they run a bit smoother. More modern wheels coming soon when i find something i like based on real photos.

Extra features, the axle is hollow to allow a M3 threaded bar to be used to give extra strength and also the wheels will bolt on with nut. The wheels also have small 3mm ball races in them hidden in the back and small top covers will slip in to hide the wheel nuts.
The tow hitch will have a m3 bolt fitted to secure into our own design tow hitch. Ok that is not so real, but is works really well and articulates nicely. So its simple and strong.

I was thinking about a early Citroen P-107 to tow it around or maybe a Ost tracked vehicle....... time will tell. Now need to see if i can print one off for the weekend for another model exhibition

So who knows where to buy reels of ptfe tubing? i don't think i asked that before?
i want to have a reel of the stuff so i can stop buying silly little lengths from other people. quite expensive to do this, so i prefer 1 big up front. capricorn tube is nice, but i can live with the stck stuff

I’d guess anywhere that does pneumatics, I’d bet money that what we buy isn’t PTFE anyway, just nylon!

You're right.
There is real PTFE-Tube, rated up to 150°C - but very expensive.
Next Question: have they the right Diameter?
