[TANKS] Re: Victor ESC's - to brake or not to brake ?
I have the Victors in my tank set to coast mode, too. When I used a Victor in my armored car, though, I used the brake mode. The rolling resistance of the tank is great enough to stop the vehicle quickly, that's not true for a wheeled vehicle. That fact led to an embarrassing incident in a parking lot J Live and learn.

[TANKS] Canon design, gas pressure and the likes
As has been discussed previously markers down-under are a problem, this means we need to home-make a "marker". This isn't all bad as it gives a chance to make things fit nicely as required into whatever turret/chassis you may be working on. I'm looking at either going the on-board compressor route like Chris Barthelson has done (see T030), or going with a HPA bottle. So I have a couple of questions which people with experience in pulling markers apart should be able to answer. This is all my understanding from limited reading on the subject, some, most or all may be wrong! A C02 system runs at about 600-800psi, HPA runs at about 3000psi, In either case I believe you need about 120psi to actually fire a paintball with a reservoir-like setup, but on a real marker w/C02 is it just using the 600psi and only opening the valve for a tiny amount of time? I'm guessing HPA would be similar, with the regulator bringing it down to a pressure similar to that of C02. I guess what I need to know is, what pressure, volume and length of time do I need to shoot gas in order to fire the ball? E.g. do we use 600psi for a smaller amount of time, or 120psi and a larger volume? Chris B has provided me with some good test data based on his 120psi compressor setup, but with C02 or regulated HPA I'm hoping to be able to get some pressure/volume data or advice out of commercial marker use?

You only need a slight incline to ensure gas at the top of the tank and since you *never* completely fill the tank with liquid, there will always be gas someplace in the tank.

On the US side I doubt that anything but Shermans and Sherman DD's were used in the initial assault with Stuarts coming later with the recce units. The British used Sherman DD's, Churchills of various types, the Royal Marine armoured support group used 95mm howitzer armed Centaurs and a few Tetrarchs were flown in by glider for good measure.

[TANKS] Bottle installation questions
Well, finally picked up a C02 bottle to be installed in the Sturmtiger. I'm using braided steel line for the hook-up from the bottle to the gun. It creates some interesting problems, but I think I have them solved by mounting the bottle under the rear deck by the batteries. That in itself is what I wanted to address. Since the bottle will now by oriented horizontally in the chassis, how important is an anti-siphon tube? It's a 20oz bottle so the neck is quite a bit higher than the bottom of the tank when it's laying horizontally. It will also be mounted to the track sponson which does have an ever so slight incline to it. Just trying to determine if I need to install an anti-siphon tube now. What do you guys think?

So I changed projects again... The M60 is sitting in the back room of the shop, and the Ti-67 is still in the research phase. I was looking at the little 1/72 matchbox tank models on my desk, and that led to more trouble in the shop. I have an M4 Sherman tank hull sitting in the shop now, with the bearings for the drive wheels in it, with all the drive junk waiting to go in. While the fiberglass on the plywood was curing, I started on the removable hull top (bottom of the sponsons & up lifts off). When I got the sponsons put together, I was getting excited about progress... and failed to pay attention. I now have a spare starboard M4 sponson if anyone needs one :) I also now have made a new one, and attached the top deck (where the turret sits), glacis plate, and the little piece that goes across the back between the tail ends of the sponsons. Very very cool. The VVSS suspension awaits only my cutting 10 more steel bars for the arms, and I can mount those suckers up, and then finish the tracks. Materials used so far: one 4'x4' sheet of 1/2" ply, some 'glass and epoxy. The motors, pulleys, and belts need mounted in the hull.

[TANKS] Re: Self Propelled Artillery?
With respect to the Ratte: "1000-ton Panzer By Gary Zimmer In June 1942 Hitler and Krupp discussed the feasibility of a one thousand ton super heavy tank. Unusually, Dr. Ferdinand Porsche does not seem to be involved, although this project would be right up his alley. As of December 29, 1942 some preliminary drawings at least had been done. By then the machine had been named 'Ratte' (Rat). If built, P.1000 would have dwarfed its little cousin, Maus. Intended to be 35m long, 14m wide and 11m high, and armed with an ex- Kreigsmarine turret with two 28cm SchiffsKanone C/28. In other words a triple turret similar to those used on the Graf Spee class, but without the centre gun. Each gun weighed 48.2 tons and had a barrel length of nearly 15m. Projectiles were 1.2m long, Panzersprenggranate (armour piercing) rounds weighing 330 kg each and containing 8.1kg of explosive, or 315kg Sprenggranate (high explosive) rounds containing 17.1kg of explosive. The maximum range of these guns was 42.5km (26 miles). Some sort of secondary anti-aircraft armament in the form of 2cm Flak guns was planned. One feature of the design, as indicated on the drawing, was the use of triple tracks, each individual track being 1.2m wide. Power was to have been eight Daimler marine engines (presumably E-boat), developed to produce a total 16,000 hp. There are some anomalies in the design of Ratte, as depicted. The amount of track in contact with the ground is inconsistent with the weight of 1000 tons, either it will have a ridiculously low ground pressure, meaning that all that track is not necessary; or it will be heavier than 1000 tons. If we imagine the centre hull between the tracks to be an armoured box, without worrying yet about the belly or roof, and 200mm thick (and that is a bit light on by battleship standards), it works out to be about 730 tons on its own. That doesn't leave a whole lot for suspension, tracks, engines, belly and deck armour. The pair of guns on their own would be another 100 tons, and we can assume that the turret would have to be armoured to at least 250mm. If we include the barbette, the turret should account for at least 380 tons, not counting guns, gun mounts and shell hoists. The ammunition stowage is anybody's guess, but bear in mind every three rounds adds another ton to the total weight. If Ratte was built, it would probably end up closer to 2000 tons." http://strangevehicles.greyfalcon.us/Landkreuzer%20P1000%20Ratte.htm "The greatest strength of the Ratte would have been its ability to single-handedly halt a major enemy offensive. It would have been slow and poor on the attack but the sight of a Ratte looming out of fog on a battlefield would have almost immediately scattered enemy ground forces. If they didn’t flee right away they would have once they realized their weapons were nearly useless against it. Make no mistake, the astronomical cost of building a Ratte would not have been offset by its strengths. Once deployed and used in combat, it was just a matter of time before enemy aircraft destroyed it. With such poor speed and the limitations of the terrain the Ratte would not have enjoyed the same advantages of a wide open sea as its naval counterparts. The Ratte could have turned the tide of a single battle at the cost of a campaign." http://strangevehicles.greyfalcon.us/mauspic/rat1.png Note the comparative size in this sketch above. A 35 meter long, 14 meter wide, 11 meter tall tank would scale down to 5.8 meters long, 2.3 meters wide, and 1.8 meters tall. In other words, MASSIVE. Built at 1/35th scale, it would still be a meter long. Brad --~--~-~--~~~---~--~~ You are currently subscribed to the "R/C Tank Combat" group.

Some may not remember but i posted something about a P1000 and P1500 awhile ago.

I reckon it wouldnt be practical in rc warfare. to big a target to hit. and probably slow. run out of batter quick im guessing. Let alone building it to support the torque needed to move it.
