JS3 Hovertank

[Scooterman]

Knocking the dust from the modeling bench..........

1/72 Trumpeter JS3m turret on some sort of anime hoverbike thingie that Rotorhead TX gave me. Barrel extended a bit, Model Master RAF dark green with a dry brushed lighter green that the pics really don't capture well, out of scale sprue antenna (but I like the look) and two red stars from the bin that fell apart after applying Sol, but managed to piece somewhat back together.

This is Too Cool! Any other Cool Projects Planned? Keep up the Superb Work Dan

Cool look!
I've always wondered how far backwards one of these vehicles would go when the main gun was fired? Assuming the vehicle does not dig into the dirt, it would make an interesting physics problem.
Assuming the vehicle weighs 50 tons or 45,360 kg, and that the 122mm gun fires a 25 kg shell at 800 meters/second, the vehicle would travel backwards from a stopped position at 0.44 meters/second or about one mile/hour.
(25 kg x 800 m/s)/45,360 kg = 0.44 m/s or approximately 1 mile/hour.

It may only travel an inch or so.

As the gun's axis is quite high it will exert a torque about the hoizontal axis of the tank and so tend to dig the skirt at the back into the ground. That should stop it moving too far.  

The gun-layers job would be a bit of a bitch as he'd have to re-lay the gun every shot if he wanted to stay on target, unless the tank had a gyro-stabilised mount like ships do of course.

Fantastic and a surprise. Reading the title I expected a "normal" JS3 but with a hovercrafts skirts instead of the tracks

WOW!!  I love this    What a cool idea !!

Perhaps add a spade like device on the rear to catch the ground and absorb the damage?

Can't.... stop.... grinning....

So cool

[Captain Canada]

Nice work ! Looks the part to me. I always hate how the camera 'steals' away details like that....need to hire a professional model photographer !

You know what would be supercool, and cat crazy ? Making one of these out of a Rumba vaccuum !

[TallEng]

A round tank! What ever next?
And there I was thinking JS3 hmm... Joint Strike???

Grand idea

No issue whatsoever......122mm railgun.

That's a BRILLIANT idea!

Now I have to look up RC model tanks with a gun that fires (or at least makes noise!). JS3 might be hard to find but I know there is M-1 Abrams out there.

[Geoff]

Oooohhhh! Yes!

I did exactly the same thing - nice one Scooter! 


On the subject of recoil, railguns don't have any less recoil than CPR (Chemically Propelled Round, i.e "normal") guns. The recoil is caused by the fact that you're throwing mass away from you, not by the mechanism you use. In a railgun, the round and the barrel are "connected" by the magnet field so the gun is pushed backwards in proportion to the force in just the same way as a CPR gun.

I suspect that if real hovertanks ever do come to pass, they'll use a combination of lasers (if that technology comes to pass too), missiles and small recoiless guns like the RMK 30: http://en.wikipedia.org/wiki/Rheinmetall_RMK30

What a great build.......
