Simulate the shudder of the tank when firing

[Helderluiss]

Hi everyone

Can anyone tell me if there is any way with the electronics provided by Armorteck to make the tank's motors recoil a little when firing, like a hiccup, to give that shuddering effect on the model?

[Adrian Harris]

It's been discussed before and the consensus was that it would put a huge strain on the drive train for very little effect.

The suspensions on most models are too stiff to rock much when accelerating or decelerating, so I doubt you would get enough movement for it to be worthwhile. Plus there may be exponential curves built into the speed controller programming which would dampen any sudden inputs from the receiver.

As far as I'm aware, when a tank fires it doesn't actually move. The hull rocks on the suspension, but it doesn't move backwards.

If you simulate the rocking motion by jerking the tank backwards, the front will tend to dip down, not up.
If you simulate the rocking motion by jerking the tank forwards, the front will dip up but the tank will have moved forwards, which is counter intuitive for something that just fired a projectile forwards.

Having said all that, it's your model, so give it a go and see what you can make it do

If you have a TX running OpenTX or EdgeTX, you ought to be able to write a LUA script which provided a full speed pulse to both tracks for half a second or so, which should be enough to get the tank to move.

I am not an electronic expert, but a full speed impulse will stress the electronics and runs a remarkable amout auf amps through the controller and the motors. With the weight our tanks have, I am concerned that it will kill the electronic and/or the engines over time.

I know this "shoot movment" from the Heng Long 1/16 tanks, it looks cool, but it does not reflect the reality.

Here in this Leopard 2 video you can see, the tank is not moving at all during fire: [/media]

Another example for an Tiger I:


and for the Japdpanther:

I agree with the first, the other two are firing blanks/pyrotechnics, so there is no recoil due to Newton's third law of motion.

Lots of WW2 footage here and very little visible movement.

Whenever I saw one of the 1/16 scale tanks wiggling to simulate the main gun firing it clarified my
view that I never, ever want any tank model of mine to do that. It looked ridiculous.

But as Adrian said, it IS your model...

Hi Jerry,

full agreement by me. No real main battle tank moves really backwards when firing; only 1/16 - scale toys make that.

In the German Heng Long for 1/16 scale forum some comrades bother about removing this ridiculous behaviour from their tanks....
