Gun Barrel Recoil

[Jim Fowler]

Well, since we are weighing in... I don't like blanks. seen one fellow blow the lid of his tank loose once; and the mess of having to clean it (I think the lack of latter is what caused the former..) But, I also don't like the "buck for the band!" either.

Overall, I like simulate fire because of the recoil movement, and I have to also say the "sound byte" style roar seems to lend itself more to the scale effect over the "pop" of a blank.....IMHO.

Were the animate fire-effect falls short is in flash and smoke. But, I think as we explore the possibilities and ideas in those areas, they will come too.

Well, that is my thoughts on it,

Best Wishes,

Jim

Hello, as a newcomer, I would like the recoil and smoke. I have been completely enthused by the Benedini main gun sound...with...echo....echoooo.

I had a 1/16 Tamiya Tiger which as you guys know, recoiled and 'sat back' on it's tracks....very realistic.

That's my twopenny worth...Mick.

I would just like to just add to my initial comments on this subject that I think we can all agree that Armortek make the best 1/6 scale tanks in the world, these kits represent a significant financial investment to us all. One only has to read the forum posts to see that realism is a matter of pride and necessity to all who post here. It is therefore such a shame that these great beasts don't currently benefit from the awesome sight of main gun recoil. This to me would be the icing on the cake when proudly showing off my Tiger and Panther and truely enhance the experience.

I’m sure that Mark and Gill have invested considerable time and money into the development of the blank firing system and it’s easy for me to sit here and hope that they would drop this current option in favour of a recoil system when it’s not my business or money at stake. But there are an awful lot of kits out there now and I would think that there is a fortune to be made from offering a recoil upgrade in much the same way that the double torsion bar suspension kit has been offered to the first batch of Panther owners. I would be first in line for 2 kits myself!
Everyone is going to have there own opinion about this but I just can’t help but feel that the realistic recoil and sound of the main gun, particularly if smoke discharge could be added, would be so much better than the unrealistic crack of a blank firer (Whilst Mark & Gill have developed a great system it can never truly simulate the sound & sight of the 88mm firing).

This is all just my humble opinion, and should be taken as such. I’m sure there are plenty of you guys that love the sound of the blank firer out there.

Anyway, I’m sure that time and market forces will dictate where the future lies

Keep your thoughts comming!

Hi guys.
I'm all for the Gun realism aswell and there have been a few
recoil systems shown on this topic and elsewhere.
I've done the flash in my Comet barrel with Halogen and Dennis
has used Xenon following Jim Fowler's article.
With the smoke I have been trying the Piezo and Armortek's
standard smoker.
The oil based one was the better but only because you could let
the elements heat up a clump of smoke then shoot the lot up.
I dont know how long the elements would cope with out the fan
for periods though.
Getting the smoke past the wires and the Halogen or Xenon needs
looking at.
Armortek's new smoker upgrade has rekindled my inthusiasm,so
I will be in the que for one,so I can blast it up my pipe.
The movement and timing of the recoil is not a problem for me,I
am going to permanently borrow the idea of the Linkage from
Adrians Sherman vidio and the using of a Turnigy from Robin's
set up.
I've already tested that and its great,the servo power is no
problem with the 24kg jobs,and the Turnigy is fully adjustable
for slowing the runout after the recoil
The only bit I'm stuck for is the barrel to run in a bearing
because I dont have any turning or boring machinery.
So if the Armortek barrels were sliding in a nice bronze bush,
the equipment and ideas are already there and the blank firer
enthusiasts would just have to have the barrel fixed for safety.
I dont think the recoil upgrade would be as easy for Mark as the
exhaust fan,because of all the different Guns and parts,but its
possible.
Going back to Smoke coming out the Gun,I think this topic alone
will have as many opinions as the exhaust smoke.
I've watched quite a few of the vidios of Tank firing via Phils Links
and the smoke differs greatly from Tank to Tank,with gun design
and the charge are 2 that stand out for me.
Does any one know of a vidio showing the Comet firing so I can
see what to aim for
The rocking back on the chassis would have to involve the
amplifier module I think to stop the engine sound,like Tammya do.
I might have an experiment with my radio to see if the amplifier
can be fooled into delaying the engine reversing sound,perhaps
with the use of the exponential faccillity.
Hope these ideas have helped.
The difficult I will have a go at tonight,the impossible I will have a
go at tomorrow
Cheers
Phil

Hi Guys

If your thinking of a powerful servo try the link below, I have these for Fin's jeep, 200lb torq a great bit of kit

WOW thats a powfull servo Richie.
That will even get my son's wallet out of his pocket

There's also the problem that the Panzer III doesn't even have a hollow barrel, though I think that is the only model with this issue.

> Does any one know of a vidio showing the Comet firing so I can

It should be pretty similar to a Sherman Firefly, I would have thought ?

> The rocking back on the chassis would have to involve the

I wonder if it would be possible to use a second feed directly to the motors, rather than involving the amp and speed controller ?

Can Mark confirm whether this would risk the output stage of the speed controller module ?

Adrian.

Hi Adrian
Do you know of any vidio clips of the Fire Fly Gun firing?
I had a quick play last night after doing that posting,and discovered that
my Comet left hand track will reverse a couple of inches befor the
motor kicks in,but on my right track the motor sound is fairly instant.
My channels 3 and 2 all have the end points at 100% each way and trims
are at zero.
I will have to see what effect it has when my Comet is ready for the
ground.
will have to see if my Panzer is the same and look at the effect.
Cheers

Hi Phil,

There's a couple of frames of Firefly's firing in the video below. The first one is around 1 minute in but it's a very interesting video anyway.

Thanks Ant

Thanks Ant
A good little vidio on that Link

Well, I guess we all need to look at Mark and Gill's latest (T-34). Seems Armortek is going to incorporate a recoil and flash in that model - let's all keep an eye on this.

AND, I want to say thanks to Mark and Gill for listening and making this available in the new model!

[Adrian Harris]

Here's a link to a video of the recoil system in the prototype Sherman, which I have managed to get linked up to an Armortek Amplifier Module so that the recoil now operates in sync with the main gun:



Depending upon the length of the "Honey do" list, I hope to get the Panzer III trialled with this system as well, though I'll need to make a different adaptor for the end of the barrel.

Adrian.

Hi Adrian,

I watch your recoil video on you-tube,
nice job that recoil connect to the sound module,
is that a lot of research to come to this?
I wanna make also a recoil for my king tiger instead of the blankfire.

Hello Adrian,

Nice video. Is it possible to look "inside" your project. Hope one day to fit a recoil in the Panther.

[Adrian Harris]

> is that a lot of research to come to this?

I already had the recoil system working with a PIC microcontroller, to produce the different forward and backwards speeds of the barrel. Configuring it to trigger on the signal from Thomas's unit was quite straightforward, once I had tuned the settings to the new Futaba servo I am testing, which has quite a different range of movement to the prevous Sankyo one.

> Is it possible to look "inside" your project.

I hope to have a functioning Panzer III system shortly, with muzzle flash as well, so II will unveil the complete system then

Adrian.
