Main gun recoil

Is there anyway to link a servo recoil system to the Benedini main gun firing sound, what i am hoping to get is the gun to recoil when the sound is triggered.
Thanks
Steve

Hi, Steve

The MG's in turrent and front had no recoil system , this system only had the 88 mm Gun.

For a quick for-and reward look at the Wheelsystem at a Steam railroad engine. Here you have a high-speed Wheel turn ( electric motor ) , and a quick goeing for-reward push rod.

Iam not sure that this the right words to explain what I mean....
I think of using about this system after around it for the 88er Gun to recoil them complete with the Armortek blank firer .But I still wait for the right idea to realise it technically . :?

Steve,

I rigged the recoil to trigger the sound; but the other could be done.

Go to :
http://home.comcast.net/~chioc/rctankhobby_1208_002.htm

The recoil control they sell will actually control even a largescale servo - with a bit of extra wiring.

Feel free to email me if you need to.

Hi Steve,

You can combine a servo operated recoil function with the Benedini soundunit through the optional digital input unit.
More info is available here http://www.benedini.de/Home_E/Products_E/TBS5_E.pdf (page 3)
or by an e-mail to Thomas of course..

I have been working on an electronic main gun fire mechanism and control system. I developed an article in PDF format covering the control system. If you are interested it can be viewed and downloaded at:

This article may also be of use to those using a Benedini sound system, especially if in Digital Mode.

I would like to thank Jim for all the effort and thought he has put in to produce a recoil system that can be used on most large scale tanks.

Well done

Steve

Hi Jim,

A big "thank you" from me too.
Great piece of research and construction.

Excellent work on this Jim!

It's very good to have a post on this subject with such a great write up and thought put into it.

As others have already said, Thank you for taking the time to do it and put it together in an understandable format for electronic know-nothings like myself. :oops:

Kind regards
Tim

Tim and everyone, thanks for the kind word, I am glad to be able to contribute.

Jim,

My colleague Howard has designed a mechanism similar to yours but controlled by a PICAXE chip which gives the fast recoil and the slow return which is quite neat. Have you ever dabbled with these things? They take a bit of understanding but when you've grasped it they are very flexible little devices!

Thomas designed a little circuit for me which basically plugs into the TBS5 sound module and allows either LED gun flash (MG or main gun) to trigger a small relay. I use these to power small Puppet/Wizard boards to, for instance, move an MG in synch with the LED flash from the TBS5. Something like this could be used to trigger your mechanism maybe?

Stuart,

I have not developed anything to control recoil/return speeds as Thomas stated this was something he was looking at as a future offering. Also, Nick at TankHobby was looking at as well.

I am working on a follow-up article on making the machinegun flash in sync using Digital Mode as I need/want it for my Panzer III.
I hope to have it done between Thanksgiving and Christmas this year - if work allows.

But, I am trying to make it from something simple as I work a lot on the KISS philosophy. I am looking to usecommon or readily available parts - like TankHobby Recoil board.- it was available, cheap, and it works.

I think if people show and interest in using an electronic fire control system, someone - and someone better than me - will most likely offer one. Imagine, recoil with speed and travle control; with an on-board BEC; made specifically for a large scale servo; and lets through in something for the machinegun to - somebody make it and make it cost-effectively.....I WOULD BUY IT and replace what I got!

My efforts are not to be the manufacturer as much as to be a lobbiest for the development of the technology. My article shows what I did with what I had on hand now .....and generated your response showing some of what could be. I think even if that is all it ever does, it was worth the effort.

There is another side of my putting out the article that I think I need to confess to everyone..... I see folks post stuff here all the time and I take notes, save pictures and just general "steal/take" it all away to use in my efforts. I really just want to be able to say I "gave" something back..... achieve some sort of "balance".

So, please don't think of me as an electronics guru or a great craftman...I'm just another average "Joe" (Jim) in our hobby who made the effort to give a little back.

.......And, the next time you see one of my annoying posts....remember I shared :wink:

Guys,

Steve Norris has found a flaw in my supplemental diagram on using the TBS5 in Encoder Mode. I will update it after I confer with Steve and get him up. - SORRY

But, the good news is all the info on using the TBS5 in Digital Mode (the actual focus of my article on electronic recoil) is correct.

I sort of threw the info on the Encoder Mode operation in as an after-thought.....well, I made a minor "fub"

I will correct and post again when tested, verified and update on the RC1PANZER site.

Again, my appologies.

Jim,

Share and share alike is my philosophy! That's what the hobby's all about, no point in re-inventing the wheel :D Good luck and keep us posted on how you get on.
