Thanks for the comments guys.
Unfortunately, earning a living has got in the way of modelling over the last week or so , as I am very busy with work
But have got the battle system up and running.
Will turn my attention to the sound system when I get the time, I am waiting on a couple of small, but good quality speakers from RCtank.de

Hi all,
I've been working on the "sound system" over the weekend so I can play songs and sound files from the Kelly's Heroes movie. This will probably seem a bit crude to all you guys that have Elmod Blasters, but here goes.
My MP3 player is called the Kube, for obvious reasons, but my reason for using it is its 25mm cube size.

It stores MP3 files on a micro SD card, but only has earphone output, and tests in the past have shown that it needs amplification and a higher wattage speaker to make itself heard.
The idea is that at the start of a "session", I turn it on and pause it, then use a servo to remotely operate the play/pause button, using the rotary knob on my Futaba 7C
I used a combination of amplifier and potentiometer from Maplin again,looking for something that would fit into the ever decreasing space at the rear of the lower hull.

As I didn't want to connect this into the Tamiya speaker for fear of damaging the MF unit, I had to find speakers small enough so I could use two, one for each system.
These came from rcTank-de and are 15W units measuring only 50mm square by 30mm deep.

I started by making a holder for the Kube from pvc sheet, and fixed into place along with the servo


Once wired up, the amp unit just sits on the floor of the lower hull.

As the amp needs a power supply, I connected to the battery and used a small double pole rocker switch to Isolate when not in use.

I fixed the speakers on the upper hull, below the engine intake grille and used Deans connectors for easier removal of the upper hull.

Finally, to hide it all, I fixed black speaker cloth to the underside of the engine grille.

I will try to make a little video over the next few days.
Next mission is to find something to make the Loudspeaker from, I've been looking in cake decoration shops for a wedding bell, but havn't found one the right size yet.

well sparks if your gonna bake a cake you might as well put icing on it and a cherry on top but wedding bells??? I know the old fashioned PA speaker horn on the turret side,I watched your build for sometime now,and wondered if you were going for the music,glad you've lived up to my expectations,for speaker I suggest a Woofer! Woof! Woof! Trying to think of bell shape things for you,how deep and what diameter,I got some christmas stuff,say we cut loose man,positive waves!keep on keeping on great stuff sparks,hey when you finished there,fancy helping me rob a bank?

Thanks man, your positive waves re the Christmas bells have reminded me we used to have a set of varying sizes the played Xmas songs, I'll try to find them and see if one is suitable. I guess for it to look right, I'm looking for a bell shape thats about 25mm diameter at the largest point.

my christmas bells are 25-30mm chrome plated plastic,I suppose you can can cut them back if too wide,and you're gonna reshape anyway, so if you get stuck,pm me and I will sort a couple of em out for you

Thanks,
Man, with all those positive waves, we can't fail.
Woof, woof, woof,

my dog impression is more like this ruff!ruff!ruff! Owooooo!

man, this is just better everytime I see it! I have been waiting for you to get this tank done and see it is action! AWESOME BUILD!!!

Cracking build Alan, boy am I looking forward too having a battle with your sherman against my panzer IV, .......hopefully we will catch you at one of the battles later in the year,.........
Fleshy.....................................

Thanks for you very kind comments guys
As promised, here is my little tribute video to Kelly's Heroes.
Sorry for the poor quality, and appologies for the dodgy railway tunnel scenery.
For anyone who has not been following this build, all sounds come from within the tank.
I have shortened the sound clips so the video isn't too long (and boring)
