JJC turbocat or Large ships diesels if you can get one. They are the best.

I have just brought an ACtion one, can be set for 4, 8 or 12 cylinder. Sounds good to me.

JJC seem to have sunk without trace, their voicemail box is full and nobody seems to stock the sound simulators any more. As they (to the best of my knowledge) are the only manufacturer to produce a unit with the engine starting up at the begining I don't want to buy any other type until I know JJc are no longer producing sound units. Can anybody help?

Contact Dave or Liz at ACTion. I've bought some goodies off them recently and been well impressed with the service. Havent used the diesel sound unit though.

The JJC sound module runs off the main battery 6v and upwards, what are the limits on the ACTion ones anyone know ?

FLJ as you will be the first to point out my knowledge of any sort of electronics is limited to what I have already carried out. So as I have never fitted one of your engine sound units, could you tell me, as I have no seperate receiver batteries and just run off the main battery, will your unit work in my boats ?

I too am looking for a couple of sound simulators, I had 2 JJC ones that sounded terrific, but unfortunately where faulty, anybody got a video of the action sound systems?
Thanks

Guys
The bottom line is that if you're used to the JJC sound system then you'll probably be a bit disappointed with the ACTion one. Allow me to try to put the thing into perspective (any lapses into techno-babble will be strictly minimal!).
Jim's units are based around actual recordings of diesel engines which are held in digital form and reproduced through an amplifier. Moving the Tx throttle stick will modulate the recording to sound like the revs are increasing and decreasing. It's quite loud and very expensive. It will also operate from any ESC.
Craig Talbot designed the original P15 ACTion Diesel sound to be run from an ACTion ESC - quite naturally. It, too, changes revs with the throttle stick and it will run using any other ESC which uses a relay to reverse the motor e.g. the older Electronize one, but you can forget using a Viper or Proteam etc. Latterly he introduced a PIC-based diesel sound which avoids that problem by taking its signal from the Rx, not the ESC. This means it will run on most if not all ESCs.
Limitation No 2 is that the sound isn't a recording of a diesel engine; rather it's just a series of generated clicks which are modulated and filtered to sound a bit like a diesel. If you're after a start-up routine and the whistle of a turbo-charger then forget it, although you can adjust it to sound like either a 4, 8, 12 or 16 cylinder engine and also adjust what Craig called the "character" (i.e. the lumpiness"). There is also a version which reproduces the single cylinder pop-pop of a small workboat or canal narrowboat.
Limitation No 3 is that it was designed for small models so it's not very loud, The little on-board TDA7052 amplifier is rated only at a maximum of 1W on 6v into an 8 Ohm speaker, so if you run it constantly on full volume the amp chip gets VERY hot (they've even been known to crack). There's not enough room in the case for an adequate heat-sink to dissipate the power at this level. We are working on a 6W booster mixer/amp but it's early days yet.
Not that it's terribly relevant, but just before he died Craig was working on a Robbe truck kit. This was a wondrous beast with working lights, fifth wheel, hydraulic rams.........and a diesel sound sim. This had the key-start-up routine and a glorious bass burble. When I asked him if it was an ACTion unit he gave me a very old-fashioned look.........!
To sum up, if you're happy to have the engine sound more "character" than "actual", and you don't need it to be any more than background (like the real things) then you'll be happy with our units. If you're after a cut-price JJC job then forget it............and, no; we're not going to develop one either!!
Richard - you're more than welcome to try one and return it if you're not happy. Contact details are on the website or PM me here.

If you phone around some of the JJC stockists you can still pick up sound units.

I have just got two diesel sound units from Scoonies and i think Westbourne may have some others.

Hope this helps

Hi all.
I am in the process of developing NEW sound units. They will be similar to the JJC.

The more feedback I get the quicker they will be developed.

PLEASE let me know what YOU want in the sound units. I have already made improvements both to the robustness and sound quality.

Realistic Steam engine. Large & Small.
Modern Diesel Large, small , fast.
Random Naval sounds - single unit.(whoop, whoop, Klaxon, Lines from films ie. "All hands to stations!", "Mr Bligh, report to the ward room." etc, etc. )
Random Battleship sounds - gunfire etc.
Random Merchant ship sounds - single unit. (engine, horn, winches, seagulls, deck hands shouting, metal, hawsers scraping decks etc.)
Random Pleasure craft sounds - single unit. Seaside, harbour clamour, seagulls, 'I do like to be beside the seaside', children playing.

Must be loud.
Must be realistic.  O0

If you make them as realistic and as easy to fit as the JJC units they will be great.

Expensive crunching sound triggered by proximity detectors whenever other boats approach too close or you hit the bank agaim.

1) German national anthem for u-boats entering port.

2) Loudly shouted german orders for alarm, dive, schnell, achtung, etc.. etc...

3) German music that may be heard coming from a u-boat on patrol as they pick up home stations.

seriously... start up cranking, proportional throttle, LOUD!! light, waterproof.
Anthony, we have mailed each other, I want MTB sound and fast v8, just like the jjc units. I think we would all agree that if it wasnt for the disappearance and therefore poor service of JJC we would all be using his kit, so if you can replicate JJC you are on to a winner, BUT.... not too expensive, and a web site where we can hear samples please!, and a guaranteed back up service

Hi all.
I am making progress.
I will be needing SOUNDS soon.

Any recordings VERY WELCOME.

Thanks
