Armortek

They say it's 1/6 scale but would it fit in a Tiger I, Panther or King Tiger type? 5HP, water cooled and sound/smoke is free.

I have a transmission that can handle 5HP....

Jerry,

That would be something to put that into a Tiger I. If there is someone who can do it - it has to be you!

Good Luck,

Dan

That is way too cool!!

Thanks for sharing (I think, Buy button is where, how much)

I'd love to have the engineering skills to drop one of those into a Tiger. Perhaps adapting a gearbox from another r/c model would do the trick.

I appreciate the confidence in my poor abilities being able to adapt one of these for one of the tanks!

Looking at the raw dimensions of the engine I believe it could be done however not certain of the life expectancy of the thing. What would the practicality of running possibly a high-strung V12 48 valve engine in a tank be. While I like the idea and I've actually decided to try to get one, they're only offering 50 of them, I doubt it will be anything other than a novelty sitting in my mini-museum/house.

Some of you know that I spent the first part of my tank modelling 'career' working with ICE (glow and ignition) powered models so some of the challenges are familiar to me. Unlike the higher revving engines I'm used to this V12 according to specs has a top rpm of 12,000rpm. With that in mind it's not too difficult to imagine a transmission and final drive that would result in the requisite sprocket output shaft rpm range of ~0-350 rpm (for a larger WWII vehicle). I'm very familiar with a simple braked differential transmission design and have already built one for one of my 1/10 scale models so building a larger version wouldn't be much of a stretch; that or perhaps a dual/controlled-differential type that would be slightly more efficient- beyond that and it's a much larger project.

It boils down to one's eyes being larger than their skills and time. I'm a very slow builder. I have 50 tanks/ tank projects in 1/10 scale and as Monique or Kian could attest I've built up quite the backlog of Armortek kits to be built so selecting one for a V12 engine wouldn't be too difficult.

Thing is based on the works of folks like Liam and Paul I've become quite impressed with the capabilities of BLDC motors, the power available is nothing short of miraculous. I never thought I'd say it but my focus is there, even though I'm still not entirely keen on the fact that I can't just plug a motor into a battery to test it, I like the power. I plan to gear my models much lower and slower than most of you; I like them that way.

"Slow and majestic."

So yes I like this v12, I hope to get one but I doubt very seriously it will ever see the inside of a tank... but it does tantalize the senses doesn't it!

Jerry

Good Luck with that beast!

Found a sales link.

I must admit Tim I'm vacillating. I have an order in however I'm considering cancelling. I really enjoy the oddball or offbeat aspect of this but on a practical note even if this or similar engines proved to be usable and performed well what would maintenance be like and would there be spares available for bits that would very likely wear out? It's inevitable with complex mechanisms.

It's a good thing to replicate the characteristics of a Tiger say in detail and form but not so much to replicate the engine shortcomings as well. I have to think these things through these days. I've read of other fellows who have either built their own or adapted a multi cylinder engine to a 1/6 scale model and it has most often led to disappointment and or maintenance woes, even hard failures.

Most of my 1/10 scale ICE powered models revolve around 1 engine type; the venerable Webra 6,5ccm (.40cid) "Blackhead' in 'Stamo' form introduced in the early 1970s, now out of production (MECOA owns the brand). The thing was nearly indestructible and usually produced about 560 joules (.75hp) at it's top end. A ringed engine with a steel cylinder liner some of my oldest are 48 years old and still run well, perhaps needing a new ring; and that's after years of running. I have so many spare engines, new and old as well as parts I could keep them running for another 60-70 years..... I doubt this V12 would get anything even remotely like that longevity but again it's several orders of magnitude more complex.

So... ? who knows....will I... won't I....

Jerry

What an impressive engine! Impressive the way it's made, packaged and shipped. It doesn't hurt that I'm on the West coast but 2 days to get here from Hong Kong. Packaged as impressively and securely aas anything I've ever seen. N ow if it will run as impressively as it appears, but it's almost too pretty to run!

I was pleased to discover that the engine has steel cylinder liners and 3(!) rings per piston...

Here's a few images. No doubt it would fit in the larger Armortek models length and width wise however height would be a challenge. The
engine comes without the water pump installed.

I doubt I'll actually install the engine anywhere but it's so cool to look at!

Jerry

And you built it that fast.

I've been looking at the Cison 1/6 scale V-8 a lot.

PM if you have any thoughts on it. Good or Bad

Thanks

Nice Engine.
I thought about to put it into a AC Cobra (V8).
BUT:
-Unfortunatly in Germany you can't drive it at all places.
-It is verry loud and the sound is not realy like a V8,V12
-last but important. The torque will be never enough to get the Tiger move. Maybe you have enough HP, but less torque.

Clever gearing is needed. My smaller scale models only have the aforementioned .75bhp but can move a 75-100 lb (34-45kg)
model very well. Yes the engine is running at high revolutions but gearing is key.

The point about gearing is interesting. These small ic motors have been around in different configurations for many years and I've been tempted myself but always thought that there would be insufficient torque to move a heavy tank as florian mentioned. I wonder though if a multi cylinder ic engine has to run at high revs continually how long it would actually last. Go on Jerry have a go!

Knowing that torque is related to power torque = hp/ (rpm/5252)

and that the power to weight ratios of our models is far greater than the original machines it explains why a small motor or engine
when properly geared can move a relatively heavy model, seemingly very easily.

I'd be happy to share my calculations offline with anyone interested but I feel from a purely numerical perspective it is very doable.

Longevity is a question that I've puzzled over. I know how well my small 2 cycle engines have held up over the years of running however
how one of these small very complex and possibly fragile engines would hold up? Who can say. Being a tank engine is not a very hospitable
environment. I've always taken great pains to maintain my engines and I'm very guarded as to where I run my models in part for that consideration.

Jerry

Due to this thread, I now have a Cison V8 paid for and being shipped. I'm on the other coast so might take a few days.

You did a great job of putting that engine together.

Way to go.

I still think we can get them in a tank. LOL

Later Tim

Tim, the V12 I purchased was a built engine; not even certain if it's available as a kit. I don't want to have credit (or blame!)
for something I didn't build.

Congrats on your acquisition.

I thought about a kit for the other engines but I have a built-in lazyometer that warns me of impending work...

One bit that's making me think implementation is clutching between engine and transmission. My existing systems use a centrifugal
clutch (think RC choppers) which is quite effective for small, fractional hp engines however I don't believe they'd be as effective here.

The steering part is relatively easy; a braked differential on the final drives and Bob's your uncle, simple although not terribly efficient but very effective.... it's the in-between rubbish that's in question.
