ok, that is just a stupid response. if you know 'bout them, them by all means you may post it.

my fooking grandad is in the fooking hospital. i need to be there. somehow that has priority over posting 'bout turbines on RR. i will post it when i want to. i don't feel like typing that much anyways right now. i've too many other things to deal with.

lay off

Check out this thread. No typing? http://runryder.com/helicopter/t141800p1/

that's not a lot of typing. christ lay off you paraquat.

since you have seen so many of these turbines, you too can type all 'bout it.

i actually have got better things to do. i will see 'bout it later.

and figuring the problem is a safety issue. good god man.

Alistair, hmmm why don’t you just copy the pm you sent to that other guy?

As others have pointed out you have posted in other threads, plus in this one.

You say being by your grandads side has more priority than posting about “turbines on RR” why are you posting at all on RR if you need to be by his side?

I may be wrong but it really sounds like a lot of hot air……

I'm un-sub-ing from this thread. The turbo expert is now doing the Seneca thing, that is, if you can't participate in a debate with facts, call people names. Let me know when this guy re-writes the laws of physics. Good god, man, it's a safety thing!

the turbo is not a safety thing you idiot. my heli is.

i do not have time to type it. i'm sure you can find it in the magazines.

"the tubine is operated just like a real one.

a pipe runs off the exhaust manifold (you have to use his. no more giant tuned pipe... no bother... lol you don't need it. it's optimized for the engine/turbine power). that runs to the scroll (turbine inlet) which goes to the carb. there is a carb extension (your carb will be taller if you will... imagine your carb just sitting a bit higher 4-6cm i'd say or there abouts). and that's it the turbine is cooled/oiled from the fuel/oil mixture from the engine. it also comes with different jets to supply more fuel for the turbine as well as lubricant (oil).

he also makes a torque converter, so you can do away with that silly clutch system they've got.

.... lol also.... he makes better disc brakes for the front and rear.

and he makes frames with very nice suspension (well for a go-ped atleast) that is fully adjustable.

you can also request the frames to be powerder coated in any colour you fancy.

i am 99% sure he things come as "conversion kits"... that is, everything you will need to do it. so you won't have to jockey for strange parts, or one offs that you can't find if you kill it

you can also specify where you want the power... ie, higher, lower, mid etc to suit your riding style... or for racing it. be it on or off road."

he makes them upon request. i think he has also got them in a magazine, so people contact him through that.

i have another stupid question........ (i have an unlimited supply

)

an easy way to test the theory weather or not a turbo would work on a 2 stroke heli engine. how about getting a line of compressed air and fire it directly into the carb, and tack the before and after.

That way you wouldn't have to go through the expense of buying a mini turbo and retro-fitting it to your priceless engine and finding out it doesn't work. just mount an engine to a test stand and blow compressed air into it and see what happens. i would do it myself, it would be easy to take the engine out of my nexus (4 bolts!), but i dont think my air-brush compressor would be up to the challange....plus i dont have a tack.....assuming you would need one.

Furious, make sure you get a set of those disc brakes for the testing. They should keep the Nexxus from blasting through the wall. As I expected. Alistair knows little to nothing of what he is talking about. I've read his awesome explanation twice, still makes little sense. Alistair, do some research on turbines, as they are quite different from turbochargers.

Did he just call you a weed killer? I don't know SweetP! You know, you take one of those UK guys, you put them in a place with no VAT, and sunshine, and this is what you get! Go figure!

Alistair, you say it comes with different jets to supply fuel for the turbine?
so now the two stroke has turned into a gas turbine engine??

Why the heck would you use a torque converter in a scooter? you will need to add an oil pump, you will end up loosing power.
A centrifugal clutch works like a torque coverter anyway.

that was not the entire pm. just part of it.

you don't need any pump for the scooter. it's a self contaned unit. it works quit well. on the scooter where the engine stops when you stop. then it starts again when you go.... gets rid of that. runs 'till you shut it off. it's nice and smooth, and i believe you can adjust how hard/quickly it engages to suite you.

the two stroke is still a two stroke. in some cases the carb gets new jetting, in other cases it gets a different carb. it think that is determined by how much they want to spend and by him.

al al al. turbine is short for turbo charger. i know what they are. i've been playing with them my whole life.

you can also say the scroll, snail, or the fire-breather.

no fuel goes to the turbine. i think you're thinking of the other kind of turbine.

sunshine has got nothing to do with anything. i'm always like this. haven't you got something better to do than to read my post? i mean really. oh right, you do... you have to post in a thread i started... sorry, i forgot.

again al, you're an idiot. how could you not know i'm refering to a turbo charger when the first thing says.......

i do not know how exactly it would be set up on a heli, nor do i know exactly how effective it would be. we have not tried it on a heli yet.

he has just made them for r/c cars, trucks, boats, and scooters.

he has a heli, but most people ask 'bout a tubine to put on their car or boat, or go-ped.

i'd imagine that's why he hasn't made an effort with the heli engines.

So your saying the torque converter doesn’t need an oil pump?
dam your friend must be good, you can turbo a two stroke and make a torque converter run with no oil pressure.

And no turbine is not short for "turbo charger" turbo is short for it.

I have never heard anyone refer to a turbo charger as a turbine, but the more I think of it the better it sounds, I can now tell people my car has a "turbine" in it, I can imagine what the reactions will be.

it's oil filled. filled with ATF it's little, and it's orange.

he's crazy and he's an engineer. always metalling with things... lol

his turbo -kits- are pretty well done. may even have different port's/timing. i'm not sure.

tons of people say turbine mate.

i think it's funny when americans say yeah.... i want to get a TURBIN. so i say... so you're saying you want to wrap a towel up, and put it under the bonnet. they usually don't get it

a turbo charger is still a turbine. just not a jet turbine.

Al,

Just to add my two cents worth. You CAN turbocharge a piston ported 2-stroke engine. BUT you are REALLY limited on how much boost you can generate. Why? A turbo does two things: 1) it compresses the intake air. 2) It causes back pressure against the engine (if it didn't have back pressure, it wouldn't turn). Because you are pumping the intake charge against a high pressure exhaust, you can get some boost and some power increase out of a turboed piston ported 2-stroke. But LORD! It will suck fuel like NOTHING you have ever seen before.

My main "yeah right" point of this whole model engine turbocharger is based purely from a fluid dynamics point of view. As small as these turbochargers would have to be to fit on a model helicopter (even a gasser or 90 bird), the cleances would have to be so tight to get any kind of efficency that it would be impossible to make one that actually made MORE power than what you started with. And even if you could, it would be more money than most people have tied up in their car. Heck, even the automoble turbo chargers are fairly low on the efficency scale due to their small size. And someone wants to make one about 1/10 the size??? That means about 1/100 the clearances to keep the efficencies up. I don't see it happening, but I would be very pleasantly surprized if someone did.

Now, before I say "yup, I was wrong and you CAN successfully turbo a model heli" I would need to see a few things; 1) Before dyno test of the engine. 2) After dyno test of the engine. 3) A video of each dyno run so I have some confidence that it is real and not a pile of BS edited together by some 14 year old.
