I genuinely don't mean any irony in the question. But I've read several threads where people raved about the handling and performance of these helicopters but weren't very specific about why they liked them so much. Is it their power to weight ratio? But on youtube most of the turbine helicopters are scale rather than pulling 3d stunts. Or are they bigger than other helicopters? But why can't someone just build a larger IC helicopter?..

Hence my question. I've never actually seen one in the flesh.

the smell and sound, and the satisfaction of putting in proper jet fuel. it is the ferari of the Model hellie world.

I also like it for scaring planks away, even more so if you get a wet start.

it sounds so real, and is the closest i will get to the real thing for a long time.

Sound, smell, reliability...

... and the fact you can fly a pretty large machine with very little vibration and tonnes of power reserve

Those do it for me

Because it's the closest we can get to the full scale machines (I saw a big Lama in flight - 3 meter diameter rotor - it was really hard to tell if it's a model or the real machine).

My turbine EC135 looks & sounds pretty real in flight as well

What's so good about turbine helicopters?

Where are you in the UK, there are still a couple of events where you could see and smell a model turbine
As to your question, when you get one, you will know you have not made a mistake

I have to agree with peter once you have one you will never regret it im so glad i made the right choice to go into turbines cant wait to get mine setup in the scale fus im building

As a poor student, it might be a while before I can get one. But I'll try to get to see one at least.

A few more questions...

I presume they're mostly 7-20kg?

And is the reason people don't seem to do aerobatics with them primarily because of the price tag? Otherwise what's the point of having all that excess power? Why not use a smaller turbine?

Mine is a Trex 450. Very much the other end of the scale!

I could not agree more. They are the ultimate engine for a scale heli. The perfect engine, IMHO.

For true 3D, they don't touch a hot 90 or well done electric setup, but maybe someday they will.

I think Wren is in the works of producing a smaller turbine just for less overall mass, don't know when it is due to be released but I want to say it will be MK44 I think. You would have to check with sara at wren for more info.

hmmmmm... oh, and that

reciprocating engine mass that cannot be balanced...

like a proper electric, vibration free...

everything lasts longer....

Why not use a smaller turbine?
Turbines are much much more difficult to miniaturise successfully than reciprocating engines. Already tight acceptable tolerances decrease dramatically for smaller engines, quickly to the point where the machining becomes very difficult indeed and there is high wastage. Accuracy of assembly also becomes far more critical as a result of these tolerances. The end result is that making smaller and smaller engines results in rapidly spiralling production costs, contrary to what you might expect

Because they are cool to the MAX and give me a CHUB. If it were easy or cheap everyone would do it.

Easy; the smell, the sound, the complexity and the fact that it`s possible to make a miniature turbine that works.

For me it`s also the ultimate thrill to fly. Not because it`s difficult, but because it makes more fun than all of my other helis - and of course it`s cool to own a personal turbine. Sorry two

I have been fiddling with mine all day today, and nothing beats the feeling of this machine. It`s big, it`s complex and it is just plain awesome. But it is also another aspect that thrills me, and that is this place at RunRyder, where you encounter nothing but friendlyness and good advice from interested and extremely knowledable people.

I am going flying my turbine tomorrow, have to go and set everything up

Tried planks, but after all, wood is best on the bonfire.

i agree that turbines seem to suit scale applications better but i have seen bob johnson 3D a turbine heli think it might have been a wren and what i could see it was as good as any other heli not that i can do 3D just what i saw,but then if you can fly like bob turbine or nitro most likely dont matter

I have also seen Greg Alderman 3D the Bergen / Wren quite well. Takes a lot more nads than I have.

Bob Johnston's Cuatro started off with an SPS turbine and then changed to a JetCat SPH5 I think, using the SPS Cuatro conversion. A very impressive and minimalist turbine heli!

Whatever the powerplant though, Bob really did throw that machine around very accurate smooth routines. That also has to be one of the fastest helis in a straight line I have seen - it was way faster than my Cuatro gasser!

Bob Johnson started with a SPS Turbine, which was a Wren made by our (then) colleague Simon Peckham. When Simon sold himself to JetCat - taking the Wren designs with him - Bob tried the early SPH helicopter in 2004 but had problems with it. He discovered who the original designers of the two-stage helicopters were and has been flying a WREN Cuatro for two years now.

so what you are saying then is Jetcat is a fraud and were desinged on the Wren.

Sorry that maybe the case, but what Jetcat has done is improved and moved with the times.

I think it is unfair to bash it especially as a manufacterer.

Cos i think if you did a poll on here there are loads more Jetcat onwers than wren. from reading a thread on the predator wren, there is only around 4 people on here regualry that have one, it is is,ilar qtys with the quatro.

I am not going to debate the wren v jetcat, but all i will say is there are alot more helies with jetcats in than there are wren, and that says something.
