turbine

The major benifit of the turbine is the smoothness in which it runs, if you go touch the heli while the engine is running, you can't even tell it is running. glow fuel sends a vibration though the heli. For camera use it would be great and extremely constant head speed. The only real negaive other than the cost I see is that you need a 50 gallon drum to fly.

There is big horsepower in those jets... Coming up on 10HP this year. The power, the sound and the smooth engine could be interesting. I am not sure the turbine with its high rpm would handle the hard 3d very well.

Volkul,
You work on big jets (don't you ), do you think these little turbines could handle a good dose of hard 3D without eating themselves alive from gyroscopic forces?

Smiler, sounds perfect! Maybe I can get one on the household budget: 'mobile heater'. Wouldn't be able to fly in the winter, though, it might melt a hole through the 'field'.

I'd love a turbine, but I can't even afford to dream of one.

Vokul - There's only one advantage.....the sound....

Scott - Nope, not becasuse it would eat itself but because the throttle response isn't too great with a turbine, not as fast as what a piston engine will do anyway, so don't think it would handle the hard 3D too well.

This sounds like the post of a man who who knows he will never be able to afford one
Peter Wales,

Not that it's any of your business but that can't be further from the truth. I know VERY well what a Turbine powered machine can do and I know Very well how useful they can be. I just can't see much for turbines in these helis. No need to attack some one. If you want to attack some one you might want to know exactly whom you are attacking.

This is what I work on for a living so I might just have some understanding of these things. As a matter of fact the jets in these pictures are ones I have labored over many a day. So Peter, before you spout off about things you know very little about I suggest you get your facts straight.


TO all others,

You see this is MY pespective of things. I play with 30 Million dollar toys everyday. So another turbine powered gadget is just that. I guess I am jaded by it all. Sorry for the rant, Peter's comment really pissed me off.

If Li-Poly technology is anything near what it is hyped to be we'll all probably be flying electric in a few years. Those brushless motors sound a lot like a turbine.

Well I am very sorry for pissing you off Mr Volkul Sir. Perhaps if you didn't go around making stupid statements like turbines should only be for plankers, you wouldn't piss other people off. The only reason anyone, who previously had seemed quite sensible, would make such an inane statement, seemed to me to be that they couldn't afford it. So I said, it SOUNDS like the statement of a man who couldn't afford one.

I have no idea whether you can afford one or not, and frankly I couldn't care less. It looks like you can afford one with having some of those fighter jets in your garage, but I have a sneaking suspicion they may not actually belong to you.

You play with your turbines and I'll play with mine, and I guarantee you I will have more fun than you.

I think turbines in Scale apps are here to stay. The sound made coupled with the scale look is just breath taking. When I joined the hobby, I was sorta dissapointed that they didn't sound more 'real', but seeing turbine scale apps have renewed my hopes. If I had some money to kick around my dream would be to build a scale airwolf or Bell222. Freaking awesome!! Dave Storey flew a scale turbine airwolf at our field. He flew it at dusk and when he spooled up, out of the top functional jet ducts, came this blueish white streaked flames. Looked like afterburner on a jet. Then once the heli was spooled up, the flames stopped and a red glow was emmited through the exhaust ducts. Then he would pick it up and hover and I've never seen a helicopter sooooo smoooottthhhh!!!! Couple with the looks and sound it was amazing!! I was trying to see if I could get a loan for one, Dave flew it multiple times that day and it got quiet a bit of flight time although he had two huge fuel tanks on board. He was doing some high speed passes a couple of feet off the deck in the dark with only a green light in the canopy and the heli was perfectly level and just booking at I'd say a good 70 mph. Personally, I don't think turbine aerobatics or 3D is great, what is the point? Just to say you have a turbine and money to blow or something? I've seen turbines 3D a couple of times now and I'd rather watch Jason Krause, Todd Bennett, Curtis Youngblood or Alan Szabo fly. Hey Big D is even cool to watch, I enjoy his flying as well. Big ups to Big D!

Less Feild equipment? I guess I am ignorant here. Since the only Turbines I have had the pleasure of seeing had way more field equipment than I care to have. (Jet Planes) They had this bottle that looked like a firebottle but it hooked up to the engine. (compressed air?) There was a plastic bag full of fuel that they had to feed the engine like an IV. I thought that the Jet Heli's needed this stuff too.
Oh and there was this hairdryer gadget one guy used too.

How do you start the Turbine in the heli?

always one in the group ken... i ask the same question actually.. id prefer to watch someone else fly theirs i dont want one nor ever need one for that matter...
I thought they used butane... i am under the impression that the compressed butane spins it up and heats it untill the fuel starts in.. the hobby guy in neunkirtchen (sp) explained it to jason and i but that was a while ago

jim BTW cool pics... hehehehe

volkul, that is the old school way to start helis or jets. They have electronic starts now just like the big boys!! All they do is turn on the heli, it initializes and then they move the collective stick up and then down and the heli starts up. No hairdryers, no I'v's or anything. The jet guys do attach a sort of header tank to their jets now, but only to taxi out on the runway without losing any fuel in the main tank.

Now that the PM's have calmed things down, lets bring it back on here. Your original post stated that in your opinion Turbine helis weren't much use except in a scale application and they needed too much field equipment to be practical.

You needed to get your facts straight before you made such statements and making your post in a different manner would have given you a different result. As Chris has said, they are push button start now, needing less field equipment than a glow motor.

You said they are not much use except for scale. That leaves FAI and 3D I suppose as the other potential applications. They are precluded from FAI at the moment as there is no category for them.

They make more power than a glow motor and the one I am working with now will turn 800mm blades at 1800 rpm. It makes 7.5HP, weighs 14lb and therefore will have a power to weight ratio 3D afficionados dream of.

There are problems still to be overcome in making it into the 3D pilots dream, but this is very early days for turbines yet and part of the fun is in the solving of problems.

How well a turbine will perform 3D is yet to be discovered, and wont be by me, but I hope to give this thing to a hot shot pilot to wring out and see what happens. Certainly I intend to use it as a daily fun heli and will be looping and rolling it and flying it inverted.

I know that the guy who has run 1800 rpm and more is bending blade bolts!

I dont think my cojones are big enough to get anywhere near that, but 1400 -1500 should be enough to have excellent cyclic authority over the mass of the rest of the heli.

To stress this heli to its limits will take some development on blades, holders and transmission. I'm looking forward to it

Hmm

How much, say, would the jetcat trainer cost? This is definately something I plan to get into. I can save up 2 months of salary for it! (I love being single! =P)
