Thx !

Got the number and talked to Dirk, don't think there's pre-orders just yet.

The K-45g can squeeze into a Habu 32 !!!!

K70 is 5 more lbs of thrust in similar package

Ceeray

How the extra thrust is achieved in these smaller ones? Higher rpm/fuel flow/temp? And that way lower expected life?

Anyways, twin engined models just got lighter!

Larger compressor and turbine, probably same RPM. I would say there are very fiew parts that are the same due to the larger inlet, outlet etc.... Life should not matter if they made their homework.

I might need to think about this little turbine for my L1011 project. this should keep a whole lot of lead out of the nose. looking forward to seeing it in Kentucky

Will be a nice turbine for my Christen Mirage 2000

coming soon.

Ceeray,

KingTech turbines may share the same Turbine housings and front covers on a lot of our K class turbines, but I can assure you that "all" of our turbines have different internal parts. We do not achieve more thrust by cranking up the RPM and running them on the verge of failure and prematurely wearing them out. We don't sell ECU RPM unlock codes to crank them up for more power.
KingTech Turbines achieve higher thrust and now in much smaller packages, by the Compressor blade, Turbine wheel blade, NGV, fuel injection delivery systems, combustion chamber designs. It seems our Engineering team has been brain storming and achieving some really awesome cutting edge, game changing turbines for our hobby, and lets not forget about our awesome Electronics package that was recently released. I will say that from day 1, KingTech is not quick to put a product out, just to put it out because we want it NOW. Once they have completely tested, tweaked, tested again and even tweaked some more and run them for countless hours (did I mention more tweaking and testing) to make sure we deliver a high quality, reliable turbines, at affordable prices, then they will release it. I hope this sheds a little light on this question.

Cheers,

Dirk

You can actually tell just that from the above picture of the K45 and K70 next to each other - notice how the starter motor sits differently and the can is slightly bigger, different exhaust cone, etc. There's a larger rotating assembly in there - or at least a significantly different shape.

These 70 class engines are exciting - and am looking forward to their release - can easily build home-designs around them, inexpensive retracts, etc.

Just cool.

I used to have a Marcel Lahaie Mirage that this would have been perfect for. Wish I had of kept it now!

I'm thinking my 89" A-10 might go from EDF to turbine power.

I'm in for light, low and slow....or crazy fast....This new "70" (K or M) small engines coming soon sure will be game changers. Don't forget your new CG/ center mass gap when applying flaps if you downsize engines on an existing plane

Ohhhhhh YEAH, Oh F... YEAH

Finally an engine producer woke up and starts to fill the blinde spot on the market, excellent job guy's!!!

Hopefully the airframe designers will wake up as well!! (Come on Carf, start producing the mini Flash!!)

Midas D.

Ooops dubbel post , but again, Excellent Job !!!!!!

Henke Torphammar

There are allot when you look around, but they are hidden/forgotten as they really did need more then a wren 44 but too small for 80N size. Skymaster EDF Viperjet, F15, F18 etc...... Blackhorse, Phoenix. They do excist, but I agree it would be cool if CARF did smaller too, not only going for the 300N ones.

Midas D.

Maybe we all should start Bombing Carf with E-mails to shake the tree and wake them up

The least they could do is start producing their Spark again, the molds must be there somewhere under an thick layer of dust...

I just pulled the 90mm edf unit from my Sub-Sonex in anticipation! BTW, my K60 is working flawlessly in my Tsunami 60!

It would be great to see a spark on their catalog, but wouldn't the 70 be to much for it? some time ago I was thinking on it with a 45...

Midas D.

Hi Skymaster,

Got the Spark, i was one of the lucky few who could get it's hands on a brand new out of the box one

Got it with the K45 setup, Jet-1A gears and Grumania pipe in it.
It's ready for it's maiden.
Had it out to the field for taxi test and all looked fine but think it would not hurt to get the K70 in there, especially cause i'm flying off grass.
Although the original Carf supplied tank in there is quite small, so it will be short flights with a K70

Now the only down side is......... When i got it out i was just to chicken to maiden it, pure frightened by the thought's of a possible mistake and a possible damage or crash....
And then no more spare's available........

So being the lucky owner of one now has a down side unfortunately, cause she kinda feels to precious to waste....

rich I certainly hope you're not planning to install the k70 in your sub sonix The 45 is far more power than that airframe needs
in my mini of avanti I hardly get above half throttle only using full throttle for take off and some verticals. Still looking for the short kit of the sub sonix to become available have fun

I too have one of the last new in box CARF Sparks. I remember seeing these fly at Florida jets with the wren 44. I have a grumania pipe if anyone is interested as I have decided to still keep it electric

Henke Torphammar

There is never too much.... It depends more of which weight you want to stay at. In my mind it makes little sense choosing a K45 as the K70 would be too much. All turbines are equipped with a variable throttle function that is very easy to manover while flying. Full power is used going up and lower settings going down. With practicing you will learn to master this incredible feature seamless :-)

I've seen the 1.9m Futura with a 200N+ engine. Makes perfectly sense if you throttle it. (this particular engine still uses the same amount of fuel for the same flight times as the 100N options so no major weight penalty)

Set it up clever and use throttle, power is fun!

Dupe post, sorry

TTRotary

looking forward to this new engine. And, put me in the camp of those wanting smaller airframes that are designed for these smaller engines. I'm sure many will disagree, but I find the manufacturers' insistence on pushing large airframes problematic, and ultimately self-defeating.

There is a HUGE market out there for turbines, IF manufacturers will produce smaller ARF kits. Most of us don't have access to huge fields, or want trailer and large vehicles. Many of us don't want to cart around 10 gallons of kero. The average paved field is around 500-600. And with more fields closing every day and more restrictions on turbines, it makes sense to fly smaller models.

At at the moment, the only military jets for the K45 are the CJM and JHH kits, which require serious building skills. Wouldn't it be nice if KT/Pacific jets worked with one of the Asian manufacturers to bring us 65-72" size Mirage, F-16, f-15, -18, Panther, etc. The Sky-e-master series is nice, but the model offerings are too limited. Tam's F16 was great, but is out of production.

​​​​​​​Come on manufacturers, bring us some smaller jets. If you want us to buy more engines, given us something to put them in!

Hello Bob, I have the chance to get a nib spark here at my club, the owner quit the hobby and I just emailed him to buy it.. If so, I'll be interested on your grumania pipe, please Pm me with the cost of it.
