Iguess that the evolution model of K-30 will be K-50.....i hope so...LoL.

I'd buy two if they were priced like that !!!
Gone are the days of 3500 dollar 90 mm sized jets with a turbine in it !!
I wonder who makes pipes for these, Motion should do a conversion kit for their set of 70s and 90s
Exciting news

Adding lead will be needed for most planes swapping to a K30. So 1lb of lead and 1lb less power with a total of maybe 2lb more weight.... very possible but VERY stressful for the China undercarriage.
Some planes do have proper struts and some don't. The choise of airframe is just much more narrow going heavy on the engine. I would call it impossible for MotionRC to make conversion kits. Even I who did like 30 different kits by now don't se how....
but maybe Motion or Taft or FMS or what ever decides to make planes for conversions at the start of the design. Then we are talking.... but so far I don't know of such projects. Well HSD, but they have a long way to go......
better go glider, 3-4m scale or the Opus vjet or phoenix Preceptor or something else that does well on less power and are not sensitive to weight.

Nothing is gone, just more added to the mix. With such a large engine you need the right airframe. Even with the Kolibri it'sseriously hard to get fuel at CG and keeping the AUW low with no lead.

There are plenty of YT vids of T-30s inside of FMS and Freewing 90 and 70mm sized models just no one wants to pay 3300 + all up cost seeing the engines are in the 2300 - 2800 usd range for the Kolibri's
1200 range for the engine makes a conversion considerable

Yes, but now the important wrap up of my previous post. The K30 is larger and heavier which makes the choose of plane critical. There are those who will be very good but simply not the Freewing range. Most are a pain to get right even with Kolibri. Power is not the problem but getting the CG and saving the life of the retracts. If you know what you buy you will be happy, but frankly few do.

FW 80mm Avanti fits p-20 just fine without any heavy mods to the fuselage so the larger FW and FMS 90 mm models (you're right, 70mm models would be harder) should be less of a pain.
Would be worth someone doing a conversion kit for ease.

Life is a trade off. No doubt Kolibri is amazing. I would own one and be willing to pay the price for one. If they had US service or even European service that had good reports. I am not willing to pay that kind of money and then have to send the engine in and hope it comes back within 6 months. The KT is a little bigger and less power. It will be cheaper and if I have a problem it will likely be back to me in 2 weeks based on my exp[experience with KT.

"The K30G also runs on diesel
It weighs 399 gr with integrated Kerostarter, valves and Fod
As a connection there is only one cable and one hose"
From a kingtech dealer, mmmh have a preceptor at hand. Would have been nice to have valves external etc and manual start to keep weight down for the reasons Henke described but still plenty airframes this little jet could fly.

Now we need that awesome price

I have a 90mm Fly Fly Hawker Hunter kit arriving soon which I will fit decent electric retracts into and the KT30 when the first one is available in SA. I believe the hunter is ideal as the CG is pretty much in the center of the fuselarge so it makes balancing the model easy when the turbine is mounted at the rear so no need for a thrust tube. 399grams of weight at the rear should equal 450grams in the nose which is a decent size lipo for rx power, the turbine pump and a few grams of lead. Fuel tank on the CG
So if you choose the right model I'm sure that the results with the K30 will be spectacular.

The Hunter got the longest thrust tube I have ever used by factor 2!! 700mm long. This to obtain CG with an air started Kolibri with no extra weight. Also the hunters fuselage is really narrow, you will find it hard to get fuel in there. A friend did the full glassing thingy with his, but he spent so many hours doing this that it simply did not make sense. Still flies good but not a lot of foam left when he got the 800cc tank in there. This also with a Kolibri front mounted with thrust tube.
If you go tail mounted, the Hunter would be my last choice! Better go with our 40mm thrust tube and you will not loose any thrust even at 700mm length. (I always test stuff so I know)
CG is at the rear of the NACA duct, this makes for a 2:1 ratio or so where 450grams added in the rear(engine + mount) will need 1kg more in the nose. This makes 1200grams over my weight in a perfect world. Then you would want addons as flaps, retracts (Im sure), all the reinforcements needed to go up from 650CC of fuel to a more resonable 800cc..... you are looking at almost twice my take of weight. Even though I know mine is a bit extreme, the thought of going twice the weight is mind blowing.
