Kingtech K-10TP
 

Hello.

I posted this on another forum where giant scale flyers meet, but since there is no dedicated jet thread there, I thought this perhaps would interest some of the users here, as I have found very little info online myself.

For those that are interested I have listed specs and performance of the Kingtech K-100 Turboprop below.

Weight of engine ready to run, incl. FOD screen and prop bolt/washer: 3.578g / 126,2oz.
- (Kingtech states 2.850g / 100,5oz, so that´s something to be aware off if you intend to buy one.)
Weight of ECU, fuel pump and wires: 285g / 10oz.

This will replace a 3W-210TS on a towplane, so I decided to test the same propellers to compare.
Fiala 34x14x2: 5.600 on the 3W, 5.400 on the Kingtech.
SEP "Wilga" 32x14x2: 4.450 on the 3W, 4.500 on the Kingtech.

So it´s seems that the power is a little less at high rpms, but about the same at the lower range.
This is good, as the primary goal is to get a powerful quiet setup, which means low rpm, to limit prop noise.

Eventually it will be equipped with a 3- or 4-blade Varioprop so I can dial in the required pitch to top out at about 4.500 rpm on the ground.
This provides a buffer so I don´t overspeed the gearbox in the air.

I run the engine on diesel with 5% Kingtech oil, and after a bit of fiddeling in the ECU it now seems to start up and run nicely.

I now realize the thread title had a typo, but a 10N turboprop would be cool!

Nice Yak.

Yeah, I only noticed the missin zero after posting, and I can´t edit the title it seems. :-)
On the other hand, Kingtech does plan to have a K-30TP in the program as far as I remember.
