Received mine yesterday.

received mine last Wednesday #027. I hope to run it this weekend

can these be used with the K45 or P-20 size pipe?

Thx in advance

Would depend on the pipe. My K45 is using a Grumania pipe that is for 40-80N engines.

Just intuitively, I'd say that definitely not with a P-20 sized pipe and most likely not with a K45 sized pipe.

These 70N engines produce almost twice the thrust of a 40N engine but with the same can and nozzle size. To do this, they have to move more air through the same opening - thus much higher efflux velocity. I would think that stuffing that much high velocity air (or trying to) through a small pipe would at a minimum result in a loss of thrust, possibly engine overheat, or worst case pipe collapse.

I would stick to a pipe designed for an 80N engine for the K-70 myself...

I just uploaded a unboxing and test run video on youtube.
unfortunately rcu won't let me upload any url's until I have at least 10 posts. maybe one of you can help me out and post the link for me.
should be easy to find: youtube unboxing Kingtech K70G
hope you like it

Here you go

thank you 70 ragtop!

Here's mine as well, had to do something about the stock settings as would not start on diesel from factory. have changed very little and have a record of what was done, I was very reluctant in changing anything to be honest.

I will say after watching that video of yours ragtop yours starts sooo sooooo much better, are you running diesel?. Mine is no where near starting right, it barely gets a temp increase on first burn and really struggles to get past the 72 degree ramp up, takes ages and sometimes fails.

Have a feeling I am going to have to contact kingtech eventually to get it starting right.

the one in the Video is mine, I run it on Jet A1.
It looks like you have cold ambient temperature in your video, that might cause a bad / longer start...

Cheers for the update on what fuel your using I thought it was running to clean for diesel.

Had mine out today and got it running/starting a lot better, settings are auto +1 and 68 pump ign,k. It's very close and a lot cleaner.
I am new to turbines and was wondering if cold diesel on a cold day would be a factor, today was 12 degrees C and after a few good starts on the above settings I put it back to factory auto +3 and pump ign,k 64 and it refused to start, hangs on preheat every time so a change was indeed justified and had to be made.

Ran it three different days now on the bench and feel I have made progress each time out and have a setting close enough to use now, of course would rather it just ran out the box but it did not. On the plus got quite familiar with starting a turbine.

Yes. temp makes a difference they are harder to light off on colder days . Once lit the fuel ring and injectors are heated to atomize the fuel. You will notice once lit off. it will start consistently unless it cools to ambient temp again.
