Hello Shai,

Yes I replied but the maildelivery system kept sending it back. I think because of the size of the pictures. I think you have received it now.
Here is a picture of the engine wich can be found at the museum near the airfield Seppe in the Netherlands.

re: Minijet J-3

Hi,

...an other question:

are these gaskets still available? It looks to me as a copper gasket, filled with a heat resist material. Could this be some kind of asbest?

thanks,
Pieter.

re: Minijet J-3

Hi! Thanks for the replies. It's nice to know about the $400 but it doesn't realy matter. It is not for sale anymore. However, I do have some more questions. What kind of fuel would be the best to use? How long would the valves last, during a static run? I made an ignition system with a coil and som...

Minijet J-3

Hello! I found this minijet on a Dutch internet marketplace and bought it! It is complete with sparkplug, drawings and guarantee card. It is in un-used condition. It is made in 1946 by Minijet Motors in California. I wonder if there are a lot of these engines sold in the Netherlands or Europe. What ...

re: Marten Klein and K-PT 07X in the news!

Marten, it is a PJ90 copy indeed. Worked very well at the moments I started it. It is hanging at the roof of my garage at now, as a "I am so prood I built this once" tropy, but it should realy be used for R/C flying. Maybe in the future. Milisavljevic, nice to know you also came back to this forum! ...

Hello everybody! It has been a long time ago since my last postings on this forum but some of you might remeber me. Marten, was there anyone who was flying pulsejet powered RC-planes during this event, interested to fly a plane with a valveless engine? Check out my website to see the pulsejet I buil...

Shchelkin spiral

Hi everybody! Would it be possible to make a Shchelkin spiral?

This is what I found ...

re: Strahltriebwerk AFM 500

...maybe it was the smallest spark plug they could get when it was made. I think it looks great. Did you already run it?
