My views have always been that the JJ1400 can be a good little turbine if set up properly, mine has never failed to start or run and has about 50 flights todate in my bobcat.
I have spoke up in the past on this thread saying that the later engines are now made from the proper materials etc and all the past problems were due to faulty components which everyone knows. Also I can only comment on the 1400 which I have personal experience of.

The Combustion chamber shown above does not have inconel vapour tubes, all 1400 are supposed to have had inconel tubes for nearlly 2 years now so maybe this is of a different engine or a earlier model.

What I have come to realise recently that the real negativity against JetJoe is due to the blatant copying, I was always thinking it was general knocking of jetjoe selling a cheap turbine and issues over the components, and the how the turbines run, and is why I have always given my views as I mine has always ran fine.

Just recently because of this I done some research myself and the 1400 is vertually indentical to a wren 54 mk3 and basically all parts can be interchanged. I also have a wren mk2 which is bears no real ressemblance to the 1400 but maybe it did to earlly 1200's.

Maybe I was nieve in the past as I always thought that the reported copying was really just a similar design and people were getting wound up with a jetjoe selling a cheap turbines.

Now that I see it first hand for myself, I cannot support that, I stand behind Wren as with Gasper as I think JetJoe should have at the very least stuck with buying in ECU's rather than copying them as well and making another promanant supplier in this small turbine world angry.
