Here is my opinion on the JJ1400:
I bought one as i couldn't afford another more expensive engine, for getting in to turbines.
I just couldn't spend 2500 dollars for getting started with the knowledge i had at the time.
It worked alright for a newbie but not anywhere close for fitting it in a plane.
After sending it for repair somewhere it seems that i need a new NGV abd a fuel manifold.
The NGV's tolerance was out of spec a lot and i dont remember stressing the engine.
Bottom line is that the engine is a real bargain for those who know well about turbines (my opinion) but
not for newcomers like me.
I am sure that if someone knows about turbines he can get a JJ1400 kit, assemble it him self and he will have a very nice and reliable engine.
Never the less buying the JetJoe JJ1400 provided me with enough knowledge to go on with confidence despite the problems i have.
I also think that the price drop on major turbine brands like P80 and the typhoon 70 is not an accident
but a result of competition .
Now i can get a Funsonic or a JetCat from inside Europe for ~1600 Euro which is not that bad if i ever need another engine.
This was just not possible a couple months ago.
