I know this thread is on the J Jr. but I thought I would post something on another Jet Joe turbine as FYI. A few weeks ago I ordered a refurbished JJ 1800 from Andy at CRX Turbines (www.crxdesigns.com
). I got a refurbished unit as it was what fit my budget (I am retired and on a fixed income). I got the engine earlier this week and ran it for the first time today. This is my first turbine and I have to say that I think the engine performed really well. I got the autostart and it worked just as advertised. I had a long time turbine guy helping me with it and he commented that it ran well, was balanced and the throttle repsonse was very good. I could not be more delighted.
Littlepiston, sorry for posting on your J Jr thread and I hope you don't mind but I thought I would offer my experience with the JJ and Andy. Now I just have to finish the plane.
