Hello to all,
I have a Jet Joe 1200 with semi auto FADEC. Mine came tested and then disassembled. I now have had over 400 minutes of run time on my Jet Joe. I am currently flying the the heck out of the plane it is on now. I have had a couple of hick-ups primarily with the combustion chamber. I then consulted JetJoe via email and then worked through them problem. Another issue is the front cover seal.(o-ring) I simply put a wrap or two of electrical tape around the front intake cover and then slid the case back on replace bolts then trim the tape with a razor blade using the case as a guide. I then use my lips to test the seal by blowing or sucking on the case/intake union if I can't pass air I have sealed. Any leak can cause significant thrust loss.

I have had previous expierence about 9 years ago when I built the Shreckling FD 3/64 and had success with an autoimously running jet engine. Building the Shreckling engine from scratch and them getting it to run was an accomplishment that has served me well with the operation of the Jet Joe or with any turbine for that matter.

Personally I feel that the engine core is solid and well manufactured but the combustion chamber (as with any turbine) are the weakest link in the engines healthy operation. I have a feeling that they are not assembled by CNC (computer numeric controlled) machine but they are hand spot welded together so some variance will exist. As well as the fuel rings which can be tempermental also. If you identify a problem with any component either the fuel ring or combustion chamber let Jet Joe know perhaps take a picture and they will more that likely send you what you need. Jet Joe has been very responsive to me.

Personally I could not afford any other engine and this engine has been a dream come true for me. We all know that there are other manufatures out there but if we can work together and we can help each other out and help the lower cost manufaturer (JJ) and help the hobby as a whole. If you cant add to this thread (Jet Joe owners thread) postitivly perhaps there are other threads about engines that never have any problems.

If any one needs help with JJ maybe I can help?
