EasyTiger,

I understand what you are saying. The engine I have, to my knowledge has at least 2 trips back to China. The first time you sent it for servicing. They made some changes and gave it a clean bill of health. Then, I bought it from you, it started and ran at idle, full power or inbetween. It just flamed out if you throttled up or down at more than a snails pace. JetJoe checked their service records. They found that they had installed, for you, the older CC which they found the problem I described. Their latest version apparently cures it. So I sent it away for upgrading.

I asked about testing of the engine. JetJoe tells me that do 3 starts and runs of 10 minutes. They run the power up and down on it. This makes sure everything is working as it should. They also tweak the ECU settings. Being winter here, I have not had a chance to run it since I got it back from China. The bill, including postage two ways, was nearly $300 cdn. Not a cheap fix.....(and it didn't include the autostart bullet starter. still waiting for it in the mail. HINT HINT)

I will run the engine, next summer, and see what it does on the Reaper. I have invested too much in it to sell it. I would get, what, maybe what the repairs costs me????? So, I'll run it till it explodes or dies again....

I will watch this thread and see how others make out. Once, I hear of hundreds of flights, without hiccups, then I might consider a second JJ1400. But not till then.... Or, the one I have last a few hundred flights.

Thanks,
