Hi Jim,

The engine you mentioned that they charged you one hour labour for, although still under warranty, was that the one which was clogged all over at the inside (needles, filters,...) because of using unfiltered dirty fuel ?
If so, I would also have charged you the bill which is in my opinion and considering such information even very reasonable. Friendly pun intended !

Happy New Year to everyone !

Nicolas.
Hi Nico, Thanks, I did not want to go into my problems with that issue, since I was sure it would lead to discussion off topic & did not want to air my issues with Wren in public, but since you bring it up, I am forced to go into detail. Not sure if it was that turbine, or the other.
On that particular engine, I installed it in a brand new FeiBao Panther, with all new tanks (washed out), plumbing & BVM UAT. The jet was lost when the turbine stopped after three minutes. The turbine was placed on a test bench, it would run for three minutes perfectly well, idle or full throttle, then stop. It did this every time. Wren asked me to try various things to try & cure the problem, including removing the fuel filter under the front cover to check it. The filter was spotless, but was changed anyway. It made no difference. I was somewhat annoyed at losing my jet & sent the turbine back to Wren. There was never any ''clogged all over the inside'' or clogged needles referred to at all. After having the turbine for over two weeks, they came back & said the fuel filter under the cover was totally blocked & sent a photo of this congealed mess of a filter, which I can assure you never came out of my turbine. I had just examined it as requested & changed it prior to shipping it back.

I asked them how such a filter could be mine, when I filter my fuel twice before filling the models tanks. I also asked how all this supposed crud can go through a new BVM UAT, totally clog up the filter & with a new filter fitted, still have the same thing happen & the turbine still run perfectly at full power for three minutes, then stop. They never answered these questions.

The same fuel was used in my Wren 54, Supersports & 44 with no problems.

They billed me for one hours labour, plus the cost of a new filter. At the time, I was fuming. I had lost a new jet & found it incredible that a company thought it worthwhile to charge for one hours labor on a new turbine & wondered if they had thought it worth it in terms of customer relations.
I had been a lifelong customer of Wren, buying a few turbines over the years.
I do not want to get into any discussion about this, as it happened a year ago.
