Did you buy both turbines new? Looking at P-20 serial No it looks like a 2013 turbine. When was the P-100Rx made? JetCat offer a 3 year warrantee, I have seen turbines that have only run 2 hours in the 3 years, the warrantee is not hours, its years. Its hard, but they cannot be expected to make the warrantee 4 years or 5 years, just because its not used! Actually I have seen its worse for possible problems little use, bearings can stick with no use, then they slide for the first part of the early re runs...then later bearing failure. Bearing O ring mounts can perish and then like you have the compressor touches.

For sure posting on RCU does little to make them be sympathetic!

No one in this hobby likes anyone in the 'jet family' to have down time and problems, but some things are unavoidable.
