Well let's finish this:

PST repaired my turbine but the cost was too onerous for me not for them, also shipping cost was horrendous. So I opt to sell them back the engine.
They had the chivalry to accept the deal.

I personally recommend these turbines. They run good and the thrust is as expected and advertised. The only thing missing here is a good U. S. representative.
They answered all my E-Mails professionally and were very helpfull. Good people to deal with.

Congratulations for such a good product at a great price.

Regards,
Juan.
