Dear Delahaye 53,
Why are you spreading up such a bad comment against Simjet ? The fact they are very busy with UAV market does not mean that the company is no longer handling customer support. I am sure that you do know where the Simjet customer lack of support in France is comming from? it's not a reason to blame the turbine manufacturer. I can tell you that still many Simjet turbine are running trouble free in Southern France.
Please feel free to contact me should you need any support with your Simjet turbine.
