I agree with Vince,
this really getting out of hand. You don't see people getting upset when a pilot hovers his 30lb extra 300 near a crowd swinging a 3' propeller. Typically, most jet pilots don't take unnecessary risks with their models.
It has always been recommended for anyone starting with this hobby or advancing in the hobby to seek out someone with more experience.
And it is true that if you want to fly your turbine in a "PRIVATE FIELD", you do not need a waiver. Although, look at getting a waiver as a learning experience. There's always somebody that can give you good tips on the operation and safe flying of a jet.
