Advanced Pilot Seminars has been offering a money-back guarantee on the Live Course for over 13 years. So far, not one of the thousands of participants has asked for their money back--and that includes OEM representatives, FAA personnel and engine manufacturer reps, engine rebuliders and hundreds of LAMEs. Not one--and some came as seriously doubting Thomases.
We have also offered a $1000US reward for any repeatable data which is offered to contradict anything we present. So far, no takers.
If you don't believe what we present and what Jabba or Deakin or I say, why not take us up on that offer and offer your data?
If anything we present can be proven wrong, we want to know it more than anyone--and we're willing to pay for that education.
Remember that, without data, all you are is another person with an unsupported opinion.
