- pdelbarba 9y agoAt this point it's mostly certification cost and liability insurance cost that's keeping the tech back. You can easily modify modern aircraft engines to be more reliable and efficient (PMAGs) but you need an STC (certification procedure) to make the switch so the experimental home builders are the only ones who actually benefit.
