I understand the ducted fan route as #1 choice, but after investing in turbine and plane , one would hate to spend more money on a ducted fan plane and then not use it after the turbine waiver exercise is done. Many of us are from r/c clubs that dont dont fly ducted fan planes so we can't borrow a plane for the waiver exercise. A Quickie 500 is pretty fast ( 120+mph) but with no throttle control , landing is always a dead stick affair. There is a big difference between landing on grass and on pavement! Many of us fly on grass fields , so finding nearby clubs with hard top surfaces to practice landing is not all that easy. There need to be some compromise to help us who would like to get into turbines.
