I believe that you are asking about ducted fans...right? I have to respectfully disagree that the F-16 overall is a poor choice for a first jet. Some are good for beginners---some are not. The Byron F-16 has a well known reputation as being one of the easiest F-16's to fly.

If I were you I would get an Avonds F-16. You can purchase it as a ducted fan or turbine version. If you get the ducted fan version you can buy a turbine conversion kit from Philip Avonds and go turbine later!!! This model uses a Dynamax fan unit. The Dynamax ducted fan hardware will be very easy to sell at a later date due to it's popularity. This model is very easy to build and fly. It uses "Tailerons" only for pitch and roll control. I have one now under construction.

Although the Byron F-16 is a very good flyer it is not a good choice to try to convert to turbine use. Additionally, the Avonds F-16 is very scale. Mr. Cherry---care to chime in here...
