RE: Beging whit DF or Turbine?
More like the next step, if you think you are a good pilot, can handle a fast plane and are a meticulous builder just go for it, no need for the D/F pain and agony, a turbine is the way to go been more reliable than a D/F engine and you are bound to be successful and enjoy this part of the hobby.
happiness on your next quest.
