RE: What Can One Expect To Pay For...
Nick,
There are MUCH better ways to get into turbines than a FEJ F-15 with a Chineese turbine! If you go that route, you will be frustrated with a model that has many issues that you will have to fix and an engine that is not reliable.
For a low-dollar into. to turbines, build yourself an R-54 and get a used JetCat P-70 or Artes Super Bee - you will be MUCH better off!
