The JHH Mirage is actually pretty easy to convert to turbine with minimal reinforcement. My Friend (George Leu) and I took my old airframe that was flying with a .45 fan unit and recently converted to turbine using an old GWM FD3/67 engine. I am waiting for some better weather conditions to test fly this plane but am confident that it will be phenomenal. I mounted the turbine all the way in the tail and still balanced the plane without any nose weight while saving a lot of weight by excluding the bypass/tailpie etc. The wing is all builtup as per the instructions. The total weight of the airframe is around 9lbs dry with accomodations for 64 oz. of fuel. I believe this plane was the subject of the RCJI magazine a few issues back. The second part of this article is waiting for some flying experience and pictures. Here is what the plane looks like currently.
