The J-10 was designed specifically for the JC P-180. When I looked over CARF's J-10 at BITW the two long carbon rods had the 3mm threaded rods glued to the ends in order to reach the servos and thrust vectoring tube. The threaded rods connecting to the thrust vectoring tube were bent following the profile of the turbine and connecting to the tube via ball links. They added shrink tubing around the glue joint overlapping the two rods and inch or two which was directly over the middle of the turbine to protect from heat. They have a picture of the turbine mounted to the rails and linkages in the latest CARF catalog. I can take a picture of it and post here if that helps. I have the kit and plan to start building it soon. I just received the gear yesterday. Main tires are 4.5 inches in diameter.
