FlexJet Pro Turbine Conversion Assembly Notes
The following is an outline of the steps needed to convert the FlexJet Pro ARF to a turbine operation. These instructions supplement the main assembly manual. Many steps can be accomplished in a different order.
Mount the Turbine
- Dry assemble and test fit the mounts.
- Fit the parts together as shown and check the fit in the model adjust the parts as needed for a close but relaxed fit.
- The Turbine may be mounted with screws of the modelers choosing. We used 4-40 SHCS's with Blind Nuts. Others may choose Sheet Metal Screws (#3 or #4)
- Doublers are provided to thicken the screw area.
- A PLATE is provided to substitute for the Turbine during fitting and gluing. Typically it can be mounted to one side of the turbine mounts, installed in the model, then the second turbine mount can be screwed into place.
- Once the parts are fitted, glue the mounting rails to the sub-formers as shown.
- Install the mounts again and glue the sub-formers to the fuselage with Epoxy.
- Use a 15-30 minute or greater epoxy. You can use a thixotropic epoxy such as Hysol 9462, or thicken conventional epoxy slightly with milled glass fiber.
- The exact fore/aft distance of the mounts is set with the 105??mm long plywood strips included which go forward to the main landing gear mounts as shown. These can be glued in at a convenient time with CA or Epoxy. (Make sure they are far enough into fuselage so they do not interfere with Door Actuation).
- Fit the parts together as shown and check the fit in the model adjust the parts as needed for a close but relaxed fit.
NOTE: that KingTech recommends running the engine outside the model with the assembled equipment tray and fuel system. Flex Innovations used this procedure and had complete success.
Turbine Selection
- At the time of this writing, Flex Innovations has tested the KingTech K45 G3 and have found it to be a perfect match.
- The Zicoy X45 is very similar, and its mounting was considered in the design. It should be easily fitted as well.
- Flex Innovations in no way recommends turbines with greater than 4.5kg thrust.
- Turbines have very high exhaust gas velocities and can reach high speeds. Throttle management should be used.
