RE: FEJ 1:6 Scale J-10 Vigorous Dragon Build
Almost there! Since everything has been built in sub-assemblies, completing the aft section of the fuselage has gone quickly. Mounted the exhaust pipe, turbine, and all related turbine valves, pump, and ECU. Then I connected the rear fuse to the forward fuse with the supplied screws.
Time to check the CG. As you may remember, I assumed all 4 A123 battery packs needed to be as far forward in the nose as possible to balance (based on my old Eurosport of similar size). WRONG! At the recommended 300mm back from the root LE of the delta wing, I am way nose heavy…. I had to remove the “lighting” A123 battery pack (lighting will be installed this winter due to a delay from Details4Scale). I also moved both receiver A123 packs back 2 feet and slid the ECU A123 pack back 3 inches! Not sure why it was so nose heavy; perhaps the rear of the jet (ex. rudder) is way lighter than the Eurosport due to the “honeycomb” construction of the J-10 or the nose of the J-10 is heavier due to the full cockpit and operating canopy.
