Enigma F5J 4m

The Enigma F5J is a beautiful 3.95m F5J glider from Russia. A well engineered and attractive F5J competition model with an excellent flying reputation. The finish is nearly as good as that of the top manufacturers and the performance is first class.

The Enigma major innovation is a very nicely engineered V tail designed for tail mounted KST X08 servos. The elimination of tail pushrods combined with the supplied lightweight tail wiring harness means this configuration does not need substantial extra nose weight, but the RC installation is considerably simplified and the whole of fuselage front is available for the powertrain and ballast.

The fuselage 99% completed with the firewall fitted and just the tailboom to be fixed to the forward part. A substantial ballast tube 55 cm long with an internal diameter of 16 mm is ready fitted. The fuselage is a nice simple design with ample space for the powertrain, receiver, and ballast.

The wing is has XPS foam cores with chequerboard spread carbon skins. The wing spars are improved and are substantial. The wing colour schemes are stylish modern faded designs usually with contrasting white underside stripes. A well made and very lightweight wiring harness built into the wing, with the plug already mounted.

The accessory pack includes wing control horns, clevises and pushrods. And wing and tail servo wiring harnesses as previously stated. The plane is sometimes/was previously called the Skiff and some links give that name. See this very helpful RCGroups Enigma build thead.
