Improvements on V2 


The engine pod assembly has been changed and now sits atop a carbon fiber tube. All wiring between the engine pod and fuselage are now able to fit through this tube. The new engine pod consists of 3 pieces: the cowl, the bottom piece (to hold the supplied fuel tank and your throttle servo), and the magnetic hatch/pod cover. These improvements help contribute to the V2’s lighter weight (the V1’s ARF weight was 6 lbs 8 oz and the V2’s dry flying weight is only 6 lbs 2 oz).

A special compartment and optional hatch have been added to the nose. The hatch arrives out-of-the-box covered-over. To access the compartment, simply cut the covering material covering the hatch. This makes it easy to use this compartment for your radio’s battery or to add any necessary weight to adjust your Neptune’s CG. It is also the perfect location if you plan to install an onboard glow plug driver and battery in your Neptune.

The wing tip floats are now a bright red color. The V2 wing uses a Carbon fiber wing rod in place of the V1’s wooden wing joiner. The aileron servos are now safely located inside the fuselage (mounted near the center of the wing).
