Introduction
Thank you for purchasing the Ultimate FX 3D ARF, a three-
dimensional vacuum formed fuselage version of the original
E-flite™ profile Ultimate. The stiffer fuselage construction
means less flex making this model better equipped to handle
outdoor flying, yet it’s light enough to still fly indoors. The
Ultimate FX 3D is a great freestyle aerobatic foamie and has
added carbon fiber support stiffeners for reinforcement and
added wing support to make this a great outdoor 3D foamie.
We provide a 6.6:1 gearbox and a 12 x 6 propeller so you
can easily add our E-flite Park 370 Inrunner Brushless Motor,
4100Kv for high extreme performance. Like many other
E-flite models, you will not be disappointed with the added
features such as a painted lightweight fiberglass cowl, formed
wheel pants, and a pre-painted trim scheme.
