Profile Ultimate

About

The Profile Ultimate is a profile-style electric foam biplane in the Gordon Price Ultimate 10-300 silhouette — the Canadian unlimited-aerobatic biplane that Price designed in the 1980s to compete with the new generation of monoplane aerobats. "Profile" construction is a distinctive RC category: rather than the rounded fuselage of a scale aircraft, the airframe carries a flat slab-sided fuselage cut from sheet foam, which dramatically reduces weight and side-area while preserving the wing-and-tail proportions of the subject aircraft.

The result is the kind of high-power-to-weight ratio that profile-style foamies are famous for — capable of unlimited 3D handling at a fraction of the mass of a scale balsa Ultimate. The Ultimate biplane silhouette gives the model the visual signature of a real aerobatic biplane while the profile construction makes it forgiving in the kind of cartwheel landings that come with 3D practice. Symmetrical airfoil, oversize control surfaces, and a brushless installation drive the kind of hover-and-torque-roll handling that twenty years ago required a dedicated balsa biplane and a long building winter.

The bigger picture is the profile-foamy 3D category itself. Profile Ultimates, profile Edge 540s, profile Yaks, and profile Pitts biplanes have become a distinctive niche in the foam-3D market — flat construction, biplane visual signature, and the kind of aggressive handling that suits indoor and small-field unlimited 3D practice.

In the simulator

A demanding profile foamy with the kind of immediate response that flat-construction airframes provide. Use it for unlimited 3D vocabulary at park-flyer scale: hovers, harriers, torque rolls, and biplane-specific snap rolls. A natural sibling of the Ultimate Bi-Plane (3D Planes pack) at a more accessible profile-construction scale.
