GREAT PLANES 25% SU-31 1.30/43cc PERFORMANCE SERIES ARF
A fully 3D and IMAC Capable Crowd-Pleaser!
The SU-31 is one of the most popular designs for precision flying, and the Great Planes Performance Series ARF model of this aerobat is sure to be one of the most popular planes at the field this summer! Expert engineering ensures the lightweight strength needed for executing high-stress maneuvers, and ARF construction trims final assembly to just 20-25 hours. Extreme pilots will want to check out this big, beautiful bird! An ideal balance of low weight and high structural integrity combine with all-wood construction, featuring a painted fiberglass cowl and wheel pants, to make the SU-31 a great sport model – but also one that is capable of 3D and IMAC aerobatic maneuvers.
• The Fuji Imvac BT-43EI with its easy- starting electronic ignition system gets a “thumbs up” as a great choice for a gasoline engine. The O.S. 2-stroke 1.60 FX maximizes the SU-31’s potential by keeping weight down while supplying plenty of power. Both have been extensively tested in the model.
• The turtle deck and fuselage bottom are constructed of a precisely sculpted foam shell that is reinforced with balsa sheeting, adding strength and great looks.
• Instead of the flat tail surfaces offered by other manufacturers, the SU-31’s tail surfaces are airfoiled. This delivers excellent control response and superior maneuverability at all speeds, in all flight attitudes.
