Legacy - 85" Muscle Bipe - Yellow/Black - RADIAL

Equally at home flying barnstormer airshow maneuvers as it is flying old school low and slow 3D, the Muscle Bipe's gentle manners inspire confidence for sport flyers and 3D enthusiasts alike. Styled from the classic WACO UPF-7, the Muscle Bipe has gorgeous golden age/barnstorming looks married to modern aerobatic performance.  

This radial engine version is designed specifically for the Saito FG-90R3 gas radial and includes a bolt-in baffle to aid in cooling the engine cylinders. To provide proper mounting for the FG-90, the radial version motor box is 2in./50mm shorter than the 70-76CC twin version. Get that SOUND in a fun, easy and aerobatic biplane with the radial Muscle Bipe.  

The Muscle Bipe features quick connect mechanisms that allow it to be assembled and disassembled in a couple minutes at the flying field-without any tools! No more long and tedious assembly and tear down sessions that are typically associated with biplanes! The Muscle Bipe features our state-of-the-art construction materials and methods, resulting in a lightweight, rigid and robust airframe. It features carbon fiber wing and stab tubes, carbon fiber landing gear and tailwheel assembly, carbon fiber main wing spars and fuselage longerons, g10/lite ply composite laminated internals and 2 gorgeous genuine Ultracote (Oracover) color schemes. Highly prefabricated, including pre-hinged and sealed control surfaces, the Muscle Bipe can be assembled in a couple evenings.

Be sure to add this awesome padded wing bag, to your order! Designed to fit all 4 wings, both stabs, outer wing struts and the carbon wing and stab tubes, the Extreme Flight padded wing bag will ensure that you arrive at the field in style with your airframe intact!

CG Note: when using the FG-90 radial, the CG location will automatically fall at a slightly nose-heavy, very comfortable CG for barnstorming and sport flying. We recommend using the rear (push-pull) rudder servo mount and placing your batteries on the tray under the cockpit. Because the system is well known and tested, it is not necessary to check CG on the ground.
