The McLean Extreme

 

Brian Mclean made this ship for F3F, DS and any high-performance sloping.

The fuse has a slip-on nose cone over a carbon servo tray insert, a removable carbon ballast tube, and a unique mid-tail fixed horizontal stabilizer with elevators. The linkage in the tail allows up-elevator with a servo pull, key for heavy DS elevator loading. The fuse is heavily reinforced glass, with thick Kevlar in the wing root section, with Kevlar and carbon extending from the wing root trailing edge to the tail in the boom.

Wings are carbon over  high density foam with a ply reinforcement of the leading edge and a heavy ply root and sub-rib. The DS19 airfoil and wing planform was custom designed for Brian by Joe Wurts for F3F and DS.

The kit comes with both carbon and steel joiners. Ailerons and flaps are silicone-hinged with internal balsa wipers, and the molded rudder has an internal wiper.

The Extreme fuse is carbon-fiber, fiberglass and Kevlar. It has a slip on nose cone and a strong carbin-fiber area for the battery, receiver and fuse servos.

The elevator is mid-T. The horizontal stab is fixed in the front and the elevators are actuated by a linkage that allows the servo to pull for up elevator.
