Tiger Cub


The LSA Tiger Cub UL has a wide enough cowl to keep the exhaust inside, (no unsightly two stroke exhaust hanging out) a folding wing and tail, fully enclosed cockpit (large enough to accommodate a 6'6"-250 lb. pilot in comfort) full three axis controls with flaperons and a steerable tail wheel, a wide speed range and rugged landing gear.
The first Tiger Cub first flew on 1 April 1996.

The ailerons have a 2.7 to 1 differential throw ro virtually eliminate adverse yaw.
With a 447 Rotax engine a 170 pound pilot needs about 150 ft. of hard surface runway to get airborne, and will climb out at 800 ft per min. Landing roll out is under 300 ft, even with out brakes.

The airframe is built of aluminum tubing with aluminum gussets and brackets at the joints, fastened together with bolts and rivets. A drill and pop rivet tool are all that is needed.
The plans include a complete materials and vender list .
The material list gives a list of the sizes and amounts of all the aluminum and chrome molly tube and sheet needed to build the airframe, a list of all the AN hardware sizes and quantities needed and a list of all the rest of the materials needed to complete the airplane, with descriptions and venders part numbers for hard to find or describe parts.
The gusset prints are organized by thickness from .025 to .125 the patterns can be cut out and traced onto the aluminum sheet with a fine tipped marker. No scaling from the plans is required. Directions and tips for cutting out the gussets are included in part one of the assembly manual.
Full size prints, of the chromemoly and machined parts, are included.

The panel prints have all the measurements needed to lay out the part on your work table, so you don't have to scale your measurements from the prints, eliminating a common source of errors. ¼ scale prints (19" by 30" prints) of the wings, tail surfaces, fuselage and bulkhead panels.
The plans also include an assembly manual (over 200 - 11" by 17" ) pages of pictures and text), that gives step by step directions and tips to guide you through assembly, rigging, covering, wiring, plumbing and finishing.
Available since Jan. of 2000 over 300 sets of plans have been shipped (as of 1/2007).
Est. build time for scratch built...650 hrs.
Price for a complete set of plans was $250.00 in 2007.

The basic kit includes, a set of plans, all of the Parts Packages, listed on the previous page, and all of the additional materials needed to build a covered airframe (less engine prop instruments and paint.)
The kit will also include the main bulkhead, rear cross tube and the flaperon mixer, already assembled. These three subassembly's are the most critical and the most difficult to build. Having them built in drill guides and assembly jigs, assures a strong and square part, and reduces building problems considerably.
The basic kit eliminates the hassle of having to order materials from six or seven different sources and tracking down all of the numerous small parts needed.
