Tiger Cub aircraft plans

Designed to meet all the conditions of Far Part 103 with a F-33 Hirth engine. The Tiger Cub UL has, 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 flapperons and a steerable tail wheel, classic looks, a wide speed range and rugged landing gear (standard design features). 

With a F-33 Hirth engine a 170 pound pilot needs about 300 ft. of short grass runway to get airborne, this same pilot can expect a 600 ft per. min. climb on a standard day and an 8:1 glide ratio. With full length flapperons you can float out or dive hard w/ out picking up excessive speed. A Tiger Cub UL slips very well too, even w/ full flaps,so you can get into a tight field with ease.

For those individuals who want more power the 447 Rotax can be installed, but will put the UL over weight. The 447 Rotax is the largest recommended engine for the Tiger Cub UL. Performance however is impressive.

Plans: Plans include scale prints of the wings, tail surfaces, fuselage and bulkhead (panels). Full size prints of all the gussets and chromemolly parts. A complete material list, a vender list and a list of available parts packages. The plans also include an assembly manual (over 200 pages of pictures and text), that gives step by step directions and tips to guide you through assembly, rigging, covering, wiring, plumbing and finishing.Est.650 hrs build time.

The airframe is aluminum tube and gusset construction and requires only standard shop tools to build. There are a few chromemoly parts I.E. landing gear spindels, wing & tail universals, joystick socket, etc. Full size prints and 3D drawings of each part are included in the plans (if you don't weld you can order a chromemoly package from Johnston Aviation or take the prints to a local fabricating shop). We also offer a bent tube package (for builders that don't have access to bending equipment).
