The Stinson L-5 Sentinel was a World War II era liaison aircraft used by all branches of the U.S. military and by the British Royal Air Force. Along with the Stinson L-1 Vigilant, the L-5 was the only other American liaison aircraft of World War II that was purpose-built for military use and had no civilian counterpart. All other military liaison airplanes adopted during World War II were lightly modified "off-the-shelf" civilian models.

From Wikipedia, the free encyclopedia


The STINSON L-5 “Sentinel” is an ideal model for those who want to scratch build an economical giant scale warbird with docile flight characteristics. Probably one of the best "warbugs" for flying off of all types of fields (grass or pavement) in all types of weather.

Nick named "The flying Jeep", it handles all field conditions with ease. Construction is an all wood built-up structure that is simple and straight forward utilizing conventional materials and assembly techniques. The model features a two piece wing design for easy transportation and yet provides easy assembly/disassembly at the field. The plans show all structures and parts drawn full size with template outlines provided for all major parts. The plans also show the installation of flaps and leading edge slots. If you would like to purchase a wood kit see KIT CUTTER'S on selection bar at the top of each page.Parts available are: fiberglass cowl, formed and welded wire landing gear, vacuum-formed plastic L.G. covers and blisters and dummy exhaust stacks, vacuum-formed plastic tail cone. A five channel radio is required.

The 1/4 scale L-5 can use 5.50 Dubro balloon style wheels for those really soft fields or thick uneven "un-improved" grass runways. The pilot (and "back seater") required is a "militarized" 1/4 scale civ pilot.
