  • Bearhawk Layout Comparison LSA - Supercub

    (All dimensions are approximate and for rough comparison only)

    (See side view photo bellow - click on photo thumbnails at bottom for larger view)

    6'4" 195lb pilot and 5'7" 130lb passenger shown. The LSA occupants are drawn in white with black outlines. The pilot in the LSA is situated in the middle seat adjustment position. The Supercub occupants are drawn in light grey.

    The LSA is drawn with 22" tall tires. (Desser 850-6 Aero Classic Tundra) Both aircraft show a 74" diameter prop.

    The photos bellow show an approximate size/layout comparison between the LSA and a Supercub. The LSA is drawn to scale (black lines), and I have the Cub fuselage tubing layout and a 3 view faded in the background.

    The Supercub has approximately a 3" taller cabin at the pilot (floor to roof) but this is difference is largely cancelled out due to the foot position of the pilot being several inches higher in the cub. (the bottom longerons and floor taper up towards the firewall in the rudder pedal area) The LSA appears to have slightly more room between seat bottom and roof. The cub is around 26" wide in the cockpit and the LSA looks to be 4-5" wider. The LSA pilot sits around 4" farther back from the firewall than the Cub. The LSA pilot and passenger have around 5" more room between them than the Cub. The LSA looks to have more room from the knees to instrument panel. The LSA landing gear axles are around 2" farther forward than the stock cub. The distance from the bottom longeron to the axle line is nearly identical between the LSA and Cub with the gear in the neutral position. (axles parallel, gear slightly compressed) The Cub has around 72" between center of tread, and the LSA has 68". The LSA gear is shorter than the cub, and sits at a steeper angle when viewed from the front. The LSA and Cub appear to have similar over the nose visibility.

    The Cubs tube fuselage is around 214" long, and the LSAs is around 208".

    That looks like the result of a lot of research!

      Us tall guys will go to great lengths to avoid hitting our head and knees... It's good to see a line of aircraft designed to accommodate larger pilots. I'll fine tune the seat height for max visibility over the nose, while maintaining sufficient head room around the main spar carry through and fuselage bracing. It looks like if I keep the seat cushion reasonable, it should be just right.
