Shober Willie II
 
 Shober-Will2-01
Marshall Collins N602CB, Lycoming O-320 150 hp
 
The Shober Willie II is an American two-seat sporting or aerobatic aircraft designed and built by Shober Aircraft Enterprises.
 
The Willie II is a braced single-bay biplane with a fabric covered welded steel fuselage. The two-spar wooden wings are fabric covered with wide-span ailerons on the lower wing and a fabric covered wired-braced welded steel tail unit. The prototype is powered by a 180 hp (134 kW) Lycoming O-360-A3A engine. It has two open cockpits in tandem and a fixed conventional landing gear with a tailwheel.

First flying in 1971, the aircraft was designed to be sold as plans for amateur construction.
 
Suited for engines in the 150 to 200 hp range, at least four further aircraft were completed. Further development was halted in 1976 when the type was withdrawn from the market.
 
 Shober-Will2-03
 
The Willie II has the M-6 airfoil and two ailerons. The Skybolt Biplane with symmetrical airfoils and four ailerons came out shortly after the Willie II, possibly that is why the Willie II plans were withdrawn from the market.
 
There appears to have been five Willie II biplanes built;
