Today we start the upper wings. This is where the Delta variant is different. The wings are shorter than standard due the larger centre section. This upper wing and cabane structure is like a Stearman of Pitts Model 12.

Note the cabane difference from standard. This is the outward leaning cabane that has been designed here… is almost identical to the Pitts Model 12

L: Pitts Model 12 R: Stearman
