It is a heavy machine due to the strengthening the U.S. Army required on the STA it was based on requiring a more powerful engine, the Kinner. They wanted a high wing loading aeroplane as an better introduction to characteristics of other aircraft they would fly. Hence it has a relatively high stall and approach speeds of 65/ 85. (Not using flaps as they don't do much and have a weak mechanism and can go asymmetric). As you can imagine this does not give the best glide or EFATO prospects. As you can see it is strong and was designed to protect the occupants. Just look at the frame ahead of the front seat passenger if you get the chance. I own and fly 854.
