Here are plans for the Aeronca 7AC that I electronically scanned from my purchased copy of the January 1968 American Aircraft Modeler magazine. You might be able to scale up the image below if suitable plans cannot be located. Plans for this fine model were drawn by Mr. Paul R. Matt. All copyrights (if any) are hereby acknowledged.
"The Aeronca Model 7 Champion, more commonly known as the Champ, is a single-engine, two-seat, fixed conventional gear airplane. Designed for flight training and personal use, it entered production in the United States in 1945." - Wikipedia
The AMA Plans Service offers a full-size
version of many of the plans show here at a very reasonable cost. They will scale the plans any size for you. It is always
best to buy printed plans because my scanner versions often have distortions that can cause parts to fit poorly. Purchasing
plans also help to support the operation of the Academy of Model
Aeronautics - the #1 advocate for model aviation throughout the world. If the AMA no longer has this plan on file, I
will be glad to send you my higher resolution version.
