Curtiss JN–4D "Jenny"
Flight Notes - how to fly the Curtiss JN–4D "Jenny
Glenn Curtiss's motivation for developing the JN–4 may have derived from the number of fatalities he witnessed among student pilots in the first decade of powered flight. By the time Curtiss was well into several iterations of the design, a war was in full flame in Europe. The Royal Flying Corps was his first large customer and that order did much to further the "Jenny's" popularity as a trainer (it was not agile or fast enough to serve as a fighter).
If the Extra 300 is like riding a thoroughbred racehorse, flying the Jenny is like riding an elephant. It's big and slow, and responds to control inputs at its own pace. The preflight checks are extensive, verifying that all the wires, struts, fabric, and sundry other parts are in place. The best climb you'll get out of the Jenny on a cool day is about 400 feet per minute (122 meters per minute), but she was the workhorse of her day and much beloved by her pilots.
Keep in mind that the difference between flying the Jenny and flying a plane like the Cessna 172 is the Jenny's large size, underpowered climb capability, and slow response. Plan ahead and keep a hand on the throttle during landing.
