I instruct on a sky ranger and a pioneer 200. Both excellent aircraft in their different ways. However, my most fun is in the Super Cub, which I can take on holiday stuffed full of the camping kit, husband aka navigator and alternate pilot, fill up the tanks and fly for six hours. Slow, noisy, and uncomfortable yes. Sturdy, short field performance as well. 70 knots with the fine pitch prop, 25 litres per hour. Frankly, the fuel isn't the most expensive part of flying. The cub's value has actually appreciated substantially since we bought it, if we sold it we would get most of our money back. That's not why we chose it. Flying is supposed to be fun.
