I've been doing some flying recently in a 90hp Cub (a PA19), and loving it. On a hot summer afternoon, nothing is nicer than flying along at low altitude with the doors open at 60 or 70mph. It's probably the perfect aeroplane for spotting mountain goats in the Alps!
There are a few things I don't like so much though. The controls are heavy, especially in pitch (at least compared to the Jodels I normally fly) and the heel brakes are horrible and not very effective. Also, of course, if one wants to go somewhere as opposed to just bumbling along frightening goats, it's a wee bit on the slow side.... a Jodel is about 20kts better on the same engine.
