Well, what a fuss. I flew for ten years without any sort of radio, and we only installed a transponder three years ago. Never stopped me traveling. Flew from Poland to the west coast of France radio inop, no transponder, which involved a certain amount of telephone calls. Flew for six months generator inop, and have never had a stall warning on the Cub or any of the gliders I fly, two of which at least had «interesting» behavior at the stall.
This is VFR flying, people. Use the real horizon, map, and compass, stopwatch. Use the radio if you want, learn to handprop. I can hand start an O—360 on a taildragger, and I am far from tall. (OK, now is probably not the moment to learn, get someone to teach you properly)
This is a Maule, not a 747 we are talking about. Mind you, with the forecast as it is for the next couple of days, looks like a couple of days holiday in Rennes is on the programme.
Enjoy the food and wine!
