If you can't find anyone closer to home then I would recommend going with Sandra Reid, at Old Sarum. I did just that recently and had a brilliant day out.
You might need a sense of humour, as she has, because coming from a 3 axis background will cause you some difficulties! and some sarcastic comments from the back seat. Flex wings steer the wrong way on the ground so the first task you will face will be taxiing slalom fashion down a row of cones on the way to the hold for the runway in use. "where are we going now?". Once in the air the "rudder pedals" don't achieve anything but that won't stop you instinctively using them. With all of the flight controls operating in reverse sense to what you are used to it will be "difficult" to maintain "straight and level", not made any easier when using a foot operated throttle to maintain airspeed. "I know you are a man but please try to concentrate on two things at once".
Nice one Sandra, I'll take you in a 3 axis sometime to get my own back.
