You can't knock Saxon Microlights, they do indeed fly an old Thruster aircraft but that is purely what they do. I don't think they would even take a CTSW if they had the means to. Also at £102ph hour for flying training this is a snippet off the price tag of the normal PPL hour in the Cessna. The Thruster is £38 cheaper than learning to fly a CTSW at my field. This is definitely a cheaper option for getting in the air, but you are flying much less of an aircraft (almost like a powered kite)...
But they do look fun, I give them that. Isn't fun what flying is supposed to be about? I'd say!
