Most of the 80,s photos are slides I,ll have to upgrade.I will include the T600 photo if I can manage the system.My first flight in "ultralights'was a Jackaroo in1983,a broomstick without a windscreen,.then chinook,beaver then Gemini.allowable ceiling then was 300ft(idiots).There is a Kestrel which is a thruster lookalike I flew in N.T. Anothe good thing with a Thruster (unmodified) before the T500 is that it wont exceed VNE vertical dive making it pretty foolproof. There were many "prangs "in the early days and no one got hurt,at our school anyway.one pupil flew straight into a tree full power without a scratch. We even did some thermalling,and seabreeze front engine off flying. Its a different story these days,fast glass ships and much less forgiving. cheers
