With out converting your weight into kg I'm not sure,
But it it helps...I fly the forerunner to the Blade...a 1993 Flash 2 Alpha...they have the same cockpit seat loading at 110kg max...with a total cockpit load of 180kg...with a total mauw of 370kg,
Some of the later machines such as the GT450 have a mauw of 450kg...not sure about there seat limit though....but much more expensive,
P.S. just found an on line converter...the pair of you work out about 185kg...so your not far off there....have to get granddad to try and shed a few kgs,
Hope that helps.
Nick.
