Madbob ...
Glad you liked the pics ... But all the credit goes to our good friend Dragartist who was running the trials ... I'm just helping him post his pics
That said, I reckon you're about right with 400/500 AGL eyeball estimate ... Which is backed up by what AA62 has said above
Sorry but ... I personally never understood the 'desire' to jump out of a perfectly serviceable aeroplane ... But gladly salute those that do on behalf of HMTQ
