Apologies for the erratic behaviour of the forum software lately - it is making a mess of rendering the posts and is difficult to read.
This appears to be being caused by old system code that contains deprecated commands and syntax no longer used by the latest version of PHP running on the server. I have raised the matter with both the forum and Joomla software developers, but it may take a while to get fixed.
A dual tow hang glider and glider (Carbon Dragon) Gloucester NSW. We did it with a Rotax 582 on an Edge X with a Wizard wing. The 582 has plenty of power could have easily hooked up an extra glider!
