Bob,
You probably won't find anything on the Glider.
Designed to take crew weight up to 70kg.
If you were looking at the older kids or light weight adult market and were going to have a stayed mast it would be hard to go past.
I think I still have the specs somewhere. I'll dig them up and send them to you if you like.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
