om...
I use to fly on the SF28 for a few years and would like to buy a 2
seats touring motor glider as the Dimona HK36, Grob 109 or the Taifun
E17.
I'm a bit concerned by poor soaring performances reported by
occasional flyers or good performances reported by the vendors!!
Who could report on owner soaring experience of this type of
motogliders?
Thanks a lot



You might look at the VANS AIRCRAFT page and read the stuff on the RV11.
This is his motorglider project. There is a nicely written page on
configuration, soarability
ans l/d, sink rates and so on.

Hope that helps....
