Classic motorglider info please

I am deciding on a homebuilt project. I am considering a project like
the classic Fournier motorgliders. I believe they are called touring
motorgliders. Thr RF4 style or my favorite looking plane, the
Schleicher ASK-14, is the type I'm refering to. Powered flight would
be my primary purpose to fly this style of plane. I own a Bowers
designed Fly Baby and fly in Canadian UL aircraft of 450kg/1000lb
gross wt. ratings. My needs are met by a single seat craft.

I enjoy these planes but the style of flight that is increasingly
appealing to my taste is elegant low powered flight with some soaring
flight. I live near the Canadian Rockies and have wave oppurtunity
close to home. The high drag and poor glide of most UL planes
concerns me.

I have noticed a German plans built machine, EEL's ULF-2.

Does anyone know much about this plane?

What are the flying traits of these touring motorgliders? One site
raves about the touring and flight qualities of the RF4.

Are there any older plans built types that were available in the past?
