Unfortunately in science what you believe is irrelevant.

OK, let's put in language you will understand. I also fly aerobatics, free climb cliffs, base jump, cave dive, blue water sail, and ride a 150MPH sport bike. Let's just say that because of my not having a problem with getting in the face of the Elephant, I have done more living in my 62 years, than all the timid people on this planet combined could do in ten lifetimes.
HALS UND BEINBRUCH!!!
Fist consider if you want single or two seat. Next sort out the side by side or tandem if a two seater. If the Challenger is a contender be sure to check out the CGS Hawk (my favorite and a good used TDer aircraft is currently for sale if you are interested but I understand you want to build). If single seat suits you and you really did mean ultralight, is is amazing that no one has mentioned the Hyper Light by Sorrel. It is just what you are looking for.
